FrostyTech Mk.II Synthetic Thermal 
            Heatsink Test Results 
             
            Intel 
            Pentium D / Extreme Edition & Quad Core class heatsinks tested 
            at 150W Intel Core 2 Duo / Pentium 4 / 
            Celeron class heatsinks tested at 85W Results based on readings from a 30x30mm copper 
            interface die with 150W and 85W heat loads applied on the LGA775 
            version of the Mk.II Test Platform. Temperature results listed for 
            each heatsink were calculated by determining the rise over ambient 
            temperatures at time of test. Information on Frostytech's test 
            methodology is available here. |

    | *heatsinks are ranked according to the 150w thermal 
      test results column (rise over ambient temp.). low temperatures with low 
      noise levels are considered best. for reference heatsinks with 
      variable-speed fans, only the high speed (12v) fan test result is included 
      in the comparison sheet; more detailed results reside in each specific 
      heatsink review. | 
Frostytech tests 
with two thermal values that represent the upper limits of existing Intel CPU 
families, 150W and 85W.
With a 
150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic 
thermal test platform first, the Prolimatech Megahalems heatsink maintains an 
excellent result of just 15.0°C over ambient with the 80CFM fan (53.0dBA noise). 
Switching to the 50CFM fan results in a rise over ambient temperature of just 
16.8°C over ambient.
Prolimatech's Megahalems heatsink was then tested with an 
85W heat load. In this test the Megahalems easily maintained an extremely low 
temperature result of 9.2°C over ambient with the 80CFM fan and 10.2°C over 
ambient with the 50CFM fan. 
Fantastically low CPU die temperatures 
really...
On a side note, while Frostytech tests with a maximum 
150W heat load, it was surprising how cool the entire test setup ran. I won't 
hazard a guess, but I expect the Megahalems could easily handle loads of 220W or 
more...
Prolimatech's Megahalems heatsink is arguably one of 
the best heatsinks available on the market for Intel socket 775 processor and 
AMD socket AM2 chips, and well worth the modest $60 investment. The cooler is 
well made, the mounting system refreshingly uncomplicated and robust, and it 
cools very well. Build quality is first rate.
On the 
Intel synthetic thermal test platform especially, the Megahalems heatsink ranked 
in with the second coolest results Frostytech has seen to date! Highly 
recommended for those whose PC's can accommodate the 160mm height, and who 
aren't put off by the heatsink's 790gram weight.
