NVIDIA GeForce GTX 750 Ti 2GB Video Card Review — Maxwell Architecture For Under $150
NVIDIA GeForce GTX 750 Ti 2GB Video Cards Arrive
NVIDIA today announced the new GeForce GTX 750 Ti and GTX 750 video cards, which are very interesting to use as they are the first cards based on NVIDIA’s new Maxwell graphics architecture. NVIDIA has been developing Maxwell for a number of years and have decided to launch entry-level discrete graphics cards with the new technology first in the $119 to $149 price range. NVIDIA heavily focused on performance per watt with Maxwell and it clearly shows as the GeForce GTX 750 Ti 2GB video card measures just 5.7-inches in length with a tiny heatsink and doesn’t require any internal power connectors!
NVIDIA GeForce GTX 750 Series Cards:
- NVIDIA GeForce GTX 750 Ti 2GB – $149
- NVIDIA GeForce GTX 750 Ti 1GB – $139
- NVIDIA GeForce GTX 750 1GB – $119
NVIDIA says that the Maxwell architecture used on the new GM107 (the GPU core used on the GeForce GTX 750 and 750 Ti) has allowed them to produce the most efficient GPU ever built. Kepler was revolutionary for performance per watt when it came out and so it Maxwell. Kepler was on manufactured on the 28nm process and was essentially an upgrade from the previous Fermi architecture that was done on the 40nm process node. NVIDIA has taken everything they’ve learned from their Tegra line of mobile processors and the Kepler desktop and enterprise processors and put all that expertise to good use in Maxwell. Maxwell has 135% more performance per core and twice the performance per watt. Added more control logic to the CUDA cores. Maxwell logic is better so they can control more cores controls fewer cores. The image above shows a very high-level block diagram that highlights the fact that NVIDIA greatly reduced the shader block sizes into smaller clusters with added control logic. This allows them to to better control the CUDA cores on each particular Maxwell GPU and really helps improve the efficiency.
Here is a nice table that shows a high-level comparison of the GM107 Maxwell GPU versus the previous generation Gk107 Kepler GPU.
The GM107 ‘Maxwell’ GPU has 640 CUDA cores with 1.87 Billion transistors and a die size of 148mm2. The NVIDIA GK107 ‘Kepler’ GPU had just 384 CUDA cores with 1.3 billion transistors and a die size of 118mm2. The really cool thing is that NVIDIA’s GM107 has higher performance specs and has a slightly lower TDP even though it has 570 million more transistors at the same 28nm manufacturing process!
NVIDIA says that gamers generally upgrade their video card on every four years on average and that the new GeForce GTX 750 Ti will give those people a huge boost in power efficiency. NVIDIA believes that the GeForce GTX 750 Ti will be about a 2x performance upgrade at a fraction of the power use for those still using a GeForce GTX 550 Ti video card from 2010.
NVIDIA has taken notice of the boom in Mini-ITX gaming PCs and think that the GeForce GTX 750 Ti is a perfect match for someone looking to build a 1080P small form factor (SFF) gaming PC as you need just a 300W power supply and there is no 6-pin power connector needed on the GeForce GTX 750 Ti reference card.
Some manufactures will be putting a 6-pin PCie video card power connector on the boards, but from what we can tell it should be needed even when overclocking. Why is that? NVIDIA has placed overclocking restrictions on the GeForce GTX 750 Ti and right now the BIOS only allows the CUDA cores to be overclocked by 135MHz. The memory isn’t locked down, so the sky is the limit there.
NVIDIA originally planned for the GeForce GTX 750 Ti to be in direct competition with the AMD Radeon R7 260X, but it appears that last weeks launch of the AMD Radeon R7 265 2GB video card at $149 spoiled that. The NVIDIA GeForce GTX 750 Ti looks like it should perform as fast or faster than the AMD Radeon R7 260X across the board and it should do it cooler and quieter.
NVIDIA says that in this scenario (R7 260X versus GTX 750 Ti) that in your average gaming scenario that the typical board power will drop from 115W to 60W while at the same time you are getting better performance
NVIDIA says that the the first graphics cards to use the first-generation Maxwell architecture were designed to do more with less, so keep that in mind when looking at the specifications here.
