Anyway to adjust settings on processor?

Just FYI the rectangular box is converting the 110V A/C to something smaller and most likely DC. Same as the over-sized plugs powering your printer or external devices convert the 110AC to anywhere from 5 to 12V DC.

Yes, the power input on my desktop is marked "DC", just as a printer or notebook is. That's why I was wondering if I had enough power for a quad to begin with. Most desktops that I've seen doesn't have power supplied like a notebook or printer would (a DC connection).

Did you change the voltage or increase the Bus speed in your BIOS to speed up your processor? Because that would explain your higher heat levels.
