Temperature data was obtained by directly reading the Athlon64 thermal diode with a MAX6655 reader which offers an accuracy of 0.125°C. The CPU, cabling, diode reader setup has been calibrated in a water bath over a 0°C - 75°C range. Room temperature was kept at 20°C, data has been normalized if necessary.
Idle means Windows sitting at the desktop for 30 minutes. Load is after 30 minutes of Prime95. The different clock/voltage settings are representative of an un-overclocked, medium overclocked and heavily overclocked system.
As fan we used a Dynaeon DF1209BA high flow fan.
If you take the retail price of this heatsink into consideration this is a quite good result. It seems that most heatpipe coolers are very close to each other in performance. What I find interesting is that in the second test, which is medium overclocked, the Ultra 90 can improve compared to the other two tests.
