How much of a temperature increase should I expect when overclocking?

[Silverhand7]

I have an i5 2500k, currently running at stock speeds. I currently have a Hyper 212 Evo for CPU cooling, and get around 20c idle temps, 30-40c while gaming. If I overclocked my 2500k to 4.0 GHz how much of a temperature increase should I expect? What about 4.5 GHz? Just curious if I'd need to worry about temps if I overclocked, or if I'd be fine doing so with my current cooling.

It all depends on how much you increase the voltage to your CPU. move volts=more heat. Don't push it too far though, 1.5 volts is pushing it. Since the 2500k is a SB arch chip it will fare better then IB, so if you can find a good IB guide then you should be able to do what that guide does and a tad bit more.

What voltage should I run it at for running around 4 GHz?

You can do 4 Ghz at stock voltage. If not 1.125v

Okay, thanks.

With the 212 Evo, you can get 4.2 (with increased voltage), maybe 4.4 GHz depending on whether you got a good chip. 4GHz is a very safe OC and you will not be required to raise the voltage. You might see a slight temperature increase, but as long as it's below 70C you'll be fine, really.

If you have a decent chip, you can get to 4.5ghz at about 1.3v, temps should be at about 60-65c under Prime95.
