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.

The heat output from Intel processors varies widely between single and multi-core processors, so we've settled on two values which represent the upper limit (150W and 85W) of both existing CPU families.

With a 150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal test platform, the Akasa EVO 120 heatsink maintains a excellent rise above ambient temperature of 24.3°C. To achieve this result, there was 52.9 dBA noise from the 120mm fan spinning at its full speed of 2000RPM. The CPU equivalents of this test would be an Intel Pentium D / Extreme Edition or Core 2 Quad class chip. At the much quieter fan speed of 1000RPM, the synthetic CPU temperature rose by only a few degrees to 29.0°C (37.6 dBA) over ambient.

The Akasa EVO 120 heatsink was next tested with the reduced heat load of 85W. In this case the heatsink produced a 14.1°C rise over ambient at full fan speed. When the fan speed is reduced to quiet mode (1000RPM), the EVO 120 heatsink yields a temperature of 17.6°C over ambient.

On the whole, the thermal performance of the Akasa EVO 120 heatsink is excellent. This is a very capable low noise heatsink when running with a reduced fan speed in particular. Thermal performance increases when the fan speed is set at default setting naturally, but under these conditions the Akasa EVO 120 heatsink is somewhat audible, with a noise level of 52.9 dBA. No matter how you cut it though, the Akasa EVO 120 heatsink is a very competent choice for Intel socket 775 and AMD Athlon64 platforms (939/AM2).
