I really don't want to degrade the lifespan of my i5 4690k at a fast pace, currently I'm stable at 4.5ghz @ 1.260V with the hyper 212 evo. My maximum load would be streaming h1z1 on ultra and that brings me up to 55-60c, when stress testing its about 65-70c(prime95 and intel stress test utility). Do you guys think I could try and push 4.7ghz?
