Scythe Mugen 4 CPU Cooler: Scythe Strikes Back

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 biggest change from Scythe's previous heatsinks is the mounting system which has undergone a much needed update. The new scheme is essentially the same as the almost ubiquitous system used by most modern high-end coolers.

Mounting clips are secured to a backplate with plastic spacers in-between to prevent shorts and to bring them up to the appropriate height.

A thick metal crossbeam over the base is bolted to the clips. This exerts pressure down onto the processor from above.

Fully installed on our LGA1366 test platform.

The fan blocked off one of the memory slots but it's usable as long as the DIMM height is kept at a minimum. There's about 38 mm of clearance underneath the bottom fin, more than enough to accommodate the VRM heatsinks on most boards.

Most of the thermal compound was pushed out to the edges leaving only a faint imprint at the center. This is a sign of excellent contact.
