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, so Frostytech tests with two thermal
values that represent the upper limits of existing CPU families. With a 150W
heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal
test platform first, the Coolage Frozen Orb Z924 HDC heatsink maintains an
average result of 29.2°C over ambient (56.0dBA noise) at full fan speed.
This result is about 3°C cooler than the Freezer Orb
FO-Z924AL model on which its design is based.
With the
speed of its 95mm PWM fan reduced from 2500RPM to 1000RPM noise
levels decrease to 31.9 dBA. In this scenario the Coolage Frozen Orb
Z924 HDC just manages to hold steady at a satisfactory 52.2°C over
ambient.
Coolage's
Frozen Orb Z924 HDC heatsink was then tested on the Frostytech Mrk.II synthetic
thermal test platform with an 85W heat load; akin to a Core 2 Duo processor. In this scenario
the Frozen Orb Z924 HDC maintained an average 18.7°C rise over ambient
temperature at default fan speed, and 32.2°C at its reduced fan speed.
Based on
these results it's fair to say that while the exposed heatpipes do help the
Frozen Orb Z924 HDC model post a slight improvement in performance at full fan
speed over the previous Freezer Orb F0-Z924AL version (which had a solid
copper base), the heatsink is still limited by its compact size. An
increase in the surface area of aluminum fins could have changed the
equation, but instead Coolage simply modified an existing heatsink design by
removing the base and exposing the heatpipes.
Ultimately the Coolage Frozen Orb Z924 HDC provides no more than average
performance at full fan speed, and satisfactory results when operating in quiet
mode. The heatsink is suitable for energy efficient 85W processors, but for
higher TDP wattage chips the fan should be run at full tilt. Clearly though, if
height is not an issue there are very many other heatsinks to choose from which
offer both cooler and quieter performance.
