The most critical aspect of installation is that the heatsink be securely mounted. A firm mating results in good contact between the heatsink's base and the CPU heatspreader and more efficient heat conduction. Ideally it should also be a simple procedure with the user having to handle as few pieces of hardware as possible.

The mounting hardware includes a multi-socket back plate and a dual head 3-pin fan adapter.

The mounting system is similar to those employed by Noctua and Prolimatech. A metal plate is placed at the back, long screws are pushed through the appropriate holes and secured to a pair of mounting clips with nuts and plastic spacers on the other side. A metal bar with spring-loaded bolts goes across the base of the heatsink and screws into the clips.

On AMD boards, four-way mounting is accomplished by combining the AMD and Intel clips with small screws.

The ends of the fan isolators have to be stretched and rotated to fit between fins on the heatsink. We were concerned that the sharp metal edges would eventually cut into them but after several fan swaps, they were no worse for wear. Note: it is much easier to attach them to the fan first.

The isolators have to be pulled toward the center of the heatsink as well because the stock fans lack 140 mm mounting holes.

Installed on our Asus P6X58D Premium motherboard. The intake fan hung partially over the first DIMM slot; there was enough clearance underneath for a bare stick of memory with only 1~2 mm to spare.
