I bought recently i7 4770k with mobo asus maximus vi hero cpu running @ 4.2 (I know it's not much) I am getting about 90c on FPU test @ 1.2 v AIDA64 and if I run higher voltage I will hit 100c I know it's high temp. but I tryed everything nothing to do with it! I am using Asus AI III for OC because I am begginer in OC, but in the same time my system is stable I am able to play BF4 on ulta @ 1920X1080 100+ fps and compress HD video in the same time and geting just 55~65 c temp. and system run normally , so what do you think guys I should worry about my CPU and try to return it or just forget about those stress test and just keep using my pc in real world apps?? please advice me.
