FrostyTech Mk.II Synthetic Thermal Heatsink Test Results
AMD Athlon64 / FX / X2 & Sempron class heatsinks
Results based on readings from a 38x38mm copper interface die with 125W heat load on the K8 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.

125w thermal test (°c) noise level (dba)
*heatsinks are ranked according to the 125w 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.

With a 125W heat load applied by the FrostyTech synthetic thermal test platform, the nPowerTek NPH-K8 Big heatsink yields a rise above ambient temperature of 27.8°C, with 54.0 dBA noise generated. The results shown here are valid only with the 120mm Martech D712025125Z2N fan we used; if you swap it out for another unit in an effort to produce less noise the thermal values may change.

On the whole, the thermal performance of the nPowerTek NPH-K8 Big heatsink is slightly lower than the stock socket 393 AVC Z7U3301001 heatsink (a difference of 3.2°C) and better than the old standard socket 754 Ajigo MF043-044 heatsink (a difference of 7.2°C).

The TTIC nPowerTek NPH-K8 Big is a good mid-level AMD K8 heatsink, situated almost at the dead center of this reference list in fact. Noise levels are pretty moderate too, and comparable to heatsinks which run warmer. Unfortunately, this version of the product is not socket AM2 compatible.

Given the opportunity, there are three changes FrostyTech would make to this heatsink. First we would alter the aluminum mounting bracket so it is not flush with the base of the copper heat column. Second, those aluminum fins would get a nice nickel plating allowing them to be soldered directly to the copper column, and ensuring a better thermal interface. Lastly, we'd add some texture and geometry to the straight flat aluminum fins to enhance heat transfer. nPowerTek is certainly on the right path here, but the NPH-K8 Big heatsink still feels like it could do well with a few additional refinements....
