Final Thoughts, Pricing, Conclusion
Our experience with the H70 had many high points, but there were a few minor issues that might turn off some enthusiasts. The first minor issue I noticed was the additional noise from the fans. We tried the fans with and without the voltage regulator cables, but the different in fan speeds was very minimal and it didn’t seem to help with the extra noise we heard. Our test case actually had four 120mm fans running between 800 and 2,000 RPM and another 200mm exhaust fan running at 800 RPM during testing, which also contributed to the extra fan noise.
An easy way for Corsair to decrease fan speeds would have been to provide a simple fan controller that allowed users to manually configure the fans used with this unit. The ability to manually configure the system, possibly with third-party software, would have definitely been better than just leaving us with barely any options other than swapping out voltage regulation cables for the fans.
There were three key factors that helped the H70 increase its performance over its competitors. The first is easy and obvious to spot – the dual push-pull fan configuration. The second is a large copper cold plate that was milled well and provide good contact with the CPU. Finally, the 50mm radiator added a higher heat-exchanging capacity over the smaller radiators used with the H50, Vantage A.L.C. and ECO A.L.C.
We’d like to thank Corsair for providing the Hydro Series H70 for our evaluation today. Their second attempt at a self-contained CPU watercooling system really expanded on Asetek’s original technology and the addition of a push-pull fan configuration is exactly what enthusiasts were asking for after their initial experiences with the H50. As with all of their products, Corsair really put their signature on the H70 and created an original product that will give enthusiasts more flexibility for overclocking and modding than they would have with today’s bulky air-cooled heatsinks.
- Push-pull fan configuration
- 50mm radiator
- Excellent performance under load conditions
- A little more expensive than competitors and H50
- No manual options for configuring fans or system itself
- Extra software for monitoring system would be beneficial
