Conclusion


There’s a lot we can say about the H70 and unlike some other closed system water cooling units, it just flat out impressed us. We have seen time and again some of the supposedly “cutting edge” products in this field fall on their faces the second it came to dissipating heat from an overclocked i7. But not the H70. In our minds, Corsair has a real winner on their hands and they have every reason to market it to their hearts content.

One of the main points which should be emphasized is the fact that Corsair’s H70 is the highest performing closed loop system we have ever tested. It accomplishes this through spot on engineering and what seems like an obsession for Corsair: getting it right the first time. The fact that cooling potential of this magnitude can be packed into a unit that fits snugly on a single 120mm fan mount continues to amaze us. Speaking of mounting, it is also great to see that the installation process for the H70 has been vastly improved over its predecessor, the H50.

There are however some minor concerns which rear their ugly heads now and then. One of the main reasons for the performance we saw is the sumo-like radiator which led to Corsair specifying high speed fans. These two fans perform extremely well in their duties to push sufficient air through the radiator’s fins but they make an awful racket. Our sound level testing didn’t show this but at full speed they scream like banshees. Luckily, Corsair ships a resistor which will of course lower performance but it may also save your sanity.

Another issue with the H70 is the fact that in Corsair’s recommended setup it exhausts hot air directly into the enclosure it is installed into. This runs contrary to the usual convention of “cool air in, hot air out” which most cases are designed around and as we saw in our testing: the temperature increase is significant. If you have good airflow within your case, this won’t be of any concern but we still recommend taking the slight hit in overall CPU cooling performance and flip the H70 around so it exhausts hot air outside the case.

While it may command a price premium over some of the best air coolers on the market, we feel like the H70’s performance more than warrants its price. The use of a double-thickness radiator and a highly compact water block / pump combination usually results in high temperatures but that hasn’t happened here. Instead, through engineering excellence Corsair has designed what is currently one of the best (if not THE best) closed loop water cooling systems on the market. As such, the H70 wins our Dam Good and Dam Good Innovation awards.


Pros:

- Improved Installation over the H50
- Absolutely excellent performance
- Compact compared to custom water cooling setups
- AMD and Intel stock installation equipment included
- TWO good fans included
- Silent Pump
- 50mm Thick Radiator
- Included resistors to lower fan speed


Cons:

- Noisy stock fans at full speed
- Corsair still recommends exhaust IN setup
- Large size compared to some other units
