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.

From the results of testing the Dynatron A41 heatsink on the FrostyTech Mk.II test platform with a 125W heat load, we can see that this socket 754/939 AMD Athlon64 heatsink handles the job very well for its compact size. Both the Zalman CNPS7000-Cu and CNPS7000-Cu heatsinks, which flank the A41's 30.3°C rise above ambient temperature result, are considerably larger and heavier.

Dynatron have built a good mid-level performing heatsink that operates very well for its small size, and 342 gram mass. This heatsink would be fine for use in a 2U server or desktop Athlon64 computer. The 4300RPM fan generates 56dBA in our tests, meaning this is certainly not a low noise heatsink. If ultra-low noise levels are one of the major decision factors, there are other heatsinks to choose from. If moderate-to-high noise levels with great cooling performance and compact size are what is needed, the skived aluminum Dynatron A41 heatsink fulfills that role admirably.
