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 amd k8 version of
the frostytech synthetic thermal test platform, the akasa ak-860sf heatsink
yields a rise above ambient temperature of 39.4°c, with 45.2 dba noise from its
fan which rotates at a fixed speed of 2000rpm. the heatsink handles the
thermal load satisfactorily, but underscores its position as an
economical cooler for lower wattage processors.
by way of comparison to the socket 754 ajigo
mf043-044 heatsink, generally used as the stock heatsink for that class of
amd processor, the akasa ak-860sf runs about 4°c warmer. bottom line, the
Akasa AK-860SF is no frills
heatsink that will cool a lower wattage AMD K8 processor to within satisfactory temperature values.