The NVIDIA GeForce GTX 750 Ti has 640 CUDA Cores that have a base clock of 1020MHz and a boost clock of 1085MHz. The GTX750 Ti supports NVIDIA Boost 2.0 technology, which means that it the parameters are okay that they card can clock higher than this. The GeForce GTX 750 Ti uses a 128-bit GDDR5 memory bus and you have the option of purchasing a 1GB or 2GB model. The memory is clocked at 1350MHz (5400MHz effective) and that gives you about 86.4 GB/s of memory bandwidth. The NVIDIA GeForce GTX 750 Ti should be used with a 300W or greater power supply as it has a TDP rating of just 60 Watts. The GeForce GTX 750 Ti supports DVI, VGA (D-Sub), HDMI and DisplayPort video outputs, so you’ll see a variety of options in the retail market. The one thing we need to point out is that you might want to go out of your way to find a model with DisplayPort 1.2 if you pan on purchasing an NVIDIA G-Sync monitor as it is required for G-Sync to work. You’ll need to look for an Add-In-Board (AIB) Partner that has DisplayPort 1.
2 on their card. It would have been nice if NVIDIA didn’t make Displayport 1.2 optional on these entry level gaming graphics cards, but it is too late now. The GeForce GTX 750 Ti also does not support HDMI 2.0.
The NVIDIA GeForce GTX 750 is basically the same thing as the as the except it has fewer CUDA cores, just 1GB of GDDR5 memory and a 5W lower TDP. NVIDIA reduced the number of CUDA cores from 640 to 512, which is a 20% reduction. The number of texture units drops from 40 to 32 and the number of ROPs remains the same at 16. NVIDIA is exploring the idea of releasing a 2GB version of the NVIDIA GeForce GTX 750, but right now there will just be a 1GB variant. The NVIDIA GeForce GTX 750 will cost $119.99 at launch and will be competing in the marketplace against the AMD Radeon R7 260X 1GB that also shares an MSRP of $119.99.
The NVIDIA GeForce GTX 750 and 750 Ti will replace the GeForce GTX 650 Ti series in the GeForce line-up. This means that they will be above the GeForce GTX 650 and below the GeForce GTX 660 in terms of price and performance.
Today Legit Reviews will be looking at the NVIDIA GeForce GTX 750 Ti 2GB reference card along with custom cards by ASUS and MSI.

Gigabyte GeForce GTX 750 Ti OC Review (GV-N75TOC-2GI)
Today we are going to look at one of NVIDIA’s mid-range graphics card featuring the company’s first generation Maxwell graphics processor that offers lower power consumption and decent performance at an affordable price. I have here the Gigabyte GeForce GTX 750 Ti OC (GV-N75TOC-2GI) featuring the company’s WindForce 2X GPU cooler, Ultra Durable 2 components and supports 4K resolution at 60Hz. The GV-N75TOC-2GI comes with a factory overclock settings, a base clock speed of 1033MH, boost clock of 1111MHz and 2GB GDDR5 memory. Are you planning to build a budget friendly gaming rig powered by a GeForce GTX 750 Ti? Please continue reading my Gigabyte GeForce GTX 750 Ti OC review below and find out if this is the graphics card that should be on your list.
Gigabyte GeForce GTX 750 TI OC Review
Gigabyte has released four different graphics based on the GeForce GTX 750 Ti Maxwell GPU. They have the GL edition, the WindForce OC edition, the Black Edition, and the GV-N75TOC-2GI overclock edition. For this review we are just going to focus on the GV-N75TOC-2GI.
The Gigabyte GeForce GTX 750 Ti OC features a base clock speed of 1033MHz and a Boost clock speed of 1111MHz. It’s a tad higher compared to the reference speed which is 1020MHz and 1085MHz respectively. It is built with 2GB GDDR5 memory running on a 128-bit memory interface.
It supports PCI Express 3.0 x16 bus interface, Dual-link DVI-I and DVI-D ports, and 2x HDMI ports. It also requires that you have at least a 400w power supply, and unlike other GeForce GTX 750 Ti (including the reference one) Gigabyte’s GTX 750 Ti requires you to connect the graphics card with a 6-pin PCIE power connector.
Even though this is just a mid-range budget friendly graphics card, it can support 4K display at 60Hz speeds via two HDMI ports for desktop and multimedia use.
But when it comes to gaming with 4K display, don’t expect to get decent frame rates (even playable frame rates) with a GTX 750 Ti. The GV-N75TOC-2GI also features the company’s renowned WindForce 2X GPU cooler providing a much better cooling performance compared to the reference one.
