FrostyTech.com Mk.II Synthetic Thermal Heatsink Test Results
Results based on readings from a 38x38mm copper interface die with 125W heat load on the Mk.II Test Platform. Thermal Test values for each heatsink were calculated by determining the rise over ambient temperature 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.

At its highest fan speed of 5400RPM, the AVC Z7UB301 heatsink performs very well indeed. According to the thermal test results from the FrostyTech Mk.II Synthetic Test Platform which applies a 125W heat load to the heatsink, the AVC Z7UB301 maintained a rise above ambient temperature of 24.6°C at its best fan speed. The noise level was nearly 60 dBA in that case however.

When running with a more conservative fan speed, noise levels dropped to about 44 dBA and temperatures rose to a rise above ambient temp. of 32.6°C - pretty good actually. The temperature sensitive fan utilized on the AVC Z7UB301 heatsink certainly gives it the potential to be both a great performing heatsink and a lower noise one as well.

Considering these results, it is clear that AMD has provided socket 754/939/940 Athlon64 users with very capable heatsink. The AVC Z7UB301 is designed to cool only as much as necessary, which leaves us wishing there were a way to manually control the fan speed. In any case, it is comforting to note that there are quite a few third-party heatsinks which perform poorer than the AMD reference AVC Z7UB301 heatsink at its quietest, and most surprisingly with higher noise levels too.
