well i had an OC of 4.6 that had alright temps however, ever since i had to remove my motherboard and replace the the stock thermal paste that came with the H100I to Arctic silver 5. they have seemed off every time, i've reapplied it multiple times. with different methods rice, pea, line, and i still can't find a sweet spot. I've had to revert back to stock clocks as my cpu was getting up to 61 62 degrees and the package 60+ this is what i'm getting at stock. running prime for 20 mins. ambient temp is 74.3 F
