so I overclocked my stock 2.8 GHZ intel i5 760 quad core to 3.05 ghz. i just changed the base clock and left the multiplier at 21. i didnt change any voltages. i turned off a bunch of settings like C STATES and Speedstep. is this why the temperature is so high now? The temp now is 37 Celcius idle and before the overclock at 2.8 ghz it was only around 25-30 C idle. i got a zalman 9900 cpu heatsink too. do voltages affect temperature? i have an evga p55 le mobo btw. if that matteres.