Aside from that, Gigabyte is also known for their robust and stable components. The Gigabyte GTX 750 Ti OC features Ultra Durable 2 components such as Ferrite Core Chokes, Low RDS (on) MOSFET and Lower ESR Solid Capacitors, and sophisticated layout topology. I’ll discuss more of the graphic card’s features as we take a closer look below. You can also check out its detailed specifications on the table below.

A Closer Look at the Gigabyte GV-N75TOC-2GI
The Gigabyte GeForce GTX 750 Ti OC comes in a simple and straight forward box. However, I’m wondering why Gigabyte is using an “Owl” (if I am not mistaken) on their box, since one of their competitors also has an “owl” branding. Anyway, the main features of the graphics card can be read on the back side of the box.
The package includes a small quick guide pamphlet, a driver CD, a 6-pin PCIE power adapter and the graphics card itself.
Above is the front and back view of the Gigabyte GTX 750 TI OC. It measures 204mm in length, 144mm in width and it’s just 42mm thick occupying two PCI slots. The shroud is made of plastic and the holographic sticker on the fans looks cool. Notice that the heatsink and the rear fan extends a little bit, not really a big deal in my opinion.
Above are different angles of the graphics card. I’m sure you already noticed that the card’s PCB is color Blue, since it’s very obvious. I wonder why Gigabyte opted to use Blue instead of the more popular Black PCB. Most of its competitors are using black PCB and many would prefer a black PCB. Only their GTX 750 Ti Black Edition features a black PCB. I hope Gigabyte would use a black PCB in their future graphics cards regardless of the model or edition.
Unlike most of the GeForce GTX 750 Ti graphics card out there, the Gigabyte’s GTX 750 Ti has a 6pin power connector, and that is not an optional power input.
The card will require you to connect an external power via a 6-pin PCIE power connector.
You might be wondering why Gigabyte opted to draw power from a PCIE instead from the motherboard itself. NVIDIA built the GTX 750 Ti and GTX 750 to be so power efficient that it can function properly by drawing power from the motherboard alone. But there are non-reference GTX 750 Ti, not only Gigabyte’s, which draws its power directly from a 6-pin PCIE power. I asked Gigabyte why, and they told me that they will never know what motherboard their customers will be using. According to them, the quality and the power that a motherboard can provide to the graphics card differs from one brand and model to another. So to be safe, it’s best to draw power directly from the power supply to ensure stable and sufficient power.
In my opinion, while it’s good to play safe, I think it’s still best that it did not come with a 6 pin power connector since that is one of the main feature of a GTX 750 Ti (to be power efficient).
People might think that it’s more power hungry compared to other GTX 750 Ti out there, since it requires an external power. Anyway, if a user messed up his graphics card because he installed it on a low end motherboard, or (worst) a crappy low quality motherboard, I think that is no longer Gigabyte’s fault if the graphics card got damage.
On the output ports of the Gigabyte GV-N75TOC-2GI it has two DVI ports, and two HDMI ports. You can connect up to 4 displays using this graphics card, and it also supports 4K display monitor at 60Hz via two HDMI ports. Yes, you have to connect the two HDMI ports to your 4K display to take advantage of the 60Hz speed.
Although it supports 4K display at 60Hz, this does not mean that you will get decent frame rates when gaming on a 4K monitor. The GeForce GTX 750 Ti is built for 1080p gaming and not 4K. You will need a more powerful graphics card, like the GTX 780 Ti, to enjoy 4K gaming.
Above are photos of the Gigabyte WindForce 2X cooler.
It has two fans with semitransparent fan blades, and the heatsink features 1 copper heatpipe that transports the heat from the GPU to the aluminum fins. The cooler may look big for the GPU, but I think the size is just right considering that it does the job of cooling the graphics card very well.
On this angle, you will notice that the fan blades are slightly tilted. That’s not a camera trick, those fans are really tilted. That’s actually one feature of the WindFore 2X cooler. It pushes the heat from the heatsink towards the rear end of the graphics card. But I think the fans should be tilted on the opposite direction so that it will push the heat towards the exhaust and outside the system.
Above are photos of the front and rear view of the Gigabyte GeForce GTX 750 Ti OC PCB. There’s nothing special or fancy about this card and it’s pretty much straight forward. According to Gigabyte they are using a sophisticated layout topology that delivers the ideal integration of thermal, electric characteristics, digital signals, power circuitry and optimum placement of components for enhanced graphics performance.
