I noticed yesterday that my Athlon XP 1800 was running at 1.1ghz (set in the BIOS) instead of 1.5 like it's supposed to, so I switched the setting (god, how long was THAT set?). When I got into windows, I loaded up the Asus Probe (mobo monitor) and it was warning me that the 12+V threshold was up around 13.2 (no idea how bad that is) and my CPU temp was hitting 70 C (more on that later).

I have the following: 4 case fans and a case that all glow a fancy neon color, 2 HD (60 gig / 40 gig), a firewire card, wireless nic, DVD burner, CD writer, and a radeon 9600 pro - all powered by a 350 watt PSU. Is that my problem? If so, should I aim for a 400 or 450?

Another thing that was odd... it seemed like stuff was crapping out on me after I had turned the CPU speed up. The XP startup screen was scrambled much like the old NES games that would screw up occasionally. My first thought was "oh shit, I burned something ... " but after shutting the system down and then restoring the old (slower) speed, everything seemed fine. Would that be something caused by insufficient power or is that overheating?

Regarding CPU temp: How is a chip that's SUPPOSED to run at that speed (1.5ghz) be running so HOT? At 1.1 ghz it hovers around 60 C. I have 4 case fans.. one in the front (sucking air in), one in the back (blowing air out), one on top (in), and one on the side directly above the cpu (in).. I think that's some pretty decent cooling, so what gives? I also thought this was kinda odd because I had JUST cleaned a ton of dust off my heatsink & fan.
