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.

intel's processors have a smaller integrated heat spreader than the AMD K8 CPU series. In practical terms this means there is less surface area in contact with the base of the Nexus HOC-9000 heatsink. Given the 2mm spacing between each of the four 8mm diameter heatpipes on the base plate of the HOC-9000 heatsink, it's not unsurprising that thermal test results have slipped as all four heatpipes aren't making 100% contact with the CPU. Let's go over the results.

With a 150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal test platform, the Nexus HOC-9000 heatsink maintains a temperature of 23.6°C over ambient (43.0 dBA noise / full fan speed).

The HOC-9000 was then tested with a 85W heat load, at the same default fan speed, resulting in a 14.6°C rise over ambient temperature. Both results are quite good, but not excellent.

In the next round of synthetic thermal testing the HOC-9000 heatsink had its fan speed dropped to 800RPM. The test resulted in temperatures of 35.1°C and 22.2°C over ambient for the 150W and 85W heat loads respectively. Noise levels were whisper quiet at 30.4dBA.

Examining the test data leads us to a couple conclusions; for starters the Nexus HOC-9000 heatsink has a natural advantage cooling AMD processors. The wide spacing of the heatpipes on the base of the HOC-9000 give it a slight handicap on Intel chips, most notably when the fan is running at the super quiet speed of 800RPM. Ultimately the Nexus HOC-9000 stumbles a bit with its attempt at 'direct touch heatpipes', yet it remains a perfectly good AMD/Intel heatsink. Just remember that larger diameter heatpipes don't automatically mean better overall performance.