The Gigabyte NV75TOC-2GI uses four Samsung K4641325FC-HC03 memory chips for a total of 2GB GDDR5 running on a 128-bit memory interface, and they are rated to run at 5400MHz effective clock speed. The other picture shows a closer look at the 28nm GM107-400-A2 Maxwell silicon, that is the heart of the GTX 750 Ti graphics card. The GM107 features 640 CUDA cores, 40 TMUs and 16 ROPs. The reference GTX 750 Ti has a base clock of 1020MHz and 1085MHz Boost clock speed.
Test Setup
In testing the Gigabyte GTX 750 Ti OC, I’m using a new Z97 motherboard, the Gigabyte Z97X Gaming G1 WiFi Black Edition, powered by an Intel Core i7-4770K. Also during the test, I am using NVIDIA 9.18.13.4052 (ForceWare 340.52) driver version for Windows 7 64bit. Below are the rest of the specifications of the test system.
Operating System: Windows 7 Ultimate 64bit
Motherboard: Gigabyte Z97X Gaming G1 WiFi Black Edition
Processor: Intel Core i7-4770K
CPU Cooler: Corsair Hydro h205
Memory: 16GB Avexir Blitz 1.
1 DDR3 1600MHz
Graphics card: Gigabyte GeForce GTX 750 Ti OC (GV-NV75TOC-2GI)
Hard Drive: Kingston HyperX 3K 120GB for the OS and WD RE 4TB for game files
Power Supply: Seasonic X750 Gold Series v3
Overclocking the Gigabyte GeForce GTX 750 TI OC
Overclocking the Gigabyte GTX 750 Ti OC further was easy. I used Gigabyte’s OC Guru II and I tried to push its GPU clock speed to 1240MHz, boost clock speed to 1318MHz and memory clock speed to 1425MHz (5700MHz effective). That’s 20% increase in terms of core clock speed, and 18.63% increase in boost clock.
I’m sure the base, boost and memory clock can still be pushed further, but I’m just not a fan of overclocking your graphics card too much. Better get the next faster graphics card than pushing your card to its limit. Not only will overclocking result in more heat and power consumption, but it may decrease the life of the GPU as well.
Gigabyte GTX 750 Ti OC Temperature and Fan Noise
I was impressed with the silent PWM fans on the Gigabyte GTX 750 Ti OC.
Although the GTX 750 Ti doesn’t produce much heat due to its low TDP, the WindForce 2X cooler design does a great job in cooling the graphics card. On idle I’m getting around 25 degrees Celsius only. The temperature goes up to 35 degrees to 45 degrees Celsius when in full load (stock speeds). And when overclocked, with the clocked speeds I mentioned above, the highest temperature I got at full load is just 63 degrees Celsius, around 55 degrees on the average. The fans are pretty silent as well. It’s barely noticeable on idle to medium load, and at full load the fans are still running whisper quiet.
Gigabyte GTX 750 Ti OC Benchmark Results
Below are the benchmark results I got while testing the Gigabyte GV-NV75TOC-2GI. The first graph is the Gigabyte GTX 750 Ti OC running with an Intel Core i7-4770K processor.
The second graph below is the Gigabyte GTX 750 Ti OC running with an Intel Pentium G3258 Anniversary Edition processor. I don’t think that the processor is already a bottleneck, but paring it up with a much faster quad core processor will give you an overall better performance.
“3DMark 11 is a DirectX 11 video card benchmark test for Windows. 3DMark 11 makes extensive use of DirectX 11 features including tessellation, compute shaders and multi-threading. It includes the Deep Sea and High Temple Graphics tests, a Physics test and a Combined test.”
“3DMark Fire Strike is a showcase DirectX 11 benchmark designed for today’s high-performance gaming PCs. It is our most ambitious and technical benchmark ever, featuring real-time graphics rendered with detail and complexity far beyond what is found in other benchmarks and games today.”
“3DMark Sky Diver is a DirectX 11 benchmark for gaming laptops and mid-range PCs. Use 3DMark Sky Diver to benchmark systems with mainstream graphics cards, mobile GPUs, or integrated graphics. It is especially suitable for DirectX 11 systems that cannot achieve more than single-digit frame rates in the more demanding Fire Strike test.”

Below are actual game benchmarks of the GV-NV75TOC-2GI. All games are set to their highest settings, with V-Sync turned off and monitor resolution is at 1920×1080. The minimum, average and maximum frames per second were extracted using Fraps. Meanwhile I used the built-in or in-game benchmarking tool for the Tomb Raider and Metro Last Light.
Below are the benchmark results from CompuBench. The left side is the result using the stock settings, while the right side is the result I got after overclocking the graphics card.
