Bad processor?

Hi there folks, new to this forum but I'm hoping someone can help me out.
I recently built myself a new computer with a 3570k and went ahead and overclocked to 4.5GHz @ 1.225v and ran a few sweeps of prime. I noticed the temps immediately shot up to mid/high 80s. I am using a corsair h100i which I understood was a good cooler, so did I get a particularly bad or hot processor?

Thanks in advance if anyone bothers to reply
