Installation is 99% the same for the two, the only difference being mounting the radiator. Let's take a look at the steps involved to install the Kraken CPU cooler.
The first step is to install the threaded metal spacers into the appropriate holes in the cooler backplate. The backplate is marked for each socket so you simple push the threaded insert into the hole until its completely seated as shown above.
The next step is to adhere the included adhesive pads to each side of the cooler backplate. These will hold the backplate to the motherboard to facilitate easier installation.
Here we have the completed backplate assembly mounted to the backside of the motherboard.
There are a pair of clips that need to be installed to each leg of the block retainer. There is an upper and lower piece. The hole is offset so you need to install it according to the socket your motherboard has.
Once the retainer assembly is completed the 4 mounting screws snap into the plastic clips and the clips act as retainers. They keep the screws from falling out. Once you've got the retainer positioned on the pump/block assembly there is another plastic ring clip that mounts from the bottom, essentially sandwiching the block between itself and the upper retainer. Altogether this makes a very simple to install setup. The retainer is secured to the block, the screws are secured to the retainer and the backplate is secured to the motherboard. NZXT really put a lot of thought into the mounting setup for the Kraken series to make it as easy to install as possible.
The radiators are particularly easy to mount due to the length of the tubing. 400mm (16") is much longer than the typical AiO cooler's tubing you'll currently find on the market. Here we have each cooler installed into our Cooler Master HAF XB which has plenty of room for a 140mm or 240mm radiator up front.
Now that the cooler is installed let's check out the software.
