Thats a bit too high for an overclock of 4ghz.
I run it at 4.6GHz at 1.32Vcore and only get 60C max under prime blend test using the same cooler.
Try lowering it to 1.27-1.25, or as low as you can.
Also, how many fans do you have on it? And what fans are you using?
I currently have the voltage on Auto as i didnt want to put it to high. Ill try doing it manually.
i have one fan on it and its the fan i got with the cooler.
What happens if the voltage is to low for how much ive multiplied it by?
