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 amd k8 synthetic
thermal test platform,
the
Xigmatek HDT-S963 heatsink yields a rise above ambient temperature of just 20.1°C, with 50.2 dBA
noise generated as the fan spins at full speed. Operating with a
decreased fan speed of 1200RPM next, the Xigmatek HDT-S963 is able to maintain
a very impressive temperature of 24.9°C over ambient, while noise output falls 32.8 dBA!
For such a dramatic drop in noise, the Xigmatek
HDT-S963 heatsink runs just 4.8°C warmer!
Excellent results so far, but as usual we'll hold off on our
final judgement of the Xigmatek HDT-S963 heatsink until the Intel LGA775 test results are
in. That's next....
