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 frostytech's synthetic AMD K8 thermal test platform, the
Asus Arctic Square heatsink maintains a rise above ambient temperature of 20.9°C at
full speed (2300RPM, 38.3 dBA). When we allow the Arctic Square's 92mm PWM fan
to decrease to 1200RPM, we see an increase in temperatures to 29.0°C over ambient. Noise
levels hover in the region to 39 dBA - arguably quite quiet.
Thus far the Asus Arctic Square is looking like a nice lower noise option, but we'll
hold off our final judgements til the socket 775 thermal test results are in. That's
next.
