Prolimatech Megahalems Revision C CPU Cooler Review

In order to provide you with the most professional and accurate reviews, we are using the following equipment to test the performance of coolers. The system automatically calculates the Delta T temperature, which is the difference between the ambient temperature and the temperature at the top of the thermal core. We test each cooler with the included thermal grease.

  • Custom copper thermal core with automatic power controls
  • Watlow heat generation rods
  • PT100 temperature sensors
  • Lutron DW-6091 Power Analyzer
  • SL-5868P digital sound level meter
  • CompuLAB interface
  • MyPClab thermal interface
  • Custom calibration box
  • Custom software

More information about our testing equipment and methodology can be found in this article.

The latest revision of Prolimatech’s Megahalems did not make it at the top of our charts; at least not with the 120mm fans we used. More powerful fans could improve the cooling performance of the massive cooler slightly, allowing it to outpace the competition. At the same time however, the acoustics performance of this particular model is considerably superior to that of other coolers offering similar thermal performance, even with two 120mm 1600RPM fans installed.
