Is that OC with or without hyperthreading disabled?
I have to echo what others are saying - far too many volts and it's running far too hot because of it.
It wouldn't always hit those temps outside of stress testing, but it will still run far hooter than it should.
Also, 5 passes of IBT is grossly inadequate for any 'real' stability indicators.
I have a bad batched DO 920 which is a volt hungry pig and tbh, going any higher than 4ghz just isn't worth the volts, or heat for virtually zero noticeable difference in 'real world' performance.
