Why does my C2D Macbook Pro fan run constantly?

I have a 2.33 Core 2 Duo Macbook Pro 15 inch laptop. Recently, I have noticed that both fans on it constantly run at the maximum 6000 rpm's. The noise is driving me nuts, and the battery seems to run out much sooner. My question is in two parts: (1) would anything in the system logs help explain why this is happening? and (2) how can I make it stop?

Here are the steps that I have taken to try to diagnose the root cause:
(1) reset PMMU per these instuctions
(2) setup new blank user account to see if it was software related (it wasn't- the fans actually kick in at full blast even on the login screen)
Please help me understand what is causing this. The bootup temp is 106 degrees F, so I really do not think it is temperature related.
