Corsair H75 Review
Category : Watercooling
Published by Christian Ney on 10.12.13
Corsair, famous for its quality memory, PSU and recently, PC cases and gaming peripherals, have been also making quite a push in the All-in-One water cooling market and some of its Hydro series coolers have been quite impressive. Today, we are looking at the latest Corsair Hydro H75 series AIO water cooler which stands out with its impressive manufacturing quality as well as new Asetek design. We will certainly try to find out if it has what it takes to compete in the quite crowded AIO water cooling market.

Corsair's Hydro Series H75 provides effective and efficient liquid CPU cooling in a compact size and thanks to the 120mm radiator which has a thickness of only 25mm and paired with standard diameter, kink-resistant tubing makes it compatible even with smaller cases and tighter spaces. It packs dual SP120L 120mm fans with support for PWM motherboard fan headers, which allows automatic control of fan speeds based on CPU temperature. It also feature a tool-free mounting system with support for most, if not all, recent Intel and AMD socket CPUs.
The Corsair Hydro Series H75 features a copper microfin coldplate and high-quality ceramic bearing pump which should provide reliable, low-noise heat transfer away from your CPU, according to Corsair. Like all Hydro Series liquid CPU coolers, Hydro Series H75 is completely self-contained and never needs filling or maintenance.
The Hydro Series H75 is actually Corsair's eight Hydro cooler and based on a new Asetek design. The Hydro H75 is a Corsair product but designed and manufactured by Asetek.

As you can see from the picture as well as we could see from our first look, the manufacturing quality of the Hydro H75 is quite impressive and Corsair decided to go for high quality materials, making the Hydro H75 much better than the Hydro H90, which we previously had a chance to see. It packs a standard 120x25mm radiator made from aluminium, features a copper coldplate with high-quality ceramic bearing pump which should be silent. Although the radiator design is quite standard, since there is not much to do there, Corsair decided to use the new, and quite good looking, design for the pump/base part. The fans also come with a new design that works quite well with the rest of the Hydro H75 AIO cooler. Corsair decided to pair the Hydro H75 with two 120x25mm SP120L fans, which are definitely high-quality looking fans with grey wings.

The packaging is quite standard for an all-in-one water cooling setup as you get the AIO unit, two fans, manual and the mounting kit. Corsair bundles the Hydro H75 with two toolless mounting kits, one for AMD and one for Intel-based systems. Corsair also threw in a Y-split fan cable and although the thermal paste is not supplied, it has been pre-applied to the base, making the installation quite a breeze even for an average computer user.
Corsair has a five year warranty backing the Hydro H75 AIO water cooler and while three years were quite standard earlier, we lately see more and more products with five year warranty.

The installation procedure is quite easy and practical. It is pretty much self explanatory and since we are looking at toolless mounting design, it is surprisingly easy and should not be a problem even for less experienced users. The design is not completely toolless as you will still need a screwdriver in order to mount the fans. The pressure on the CPU is very good and since the base/pump is a low profile design there should not be any clearance issues as even tubing can be moved in any direction without worry of blocking or leaking.

Absolute Performance
Temperatures
7 V
To measure cooling capacity we took temperatures in idle and load with the fans at 7 and 12 V. The idle temperature represents the lowest temperature hit by the processor package after 10 minutes in idle. The load temperature is the highest temperature hit by the processor package after one pass of wPrime v2.10. The wPrime test takes 4 minutes and puts load on all 8 threads. Room temperature is 25°C.
12 V
Fan Speeds
Fan speeds (RPM) at 7 and 12 V.
Noise Levels
Decibel meter (Voltcraft SL-200) has been placed 1 meter away from the cooler. Measurements are conducted in a quiet room, where there are no other noise source. 32 dBA is the lowest we can get in our room. Also here the measurements are conducted at 7 and 12 V.
Watercooling Pump
Above the Water cooling pump speed (RPM) at 7 and 12 V. Below the noise levels of the Water cooling pump at 7 and 12 V (pump only, fans are off).

PWM Performance
Temperatures
At this point we plugged the fan(s) to the motherboard CPU fan header and let the motherboard take care of fan speeds. In other words the motherboard will ajust the fan speed via PWM signal according to CPU temperature. The idle temperature is the lowest temperature hit by the processor package after 10 minutes idle. The load temperature is the highest temperature hit by the processor package after one pass of wPrime v2.10. The wPrime test takes 4 minutes puts load on all 8 threads. Room temperature is 25°C.
Fan Speeds
Values are in RPM, we took the lowest speed hit by the fan(s) in idle and the highest under load.
Noise Levels
Decibel meter (Voltcraft SL-200) has been placed 1 meter away from the cooler. Measurements are conducted in a quiet room, where there are no other noise source. 32 dBA is the lowest we can get in our room. Also here the measurements are conducted at lowest and highest fan speeds in idle and under load respectively.

Conclusion
| General | + | - | |
| Overall, the Corsair Hydro H75 Series is a very good product with exceptional quality, especially considering that we did not like the manufacturing quality on the Hydro H90 that we had a chance to see earlier. It also offers a really good cooling capacity while maintaining silent operation and good performance. |

| Installation | + | - | |
| The installation could not be more simpler, as it is very easy, practical and pretty straightforward. With two included Intel and AMD mounting toolless systems, it should be quite easy even for less technical users. The only drawback that we could find is that it is unfortunately not compatible with LGA 775 socket, which is not a great deal as these are quite old CPUs but still. The thermal paste is pre-applied and although we would like to see it included in the box, this makes the installation much easier for an average user. |

| Performance | + | - | |
| The Corsair Hydro H75 series has a very good cooling performance in every scenario, including 7V and 12V as well as PWM mode. We tested the Hydro H75 in push and pull configuration since Corsair provided two fans with the Hydro H75. The performance did not change a bit with two or single fan configuration and while the Pull&Push is definitely a bit louder, it is still very silent in PWM mode. | - Cooling performances | ||
| Noise Levels | + | - | |
| While the pump on the Hydro H90 was silent but audible, the pump on the Corsair Hydro H75 is even more impressive with almost noiseless operation. The entire Hydro H75 AIO setup is noiseless most of the time and the noise does not climb any higher when CPU is under heavy load in PWM mode. |

| Recommendation / Price | + | - | |
| With all this in mind, we simply have no choice but to recommend the Corsair Hydro H75 series AIO water cooler, and we certainly do it with a great pleasure. With price of 66 Euros, it is a bit more expensive than the competition but considering great performance which is almost noiseless even under load as well as the exceptional manufacturing quality and two fans, the price does not seem that much and it is definitely justified. | - Price | ||
| Rating | |||
| We gave the Hydro H75 from Corsair 4.5 out of 5 stars. | |||
