Prolima Megahalems: A Mega Nehalem Cooler
 

The Prolimatech Megahalems delivered a championship performance, no matter how much airflow was supplied by the fan. It performed similarly to the Thermalright HR-01 Plus in a low airflow environment, but did 3°C better with high airflow, making it an all-around superior cooler.

We were unsure whether a heatsink with tight fin spacing would do as well with low airflow, but the Megahalems had just the right design to make it work. There's little doubt that the extremely secure mounting system also plays a big role in its success. We appreciate its simplicity as well — most of the process is tool-less except for the final step which requires a screwdriver. The mounting components are also rather large making them harder to misplace. Only the lack of support for AMD processors is a bit disappointing, though this may come in the future.
