Installing Thermaltake's NiC-L32 CPU Cooler
Thermaltake’s NiC-L32 CPU cooler uses two large mounting rings in a sandwich design. It's easiest to install with the motherboard removed from the case.
Foam is supposed to prevent short-circuits on the base plate, but the legs of some capacitors appear to poke all the way through. Just to prove that they could be shortened without special tools, I trimmed the longer leads with a pair of fingernail clippers.
The screws seen in the above photo engage top-side standoffs in the photo below. Each standoff has a foam ring on one side to protect the surface of the motherboard. Screws then attach the top-side mounting ring to the standoffs.
A large dab of paste in the middle makes a large circle about the size of the CPU heat speader. I like to add a smear next to each corner to maximize contact area.
Also notice the orientation of the top mounting ring. The two threaded nubs act as spacers to prevent over-tightening of the next piece in the installation puzzle.
The NiC-L32’s heat sink is secured with a cross-brace, which uses two shoulder screws to connect to the previously-described top ring. A diagram is provided in the cooler’s installation instructions.
