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.

Noise Level (dBA)
*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 processors vary in power output between single and multi-core models, so FrostyTech tests heatsinks with two thermal loads that represent the upper limit of each CPU family, 150W and 85W. With a 150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal test platform, the Noctua NH-U12P heatsink maintains a temperature of 21.3°C over ambient, with 40.7dBA noise. Noctua's NH-U12P heatsink was then tested with a 85W heat load, resulting in a low 13.4°C rise over ambient temperature.

The black fan speed reducer is up first, and as we already know it keeps noise to about 34.6dBA. At this fan speed on the 150W synthetic test platform, the Noctua NH-U12P heatsink held steady at 23.4°C over ambient. Next was the 85W head load test, where temperatures stayed at 14.8°C over ambient. For the blue fan speed reducer, the 150W and 85W tests saw temperature rise to 25.3°C and 14.9°C respectively. Noise levels remained constant at 32.1dBA.

These results reaffirm Noctua's position as a maker of great low noise heatsinks for Intel and AMD processors.

The Noctua NH-U12P heatsink in particular, with its NF-P12 fan, runs very quiet at full speed and maintains temperatures that keep it in with the top 10 AMD & Intel heatsinks.

Noctua's NH-U12P is certainly a big heatsink, and that will keep it out of a lot of compact PC chassis which could otherwise use a good quiet heatsink. That's the nature of the beast I suppose. From what we've seen here, it is possible to drastically reduce the noise output with the two supplied fan speed reducers. However, I'd stick to the black one if you find 40dBA to loud; it gives the best reduction in noise with the least impact to cooling capacity on either AMD or Intel platforms. The blue speed reducer will make things quieter, but temperatures rose by an average of 4-5°C as a result. In any case, Noctua have produced a very nice low noise heatsink here. Recommended.
