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 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 heatsink maintains a very good temperature of 20.8°C over ambient,
with 40.6dBA noise.
The Alphenfohn GroB Clock'ner
heatsink was then tested with an 85W heat load, and managed to maintain a 13.2°C rise
over ambient at stock fan speed under those test conditions.
So there
you have it, the EKL
Alphenfohn GroB Clock'ner heatsink quietly cools very well on both Intel and AMD
platforms. While there are a handful of heatsinks which run cooler, the majority
of those are louder than the 40 dBA the EKL Alphenfohn GroB Clock'ner puts
out.... thus the Alphenfohn GroB Clock'ner is well worth your
consideration.
