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 assembly is easy to put together. Bolts go into the back of the motherboard through the backplate and some plastic spacers. Mounting clips are attached to the ends of the bolts with nuts, the heatsink is placed onto the CPU, and a bar goes over its base and is secured to the clips with spring-loaded screws.

As the heatsink is only attached via two screws, it's very easy to remove. The crossbar also delivers significant pressure directly over the base, pinning it to the CPU heatspreader with considerable force.

The HE02 mounted on our test platform with a pair of our reference 140 mm fans, Noctua NF-P14's. In this orientation, the longer portions of the heatsink face the DIMM and expansion slots.

The edge of the HE02 just clears the first expansion slot of our test board.

Due to the HE02's width, the fans hang over both the memory slots and VRM heatsink, forcing the fans into unusually high positions. Clearance below the bottom fin was 49 mm.

On our setup we encountered an issue with the fins clanging (they seemed to be a bit loose), most notably when two fans were mounted and running at high speed. Adding some adhesive foam to the fan corners helped somewhat.
