For temperature tests we loaded the system for 10 minutes using Prime 95 and recorded the CPU temperature using CPUID HWMonitor. We then restarted the system and left it idling at the desktop for 10 minutes before recording temperatures. The temperatures recorded are based on an ambient temperature of 20 degrees C.
These temperatures are very impressive, showcasing the capability of this cooler. It is quite clear that it struggles a little with low airflow when overclocked as the temperatures were significantly affected in the low fan speed test.
