Corsair Hydro H75 Review

Performance Analysis

The full speed delta T result on the LGA1155 system of 40°C is very respectable, as it's on par with the H80i's full speed result too, despite the thinner radiator and tubing. However, noise from the two fans is very loud here, almost unbearably so. Both the Phanteks PH-TC14PE and Noctua NH-D14 are able to achieve the same or better with lower noise levels. Thankfully, the H75 delta T only increases by 2°C using PWM, which results in a much quieter operation that's well worth the small thermal sacrifice.


The H75 also does well on the LGA2011 system. On this set-up, which runs much hotter than the LGA1155 one, the thicker radiator on the H80i does allow it to outperform the H75 by 2°C, but even so the H75 still keeps up with the bulkier and more expensive SilverStone TD03 with a 47°C delta T. The PWM result of 51°C is also acceptable given the noise output, though bigger coolers like the H100i and Noctua NH-D14 perform better with less noise.

Conclusion

If you'll excuse the pun, the cooler market is now rather flooded with all-in-one liquid cooling solutions. Even limiting ourselves to Corsair we see a rather large selection, but the company does tend to have an advantage over the competition with such products. The easy installation, relatively low space requirements and all-round decent thermal performance mean that if you need a closed-loop cooler for under £70 the H75 should be your choice. If you have the room, however, large air coolers like the Noctua NH-D14 and Phanteks PH-TC14PE are still excellent alternatives.
