hotkey overclock?

[renandstimpy]

I have a i5 2500k in a Asus maximus IV gene z. is there an app or something to overclock by a hotkey? so if I create an overclock profile in bios, then a hotkey in Windows activates it.
I ask because I'd like my pc to run quiet and possibly underclocked when in basic use, then run it overclocked in games. Thanks for any help.
