For our 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.
The Corsair H110 showed excellent performance in these tests, beating the H90 by around 3 degrees in the stock test and 5 degrees in the overclocked test. The H90 also performed well, achieving better scores than both the high-end air heatsinks tested.Corsair Hydro H90 and H110 (with i7-3930K) Review,
