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. |

Frostytech tests
with two thermal values that represent the upper limits of existing Intel CPU
families. With a 150W heat load applied by the Intel LGA775 version of
FrostyTech's synthetic thermal test platform first, the Zalman CNPS9900 LED
heatsink maintains a very good temperature of 20.2°C over ambient (57.5dBA
noise) at full fan speed.
Under similar test conditions and reduced fan speed, the
noise output of the Zalman CNPS9900 LED levels off at a quiet 39.3 dBA, while
temperatures rise moderately to 30.6°C.
Zalman's
CNPS9900 LED heatsink was then tested with an 85W heat load; akin to a Core
2 Duo processor. In this test the CNPS9900 LED was more at home and easily
maintained a result of just 13.3°C over ambient temperature at default fan
speed, and 18.1°C at its reduced fan speed.
As you've
seen in both Intel and AMD thermal test results, the Zalman CNPS9900 LED
heatsink is a good lower noise thermal solution when its fan is running at
1000RPM (*see Tip below). There are of course other LGA775 and AMD K8 heatsinks
which manage similarly low noise levels with better performance, but LGA1366
compatibility is another matter entirely... With its fan running at full speed
the Zalman CNPS9900 LED offers up very good performance, but sacrifices silent
running.
*TIP - Here's the real tip for users of the Zalman
CNPS9900 LED heatsink... Remove the plastic fan shroud. When the fan is running
at 2000RPM this will reduce the sound pitch noticeably and drop noise levels
very slightly (~2 dBA), in addition to lowering temperatures by about a half a
degree. The real benefit however comes when fan speed is at its lowest. In our
tests noise wasn't significantly affected by removing the fan shroud while the
fan was spinning at 1000RPM, but the CPU die temperature did drop by a good
5-6°C!
