FrostyTech Mk.II Synthetic Thermal
Heatsink Test Results
Intel
Pentium D / Extreme Edition & Quad Core class heatsinks tested
at 150W
Intel Core 2 Duo / Pentium 4 /
Celeron class heatsinks tested at 85W
Results based on readings from a 30x30mm copper
interface die with 150W and 85W heat loads applied on the LGA775
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. |

| *heatsinks are ranked according to the 150w 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. |
Intel socket 775 processors vary in power output between
single and multi-core models, so FrostyTech tests heatsinks with two thermal
loads that represent the upper limit of each CPU family; 150W and 85W.
With a
150W heat load applied by the Intel LGA775
version of FrostyTech's synthetic thermal test platform, the EKL Alphenfohn GroB
Clock'ner Blue Edition heatsink yielded a very good temperature of 21.0°C
over ambient, with 42.4 dBA noise. With its fan slowed down to 800RPM the
heatsink outputs just 30.7 dBA noise, while temperatures hold steady at 28.7°C
over ambient. A good, but pretty average result.
The GroB
Clock'ner Blue Edition heatsink was then tested with an 85W heat load, and under
these conditions maintained a 12.9°C rise over ambient at stock fan speed, and
16.9°C at the lower RPM setting.
As you can see by the results, the EKL
Alphenfohn GroB Clock'ner Blue Edition heatsink essentially performs the same as
the straight Alphenfohn GroB Clock'ner model. The use of the Coollaboratory Liquid MetalPad would have undoubtedly changed
the results, as it would for any other heatsink.
In any
respect, the Alphenfohn GroB Clock'ner Blue Edition is a good
relatively quiet heatsink for both Intel and AMD platforms. While there are
a handful of heatsinks which run cooler, the majority of those are louder
than 42 dBA which makes this CPU cooler worth considering.
