I wanna download torrents at night and turn down my fan speeds so my pc is quite then my temps will go way up. So is there a way without turning off my pc to downclock down my cpu so my temps lower?
Yes, turn on the Intel speedstep feature. You can do this by first making sure speedstep is turned on in bios and then selecting "minimal power managment" in the power profile.
start>control panel>appearance and themes>choose a screen saver>power.
