Mk.II Synthetic Thermal Heatsink Test Results
Results based on readings from a 38x38mm
copper interface die with 125W heat load on the Mk.II Test Platform.
Thermal Test values for each heatsink were calculated by determining
the rise over ambient temperature at time of test. Information on
Frostytech's test methodology is available
here. |

125w thermal test (°c) |
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 Fatal1ty
FS-C77 heatsink yields a very good 26.7°C rise above ambient temperature result,
with a moderately loud 56.5
dBA of noise produced.
As a
performance-oriented
heatsink the Zalman FS-C77 does well for itself, but there are several
other heatsinks which dish out much better temperatures
within the same noise-class.
How about the Fatal1ty version compared to the
base Zalman 7700-series heatsink?
Well, compared to the identical Zalman CNPS7700-Cu
heatsink which nets a rise above ambient temperature of 27.0°C (with 50.7 dBA
noise), the verdict is a pretty clear one... A coating of red paint, and a
slightly quicker fan (2400RPM vs. 2000RPM) does not for a super leap in
performance make.
The Fatal1ty FS-C77 heatsink is a bit better than the regular
Zalman CNPS7700-Cu cooler, but not significantly so, and particularly given the higher
prices a "Fatal1ty" branded
heatsink seems to demand.
A quick
check of the major online vendors shows us that the Zalman Fatal1ty FS-C77
heatsink retails for an average of $63 USD ($71CDN, £33GBP), where as the
Zalman CNPS7700-Cu retails for about $50USD
($56CDN, £26GBP) on average.
By removing
the Fanmate 2 from the equation, the stock Zalman CNPS7700-Cu heatsink just about
matches the thermal performance of the Zalman Fatal1ty FS-C77 heatsink,
and you save $13.
