I have a 4670k with a Corsair H100i. I just recently noticed that my CPU was up to 90 C when playing Battlefield 4 and about 46 C when idle. I used to get a high of 65 C when gaming and 31 idle. I've had the PC for 5 years now, so I figured it might be the thermal paste. I replaced it and there is no change in temperature. I turned off Intel Turbo Boost in BIOS and now CPU is running at stock 3.4GHz. Still no change. The PC is free of dust and all fans look to be running normally. I cannot see anything unusual going on in task manager either (MSI Live Update used to give me some issues). I would appreciate any help you can give me.
