To explain my setup firstly. I have just build a pc. Corsair 650D case, with an Gigabyte board, Evga 660Ti, 8gb of ram, one ssd and one 1t Hd. The cpu is a i3770k being cooled by an Corsair H110. I have tried to do a pull and push but due to the lack of space i have two fans on top of the rad pulling while only one on the bottom as push due to lack of space mounted to the top of the case. The back 120mm fan is pointed inwards to blow fresh air from outside directly on the radiator as well. Now to the question. I have after a week of letting the pc burn in at idle speeds, i have used the build in gigabyte program EasyTune to oc the cpu to a 4.1Ghz and while with RealTemp up I run the IntelBurnTest a couple of times. Well firstly idle it sits at about 30C. But while the burn test was running one of the cores reached 81C. That seems awfully hot to me. Anyone got any opinions or different tests I can run to make sure I am not running the system too hot.
