Pros: Provides much better temps at higher clocks under full load. Easy to install. No need to piece together multiple parts.

Cons: Idle temps seem to sit higher than my old Hyper 212+. Operates better on intake instead of exhaust, not good if you have a GPU that dumps in the case.

I got this cooler from a guy at a LAN event I went to. He had been trying to get rid of it for a while now and it had just been sitting around in a box not doing anything but collecting dust. After chatting with him for a while and explaining my interest in water cooling but lacking any real funds to do so, he gave it to me since he would rather it have some use instead of doing nothing. And so it came to be that I had ventured into liquid cooling but not without some hiccups along the way.

While the H70 was, at it's time, the top-of-the-line AIO cooling solution, it was far from being the best cooling solution, period. At high clocks and full load it kept temps down much better than my Hyper 212+ on my i7-920 but when it came to idle temps it didn't really do much better and seemed to actually increase my temps by about 5 degrees. It did perform quieter than the air setup simply because I could have the fans blowing at slower RPMs and get better temps when dealing with high load situations but the higher idle temps left my fans running fast at idle than when the 212+ was cooling.

The Corsair H70 is a great pick for people that can get it cheaply but I wouldn't buy it if you need something that is going to be cooling more powerful chips or if you need better idle temps with lower RPMs.


I find my H70 to be a disappointment. It is easily beaten by many a cheaper and quieter coolers and the only way to have it cool better is by modding it.
My H70 was fantastic, crazy cool temps with UK3000. I use mine on my gpu now, my oc 580 can have 19c startups .... or lower but I only have pic proof for 19c but ive seen 17c before on very very cold mornings.

Mine was a launch edition but way back then they came with TWO FANS. Convinced my parents to get one for their new pc and it only came with no fans.
