I will be testing the Corsair Hydro H70 using the following hardware:

Intel Core i5-2500K
OCZ Flex EX PC3-17000 2 x 4GB
Sparkle GTS 250 Video Card
BFG Tech MX 550W Modular PSU
OCZ Vertex 2 50GB SSD
NZXT Premium Cables
Corsair Obsidian 800D
Optical drive
Windows 7 Home Premium 64-bit

Following the installation instructions, the first thing I did was prepare the retention ring. Since I will be installing this on a Socket 1155 system, I used the appropriate 1156 (backwards compatible with 1155) retention ring and accompanying brackets and screws. I also prepped the backplate using the correct inserts and adhesive pads.

The overall process here is pretty easy but be sure to keep a close eye on the instructions so you don't install something backwards or use the wrong hardware.

With the backplate prepped, the next step is to slide it through the back of the board and attach the retention ring. If you look closely at the photo above, you will notice that the backplate sits crooked on the back of the board. Although it looks strange, this is perfectly normal as I double checked that I used the correct mounting holes.

Corsair points out that you should only loosely tighten the retention ring to the backplate. The reason for this is that you don't actually mount the water block just yet - that is done once you mount the radiator inside your case.

I snapped these pics for reference to show you how the fans attach to the radiator and how thick the overall assembly is. Corsair suggests that you install the fans in a push-pull configuration and pull cool air from outside of the case, through the radiator and dump it into your chassis. I realize that most of you would disagree with this as it would heat up the air inside your case, but since Corsair suggests it, that is how I will be installing the unit.

Since I am using the 800D chassis, I opted to mount the radiator assembly to the roof of the chassis in the middle fan slot, thus still allowing me to use the rear 140mm exhaust fan. Corsair points out that the orientation of the radiator shouldn't make a difference in the performance of the cooler.

Depending on where you decide to mount the radiator, you may or may not want an extra pair of hands. It took me a bit of time to get the assembly mounted in the top of the case by myself but as you can see from the photo above, everything turned out great.

Mounting the block is an easy task once you have the radiator installed. Simply slide the water block under the retention ring, twist it so that the teeth line up with those on the ring, then tighten the ring down using the four screws. It's best to tighten in a crisscross pattern until all screws are tight.

Let's move ahead and put the Hydro H70 to the test!
