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 Frostytech tests heatsinks with thermal values that represent the upper limits of both existing CPU families. With a 150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal test platform, the NPH-1000 heatsink yielded a rise above ambient temperature of 29.3°C (47.5dBA) at the fans' stock speed.

Next, the NPH-1000 heatsink was tested with an 85W heat load; akin to a Core 2 Duo processor. With a lower degree of heat for the NPH-1000 to disperse to the surrounding environment, the cooler was able to keep up with a nice result of 16.8°C over ambient.

On both AMD and Intel test platforms the nPowertek NPH-1000 heatsink handled itself well, placing about middle of the pack. On the AMD front at least, the NPH-1000 heatsink outperforms the NPH-Big K8 model. However, in both situations there are a handful of other heatsinks which are able to perform cooler, with less noise output.
