FrostyTech Mk.II Synthetic Thermal
Heatsink Test Results
AMD Phenom
II, Athlon II/64/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 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 amd version of the
frostytech synthetic thermal test platform, the low profile Zalman
CNPS8900 Extreme heatsink yields a good temperature result of 17.2°C over
ambient at stock fan speed (48.2 dBA noise). After slowing the integral 110mm
fan from 2800RPM to 1250RPM, noise levels fall to very nice 34.8 dBA. At this
reduced fan speed the heatsink is whisper quiet and maintains a temperature of
24.2°C above ambient.
Now this is key for anyone running a HTPC or miniITX AMD
computer system - as far as sub-75mm tall heatsinks go, the 60mm tall Zalman
CNPS8900 Extreme is the best performing thermal solution of this reference
list.
The next five runner ups are the Zalman CNPS8700 LED
(66mm tall, 2.3°C warmer), Cooljag SFO-Q (62mm tall, 5°C warmer), Noctua NH-L12
with bottom fan only (65mm tall, 7°C warmer), AVC Z7U3301 (59mm tall, 7.4°C
warmer) and Zalman CNPS7500-Cu (65mm tall, 7.8°C warmer).
The results
for this heatsink on the Intel version of FrostyTech's synthetic thermal test
platform are up next.