Price and Availability
The Gigabyte GeForce GTX 750 Ti OC (GV-N75TOC-2GI) is widely available since it has been on the market for quite some time now. Currently it retails for $148.99, available here. In other countries, it retails for £104.98, or around Php 7,400.
The GV-N75TOC-2GI is actually the cheaper model compared to the Black Edition. If you want to save money, better get this one instead and just overclock it to match the performance of the other SKUs.
Gigabyte GeForce GTX 750 TI OC Review: Conclusion
After several weeks of testing and using the Gigabyte GeForce GTX 750 Ti, I find no flaws or hiccups on this card. The graphics card is working as expected, and since Gigabyte has set a pretty conservative factory overlock settings, the clock speeds can still be pushed further.
In terms of temperature and cooling performance, the WindForce 2X cooler gets the job done perfectly. It might be a little bit overkill for the GTX 750 Ti, but you can rest assure that the Gigabyte GTX 750 Ti is running cool and quiet even at overclocked settings.
I don’t really mind the additional 6-pin power connector. It’s no biggie for me, but I think it would be better if it didn’t require an external power source, or at least make it optional. However, that blue PCB does hurt in terms of aesthetics. Some or many may not find a graphics card with a blue PCB pleasing to the eyes. Oh, I think the Gigabyte OC Guru II needs improvement as well in terms of user interface.
Overall, the Gigabyte GeForce GTX 750 Ti OC (GV-N75TOC-2GI) is a great solid graphics card. It’s very cool and quite, can still be overclock further and pricing is competitive as well. I would have given it with an Editor’s Choice award if not for the blue PCB, and probably the required 6 pin power connector. But this card still deserves an award, and that’s The PC Enthusiast’s Highly Recommended award.

Of course, MSI, one of the main partners of NVIDIA, could not ignore such an important event as the release of the new 28nm NVIDIA Maxwell microarchitecture, which is focused on creating energy-efficient solutions for compact desktop and mobile systems.
Recall that on its basis two new graphics adapters have already been presented: NVIDIA GeForce GTX 750 and NVIDIA GeForce GTX 750 Ti.
In connection with the events described above, the video card MSI was born GeForce GTX 750 Ti TWIN R GAMING ( N 750 GD 5/OS) , which offers its customer a fairly large list of advantages compared to the reference solution. It is on these features of the novelty that we will focus in this review.

4 Since the legacy of the reference solution, the new product inherited only the graphics core and video memory subsystem, we can conclude that MSI paid a lot of attention to improving this video card.
Judge for yourself, it includes: an original printed circuit board, a branded cooler, a reinforced power subsystem and a rather interesting ability to switch between three operating modes, which will allow you to flexibly manage performance and power consumption depending on current tasks.
Packaging and Contents
The packaging of the MSI GeForce GTX 750 Ti TWIN FROZR GAMING is made in the typical design of the MSI GAMING series: red and black colors predominate, as well as the series logo (stylized dragon). In addition to the name of the video card and the manufacturer, it is worth noting the presence of the “OC Edition” logo, which indicates the factory overclocking of key parameters.
All the important information is on the back of the box. Most of the free space is occupied by a description of the key advantages of the video card, namely:
- GAMING APP — a proprietary software is supplied with the graphics adapter, with the help of which the function of quickly switching between three different modes of operation of the graphics adapter is implemented: Silent, Gaming and OC.
Each of them will be relevant depending on the current tasks of the user. - Military Class 4 — the production of new items uses a high-quality element base with a high level of efficiency and reliability (ferrite chokes, solid-state and tantalum capacitors).
- Twin Frozr IV Advanced is a proprietary cooling system that provides lower noise levels as well as more efficient cooling than the reference cooler.
- Predator — using the built-in utility, you can save any game process in full screen mode. Predator is marketed by MSI as a free alternative to the highly popular Fraps, which costs about $37 for a licensed version.
The list of system requirements for the computer in which you plan to install MSI N750Ti TF 2GD5/OS is also located on the back of the package. Based on these recommendations, the power supply should have a power of at least 400 W, while you will not need additional power cables.
In the box with the video card, we found only standard instructions and a software CD. Considering the affordable price of the novelty, the configuration of its interface panel, as well as the lack of connectors for additional power supply, this set is quite expected and sufficient.
A modified set of video outputs is provided for displaying images on the graphics adapter:
- 1 x DVI-D;
- 1 x HDMI;
- 1 x D-Sub.
