I recently applied the Arctic Cooling 13 pro to my 3570k after the excessive temperatures I was getting with the stock cooler at 4.2ghz (50 degree idle!). I am now looking at 35 degree idle, 70 under full load and holds late 50's when gaming. I was quite happy with these results at first, but looking around the internet people seem to be achieving lower temps than this at higher clocks. Could the fact that I have left the voltage at auto have anything to do with this? (Although voltage seems to peak at around 1.18v) Thanks.
