great, Thanks!
Looks like my 560ti isn't getting enough power when it needs it (crappy Xtreme Gear psu). So I'm going to order the XFX PRO750W Core Edition first ($65 w/ rebates right now on amazon) to see if I can get the 560ti running properly. Even if that doesn't fix my GPU fan issue, I'm due for a psu upgrade anyways. (Not that it's needed for the 750ti)
