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.

Noise Level (dBA) |
| *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 widely between single
and multi-core processors, so Frostytech tests heatsinks with two thermal values
which represent the upper limits of each breed. To start with, a 150W
heat load was applied by the Intel LGA775 version of FrostyTech's synthetic
thermal test platform. The
3RSystem Iceage 120 heatsink yielded a rise above ambient temperature of
only 18.2°C (47.9dBA) at a stock fan speed of 2200RPM.
The CPU equivalent of this test would be an Intel Core
2 Quad, Pentium D/Extreme Edition class processor. With such a low rise in temperature, the
Iceage 120 heatsink takes the number two position in this Intel reference list. Impressive!
The speed of the 120mm fan on the 3RSystem Iceage
120 heatsink was then reduced to about 1000RPM. With a reduced fan speed noise levels
decreased to 35.4 dBA, and the test temperature rose to 24.0°C over
ambient.
When faced with a 150W heat load and a slowly spinning fan, 3RSystem's Iceage 120
heatsink maintained significantly better results than the stock Intel LGA775
heatsink... and in fact the majority of Intel heatsinks Frostytech compared it
against.
For the next round of tests on the Frostytech Mrk.II synthetic thermal test platform, an 85W heat load was selected. The Iceage 120 heatsink maintained an excellent 12.1°C rise
over ambient at default fan speed, and 15.0°C at a
reduced fan speed. Once again, the 3RSystem Iceage 120 heatsink posts very good thermal
results.
Compared to the stock AMD Athlon64 AVC Z7U7414001 (AM2) heatsink at full tilt the 3RSystem
Iceage 120 heatsink is much quieter, and a bit cooler. On the Intel platform,
the Iceage 120 is dramatically cooler and about as loud as the stock Intel Pentium D/Core 2 Duo
bifurcated-fin heatsinks.
As we've seen from the thermal and acoustic test results for both AMD and Intel
platforms, the 3RSystem Iceage 120 is an excellent lower-noise heatsink at
the top of its game. However, 3RSystem would do well to revise
the clip mechanism and make it a bit easier to center it on the base of the
heatsink. In an open top test environment it was tricky to keep the
mounting clip centered on both those steel pins, so we can foresee some
frustration coming from them in the confines of a computer case. Otherwise,
the quiet low-RPM hydraulic bearing fan, anti-vibration pads, and
performance of the Iceage 120 heatsink come together
very nicely. Recommended for Intel or AMD processors.
The 3RSystem Iceage 120 heatsink is available through JustPCUSA.com in US/Canada,
international vendors are listed here.
