I'm running a gtx690 with an i72600k factory overclocked at 4.1 GHz from Alienware. I do see a lot of other owners of this CPU running it at over 4.5 ghz . I currently see temps of about 58c-60c under load. Would I benefit from a bit more over clocking and what max temperatures are safe? The chip is factory liquid cooled. Thanks in advance for any suggestions.
