Corsair Hydro H75 Review

Manufacturer: Corsair
UK price (as reviewed):
US price (as reviewed):$84.99

When we looked at the Corsair Hydro h205, we noted that its design was similar to the h200i but that it featured a thicker radiator. Similarly, the newest 120mm radiator model in Corsair’s closed-loop lineup, the H75, bears many resemblances to the well received H80i, with a key difference again being radiator thickness. In this case, however, the H75 radiator is slimmer, coming in at 25mm compared to 38mm. It’s therefore no thicker than a standard case fan.

At £61, the H75 is in competition with a number of big flagship air coolers. Also, while it’s more expensive than the H60, it does come in cheaper than the H80i and the 140mm H90. The differences between these coolers often aren’t much, as they are all based on single radiator designs, but there’s enough variety to allow Corsair to adequately cover a decent range of price points.

The H75’s tubing is lower in diameter than that of the H80i. It may therefore have a more limited flow rate, but equally it should be easier to manoeuvre within tighter spaces. We certainly found it to be very flexible and Corsair’s claims of it being kink-resistant also proved true in our experience.

As with all of its recent liquid coolers, Corsair is sticking with a pair of SP120L fans to provide airflow for the H75. These feature seven steeply angled and wide fan blades and come in black and grey to match the pump unit. PWM functionality is supported, with a Y-cable also supplied so that both can be controlled via a single header. It’s good to see two fans bundled with a unit that’s comparatively quite cheap, as a push-pull set-up will hopefully enable users to achieve better cooling with less noise.

The pump unit itself is relatively low profile. It has a copper microfin baseplate, but, unlike the h205, it has no interchangeable coloured rings. It’s not a major omission but it’s still a strange one given that both have the same pump unit design anyway. As ever, the pump will need its own 3-pin header connection to draw power from.

Installation is the same as it is with the h205, so we’ve few complaints here. The pump can actually be installed without tools, while the sliding pins on the Intel backplate make lining everything up very easy. However, one of the nuts in it began twisting within its socket when we tried to remove it – pliers make this an easy fix, but it’s still one reason why we’d prefer a metal backplate over the current plastic one.

Review: Corsair Hydro Series H75 — Cooling

Corsair’s burgeoning range of Hydro Series liquid coolers has become so varied that it can be difficult to pick out one particular model. The choices include 120mm, 240mm and 280mm options, and on top of that there are i-series models that tout Corsair Link integration.

There’s no shortage of choice in the closed-loop, liquid-cooler market, but the solution that stands out right now is the Hydro Series H75. Available for £65, this recent addition to the range touts a slim 25mm-thick radiator, two fans for use in a pull-push configuration and a renewed focus on low-noise operation.

Presented in typical Hydro Series packaging, the H75 arrives well-secured and bundled with all the parts needed for mounting on any recent Intel or AMD socket. Retail availability is good — all of the popular UK outlets currently have stock — and, as has been the case with Corsair’s previous liquid coolers, a five-year warranty is included as standard.

What we like about the H75 package is that Corsair has gone back to basics. There are no unnecessarily frills, no additional software is required and you won’t find any flashy LEDs. The H75’s simple promise is to provide «effective and efficient liquid CPU cooling in a compact size.»

Compact is a word that’s now used regularly by enthusiast PCs, and the H75 appears to be well-suited to small-form-factor builds. The 120mm radiator is just 25mm thick, the CPU block — with integrated pump — is very low profile, and the rubber tubing connecting the two is flexible enough to work well in most chassis.

The build quality of these core components is good, though it’s worth noting that the CPU block doesn’t offer the coloured accent rings that are available to the larger h205. Customisation won’t be quite so simple, however the black-and-silver aesthetic is attractive enough. Corsair has done well to integrate the ceramic-bearing pump into such a slim block, and the underside offers a well-finished copper coldplate with a microfin design and pre-applied thermal paste.

Box contents include two SP120L fans — these are standard fare on most Hydro Series products — as well as mounting kits for Intel and AMD CPUs, a brief instruction manual and a Y-splitter cable. There’s no spare thermal paste, though, so subsequent installations will require you to source your own.

The black-and-grey fan colour scheme matches up nicely to the radiator and pump, and both fans use four-pin PWM connectors allowing for precise speed control via motherboard headers. The splitter cable allows the fans to be attached to one four-pin header, helping save clutter, though remember you will also need an available three-pin header to power the pump.

