Hey all, I currently have a 3570k and a Phantek ph-tc14pe cooler and on the default volts of 1.1v with a 4.2ghz overclock my temps reach around 58 degrees max, which seems good and fine, but when I try to approach around 1.15 or 1.6 with 4.5ghz the temps hit around 65/67degrees which seems a bit hot for this voltage? as i've seen people say they recommend using 1.2v and on that I get between 70/75 degrees on a Small FFT test with Prime 95, I know my cooler is more than up to the job but I was wondering do I just have an average chip, or is my cooler underperforming for whatever reason? thank you for the help
