Temperature data was obtained by directly reading the Athlon64 internal thermal diode. It offers an accuracy of about 1-2°C.
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. The high voltage settings were used to get a sufficient heat output on the CPU, not to reach the overclock.
The Cooljag Falcon 92 Cu is certainly not the coolest heatsink of our test group, but it can keep up with the pack very well, especially when the heatload is smaller. Once we start serious overclocking we can clearly see the Falcon92 fall behind. However, our test system was stable at all times.
Fan Noise
To measure fan noise we used an IEC Type 2 sound level meter on the dbA setting. Measuring distance was 10 cm from the heatsink fan hub. The short distance of 10 cm is necessary to get proper readings with very silent fans. All fans were tested outside of the case at 12V supplied by a lab PSU. On fans that come with a fan controller or allow control of fan speed in any other way, "low" and "high" indicate the settings on the fan controller.
In this field the Falcon 92 Cu can excel. It is by far the quietest heatsink we tested so far, with the exception of the Scythe Katana Cu which was running via fan controller on low speed. If you take the temperatures this cooler delivered into consideration when looking at how quiet this cooler is, you will realize it is an extremely efficient design that can run quiet, yet deliver stable performance.