As you can see, this configuration will allow you to avoid using any adapters to connect different monitors. Recall that the «reference» interface panel includes two DVI ports and one mini-HDMI, which will require the use of an additional adapter for owners of analog displays.
The following resolutions are supported:
- Digital — up to 4096×2160;
- Analog — up to 2048×1536.
Appearance and element base
improved design.
Its dimensions are noticeably larger than the reference indicators (262 mm in length versus 159 mm).
The tested video accelerator is powered by an enhanced five-phase circuit (four phases for the GPU and one for the memory chips), which is two phases more in the GPU power circuit than the reference design suggests. The element base is recruited in accordance with the Military Class 4 concept and includes exclusively high-quality components: ferrite chokes (SFC), tantalum (Hi-C) and solid-state (Solid) capacitors with increased efficiency and extended service life.
The core power subsystem is implemented on the uPI Semiconductor uP1608TK digital PWM controller. Depending on the modification, it supports the control of a maximum of four phases, and also has a number of protections against overvoltage.
As in the case of the «reference» NVIDIA GeForce GTX 750 Ti, the new items are powered exclusively by the PCI Express 3.
0 x16 slot. Although the PCB has a slot for a 6-pin power connector, which tells us about the possible release of modifications that will need it.
Separately, we note that on the side of the MSI N750Ti TF 2GD5/OS video card there is a switch between two BIOS firmwares: Legacy BIOS and Hybrid BIOS.
The reverse side of the printed circuit board is notable except for the mounting screws of the cooling system, as well as several components of the power subsystem. There is a special sticker on one of the screws, so removing the cooler without voiding the warranty will not work.
(OC mode)
(Gaming mode)
(Silent mode)
The tested novelty is based on the NVIDIA GM107 (Maxwell) graphics chip. It is produced on a 28nm process and consists of 5 active SMM units, 640 universal shader pipelines (CUDA cores in NVIDIA’s terminology), 40 texture units and 16 rasterization units. In the nominal mode of operation (which is the OC mode), the base frequency of the graphics core was increased to 1085 MHz, and thanks to the support of GPU Boost 2.
0 technology in the turbo mode, its average speed is 1163 MHz.
The memory of the tested video card, with a total capacity of 2 GB, was built using 4 SAMSUNG K4G41325FC-HC03 chips with a capacity of 512 MB each. According to the documentation, their nominal effective frequency is 6 GHz, but the manufacturer lowered it to the reference 5400 MHz. Data exchange between the graphics core and memory is carried out through a 128-bit bus, which is capable of passing 86.4 GB of information per second.
Cooling system
New with Twin Frozr IV Advanced cooling system installed, occupies two expansion slots and has a total length of 250mm according to MSI’s official website (262mm according to measurements in our test lab).
The cooler itself consists of a fairly large heatsink made up of 36 longitudinally arranged nickel-plated aluminum plates, two fans with a Propeller Blade design and a blade diameter of 95 mm, as well as from a plastic casing that covers the entire structure from above.
Two heat pipes, 8mm and 6mm, are used to improve heat transfer efficiency. Note that they are coated with a layer of nickel, which is used to reduce the risk of possible oxidation of copper.
As you can see, the technology of direct contact of heat pipes with the graphics core through a small layer of thermal paste is used. Unfortunately, field-effect transistors and video memory chips lack additional cooling, which, in theory, can adversely affect overclocking potential.
We also recall the presence of a special stiffening rib on the upper edge of the printed circuit board, which supports the structure and prevents damage to the textolite.
With automatic regulation of the fan blades rotation speed, in the maximum load mode, the graphics core heated up to 57 degrees, and the cooler, judging by the monitoring readings, worked at only 36% of its maximum power. The noise level at the same time, according to subjective sensations, can be described as “quiet”.
It absolutely does not stand out from the background of other components and in no way interferes with your use.
In the maximum fan speed mode, the GPU temperature dropped to 47 degrees. At the same time, the noise level can be described as “slightly above average”. It was not intrusive, which is an indisputable advantage of this cooler.
When there is no load, the graphics core and memory frequencies are automatically reduced to reduce their power consumption and heat dissipation. In this mode, the temperature of the GPU did not exceed 31 degrees.
In general, the Twin Frozr IV Advanced cooling system is one of the best among all NVIDIA GeForce GTX 750 Ti modifications we have tested so far. It has a high power reserve and low noise level, which was achieved due to the optimal selection of the parameters of the passive and active components of its design.
