Cool_Hand,
Are you running a Dual CPU mobo or is what you are calling the second CPU the Mobo's Northbridge? (The Northbridge will have a much smaller heatsink than the CPU and could either be with or without a small fan on it.)
It does sound like the room you have your computer in gets a little warm. Personally I do not like seeing the Mobo temps above 35C. It could be that the temps inside your case are getting a little high. As for your fans, they are all blowing in the correct direction from your description.
I would try keeping the side of the case open and pointing that desk fan (room fan would be better) at the area between the CPU and Vid Card.
If your Vid Card Driver reads:
ATI 9500/9700 128Mb
Then it sounds like you have a generic Driver installed. I would install the latest Catalyst Driver from:
Catalyst Driver Downloads
I would also look for the latest Drivers for all your hardware.
Take Care,
Richard
