Prolimatech Megahalems Rev. C CPU Cooler Review

Firstly we had to position 4 rivet nuts through the specific mounting holes in our backplate and fasten them in place with rubber O-rings. This kept the backplate secure while we prepared the rest of the cooler for installation.

4 double-ended stand-offs are screwed into the rivet nuts which emerge from behind the motherboard.

The cooler is fastening in position by a sturdy cross-bar which screws into the pair of metal retention bars.

When installed, the Megahalems Rev. C was held very securely in place. Prolimatech’s cooler mounting method is excellent, something that other CPU cooler manufacturers could really learn from. Their fan installation method on the other hand is continually frustrating. Small metal fan clips which aren’t particularly sturdy and limit fan choice really should have been abolished years ago.

One slight positive of the annoying fan installation method is that the height of the fan is user-definable resulting in a variable amount of RAM clearance. On our MSI P67A-GD65 motherboard the Megahalems overhung the first RAM slot but didn’t quite hit the second.

Using a pair of 140mm fans, the Megahalems Rev. C dictates a good amount of clearance inside any chassis. Our NZXT Phantom offers plenty of internal room, but other chassis’ may be slightly more reluctant to fit this CPU cooler and fan combination.
