FrostyTech Mk.II Synthetic Thermal
Heatsink Test Results
AMD Athlon64 / FX / X2 &
Sempron class heatsinks
Results based on readings from a 38x38mm copper
interface die with 125W heat load on the K8 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

noise level (dba) |
| *heatsinks are
ranked according to the 125w 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. |
With a 125W heat load applied by the FrostyTech synthetic
thermal test platform, the Zalman CNPS7700-Cu
heatsink yields a good 34.0°C rise above ambient temperature at its lowest and
quietest fan speed, with only a whisper of 35.1 dBA noise. When we
turn the dial of the Fan Mate2 all the way up, the CNPS7700-Cu's
120mm fan spins away at an even 2000RPM. This is known as the "low-noise" or
"normal" fan speed mode, and in this setting the CNPU7700-Cu yields
a rise above ambient temperature of 27.0°C, with 50.7 dBA noise. A very
good thermal result by any standard, but not as low as units by Noctua, Thermalright, Apack, or Arctic Cooling yield for
a similar noise class.

As a low noise heatsink for the socket 939 AMD
Athlon64 platform the Zalman CNPS7700-Cu heatsink is very good at what it does. Only
the Zalman CNPS9500 LED, Verax Helado, and a heatsink Frostytech will be
reviewing shortly from a company called Thermalfly post better thermal
results with similarly low noise outputs (36.0 dBA, 36.2 dBA and 35.4 dBA
respectively).
On the socket 775 Intel platform, the Zalman CNPS7700-Cu is equally well positioned
as a low noise heatsink, although the design is clearly starting to give way to
heatpipe-based models.
However, as low noise heatsinks go,
the Zalman CNPS7700-Cu is getting a little long in the tooth. Newer
models like the Zalman CNPS9500-AM2 have surpassed its capabilities, but for the
right price the CNPS7700-Cu still offers a lot.... and quietly too.