There’s hardly anything to it, and that’s a good thing. Installing the H75 on an Intel LGA1150 socket is a simple four-step process; attach the backplate to the rear of the motherboard using four provided standoffs; fix the radiator/fan assembly to a 120mm mount using the eight provided screws; mount the pump on the CPU socket via four thumbscrews; then hook-up the power cables and you’re good to go.

Experienced users would have the H75 installed in under 10 minutes and novices should have no trouble, either. Though this is a dual-fan solution, the relatively-thin radiator keeps size down to a reasonable level, ensuring the entire unit is compatible with most mainstream chassis. The only thing to be wary of is the plastic backplate: it isn’t the strongest and can wear quickly. One of our standoffs is now turning freely as the worn plastic is no longer able to hold it steady, though this doesn’t appear to have impacted performance.

In a nutshell, the Hydro Series H75 is shaping up to be the right cooler at the right time. We’re seeing an increasing number of vendors attempt to squeeze desktop-grade performance into smaller chassis, and we suspect the H75 will prove popular in Mini or Micro ATX builds.

Corsair 4000D Case Overview

Would you choose a dark or light case color for your next system? Most users tend to settle for the palette that is the least prone to soiling, but for some reason we are sure that the white case is the more pleasing option (original and eye-catching).

If you pair the Corsair 4000D with a couple of RGB fans, you’ll have a visually perfect PC.

In stores, the Corsair 4000D modification can be found in black and white. And no matter which one you choose, the quality of the materials and the tempered glass sidewall will remain the same.

Viewable case is almost 100% made of rough metal, pleasant to the touch (it is very durable). There are practically no plastic parts in the design. This is great news for those looking for a durable case that will last for years to come.

If you go to the official page of Corsair 4000D (by the way, we have a modification codenamed CC-

99-WW), you will surely be inspired by the bright backlight and rich package bundle of the device.

You shouldn’t flatter yourself, the creators have been publishing a variable assembly in product card for a long time, which can be implemented on the basis of one or another solution.

In reality, everything is simpler. The Corsair 4000D has no backlight, and the owner will have only two 120 mm AirGuide fans (front and rear).

Viewed case form factor — Mid-Tower. It is quite compact and not at all bulky, although quite heavy for the reasons already mentioned (the case is made of high-quality metal and glass).

At the top of the Corsair 4000D lives a removable dust filter, which is attached to the frame with magnets (an extremely popular solution these days), at the bottom there is another one (a miniature tray under the power supply).

Is there profile protection for snout Corsair 4000D? Certainly. And full-length (in the entire length of the front wall). It will be possible to gain access to the overall filter itself after dismantling the front panel (it is fixed with powerful latches, no screws are provided).

The fan slots are easily accessible in the same way.

Side panels (steel and glass) are fixed using the same latches, but additionally you have to unscrew a couple of screws.

Corsair 4000D inside

The Rapidroute cable management system (that’s the name we saw on the official page) is a source of special pride for the developers. This is the most that neither is backbone or even skeleton into which the wires are embedded (using Velcro and plastic clips).

The Corsair 4000D mid-tower case is the ideal base for a powerful gaming PC. It retails for less than $100.

The idea itself is good and, in general, necessary for a premium device, but it’s hardly possible to fit all the cables from the power supply into this very skeleton . Rapidroute nominal is crammed with wires (USB on the front panel, PC power / reset buttons, sound, etc.).

But this is not such a serious problem. The Corsair 4000D has enough free space and shaped holes for proper cable routing.

The Corsair 4000D supports a pair of 2.5″ SSDs and two 3.5″ HDDs. A basket is provided for them, which is divorced in the PSU compartment (if necessary, it can be removed).

Assembling the system in the Corsair 4000D is easy and comfortable. The case itself is quite compact, there is nothing superfluous inside, but all scenarios are thought out in advance, so the owner of the case can count on 100% implementation of the most daring ideas.

It is advisable to mark the closed CBO in the upper part of the Corsair 4000D, and we advise you to completely force the front panel with backlit fans. By the way, regular propellers are extremely quiet (they are connected to the motherboard via a 3-pin connector).


The Corsair 4000D can be scolded for its lack of backlight, no fan controller, and only two 120mm propellers. But with these flaws really put up with (or fix them yourself), it is much more important that the asset snow white has a lot of other original features.

Corsair 4000D is made of strong and reliable steel, there is a tempered glass sidewall. Assembly scripts are carefully thought out, the process is a pleasure. Well, the design of the device is something fantastic. We have not seen such an aesthetically attractive case for a long time.

The Corsair 4000D mid-tower case is the ideal base for a powerful gaming PC.
