For our temperature tests we loaded the system for 15 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 15 minutes before recording temperatures. Room temperature was maintained at 18 degrees Celsius for the duration of the tests.
We can see that the H80i performs much better than the original H80, especially in the overclocked tests. We can also see that it offers a similar level of performance to the H100i which is impressive considering the compact radiator.
