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.

*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. |
The heat output from
Intel processors varies between single and multi-core solutions so FrostyTech
must rely on two thermal values to represent the upper limits of each class of
CPU; 150W and 85W.
With a 150W heat load first applied by the
Intel LGA775 version of FrostyTech's synthetic
thermal test platform, the
Scythe Mine Rev.B SCMN-1100 heatsink maintains a temperature of just 23.6°C over
ambient (36.8dBA noise). The easily places the Scythe Mine Rev.B within the top
10 of LGA775 heatsinks tested in this reference list.
The Scythe Mine Rev.B heatsink was next tested with an 85W heat load. In this case the
heatsink managed a result of 15.0°C over ambient. Fan speed was held steady at 1500RPM, so
the Mine Rev.B heatsink continued to run with a whisper quiet noise level
of just 36.8 dBA
From the test data we have seen here, the Scythe Mine Rev.B SCMN-1100 heatsink is an
excellent thermal solution for either AMD Athlon 64 or Intel Core/Quad Duo/Pentium D platforms.
The Mine Rev.B managed to perform within the top 20% in both circumstances,
and with less than 40 dBA noise generated! It did not outperform the stock
AMD AM2 heatsink thermally, but did provide lower temperatures than the stock
Intel Penium D bifurcated fin cooler which is in wide use today. Scythe have
created an excellent low noise, high performance multi-platform compatible
heatsink here. As such, FrostyTech recommends you consider the Scythe Mine Rev.B
SCMN-1100 heatsink if you case can accommodate its size, and if you're looking
for lower noise levels and lower CPU running temperatures.
