See under profile for system specs.
H80i + 4670k idles at just under 40, constantly. In prime 95, I'm hitting 75 degrees stock clock and voltage. Overclocked to 4.4, with a voltage of 1.2, it hits 95 then throttles and eventually shuts down.
It's set up as exhaust on my H440, and when it was intake at the top, it was hitting 81 stock. This seems way OTT, as my GPU is around 60 when gaming, and during some torture testing it hits 65, maybe 70.
Same thermal paste used (Arctic MX2).
