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 here. |

    | *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 k8 
version of the frostytech synthetic thermal test platform, the Noctua NH-U12P 
heatsink yields a very nice rise above ambient temperature at stock fan speed of just 17.3°C, with 40.7 
dBA noise! That puts it within the Top 10 AMD heatsinks Frostytech has tested thus far! With the 
black fan speed reducer attached the Noctua NH-U12P maintains a temperature of 19.5°C over ambient with only 
34.6dBA noise. With the blue speed reducer temperatures rise to 22.5°C and noise levels 
bottom out at 32.1 dBA. So far it's a very strong showing 
for Noctua's NH-U12P heatsink! 
The 
results for this heatsink on the Intel LGA775 version of FrostyTech's synthetic 
thermal test platform are up next.
