Quick question. When my cpu is clocked at 3ghz its idles at 36-38c but when clocked at 3.4 it drops to 28-30c.

Im not sure why? Anybody know

Just what method you are using to monitor temps? (softwares like coretemp or TAT?) or hardware like the mobo temp sensor or a probe?

Heat cancellation. At stock speeds a processor produces XX amount of heat. When you overclock, the extra heat generated cancels out the stock heat, resulting in lower temperatures.

That's why you need a bigger heatsink on an overclocked processor. If you overclock too much, the processor will eventually cool down to below the dew point in the room. The larger heatsink spreads out that cooler temperature over a larger area, meaning it won't get as cool, and keeping condensation from forming on the chip and shorting it out.

Common sense actually.

Im using everest to monitor temps, And my cpu stock speed is 2.4 so is overclocked either way?

I hope that's a rubbish attempt at sarcasm via an American.

It wasn't meant to be sarcasm. It was meant to be a humorous response. That was in no way a sarcastic comment. Maybe you should look up the definition of that word before you make rubbish accusations
