Corsair H70 High-Performance Hydro CPU Cooler Review

Corsair's H50 sealed processor water cooling system has been a favorite among many. While it is a very solid product there was nothing truly stellar about the H50. Corsair is back to the design table today with its new H70 sealed processor cooling system. How does it perform and is it worth the upgrade? Should be at least 20 better.

Corsair H70

As mentioned before the H70 is not Corsair’s first attempt at a water cooling unit and in many ways this shows. Where the Nautilus was an external unit with one fan that couldn’t be replaced easily, the H70 is an internal unit that supports up to two fans that can easily be swapped out. The unit comes completely filled and sealed unlike the Nautilus 500 that required you to use your own water. The list goes on and on but suffice it to say that Corsair has taken a good concept and made it better.

Installation & Contact

Installing the H70 was a bit tricky and having a third hand would have definitely helped. Installing the fan and radiator first was a bit tricky since the fan is not attached to the radiator and you must thread a screw through your case, the fan and finally into the radiator. Not a huge deal but a bit tricky so take your time.

Probably the trickiest part was attaching the H70 to the CPU. After first installing the retention ring to the board you have to slip the head of the H70 under the clamps on the ring twist to line up the latches and then tighten the four screws to hold it in place. The end result is a strong bond but trying to remove the head without smearing the paste is difficult as you’ll see.

The nice thing is that since we are dealing with water cooling the is plenty of space available for your RAM and even in this worst case scenario I have pictured, the first RAM slot is still available.

As mentioned, the base is a bit smeared from the removal/installation process but otherwise we can see a very good contact patch with the CPU.
