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 Coolink Silentator
heatsink is able to maintain a temperature of only 15.2°C above ambient!
This is the second best test result for an AMD K8 heatsink thus far, outdone
only the Thermalright Ultra 120 CPU cooler. The Ultra 120 generated 53.7 dBA
noise to achieve its result, compared to the Coolink Silentator which produced
only 41.2 dBA at full fan speed (1600RPM).
The
Silentator heatsink was next tested on the K8 synthetic temperature platform at
a reduced fan speed of about 900RPM. At this pace the 120mm fan generated a
whisper quiet 32.5 dBA, while maintaining a 19.4°C over ambient temperature.
In spite
of a 8.7 dBA decrease in noise levels brought about by a change of fan
speed from 1600RPM to 900RPM, the synthetic CPU die temperature rose only 4.2°C.
Excellent results so far, but we'll hold off on the final judgement until the
Intel LGA775 test results are in next....
