I think its time to actually look inside the computer and count the cpu's.

Come on man, give me a little credit. There are two.

I've taken it into my local service center and should have a diagnosis early next week. Thanks for your help everyone, I do appreciate it. ;-)

I can't think of any reason to count the processors. Apple never sold a machine with only one 2.0 GHz processor.

I was going to suggest the same but I'm not really a mac person so much so my experience is limited... on the macs, G5's actually, is there two seperate heatsinks or one large one that sits on both?

Also at work we have a couple G5 2.5's and yes, any flash page or flash banner seems to cause the fans ramp up in speed. Its a little on the annoying side because I'm not sure there is enough time to cause the processor to heat up that much (we're talking 3 seconds after entering a page with flash) so my guess is its doing it based on CPU load and not temperature.

DeltaMac will become famous soon enough
To the question about separate heat sinks, the dual processors have separate heat sinks, except for the water-cooled models (2.5 and 2.7 duals), which can't be separated from the cooling system - the radiator and a micropump is shared by both processors.

The fans on my G5 will occasionally ramp up for a few moments (as they coincidentally just started doing). It sits under my desk, and the fans are not unpleasant. As I finish typing this, they have slowed back down.

As to what controls the fan, there are several temperature sensors throughout the case.
