I have a g5 and its been at 108 degrees internally in this 73 degree room, for the past 2 hours and i'm worried about the processors being so hot?

I hit 148º today, no thermal shutdown. I think you're safe. :D
 
Wow. Under full load I've never seen them peak over 130ºF.

It corresponds to processor speeds. My dual 1.8 is like yours, it tops out around 130. My friend's Dual 2.3 tops out around 160-165. My dual 2.7 tops out around 195.
 
oh ok, my ibook reports a 150 F, that is normal, right?

Laptops are a completely different kettle of fish altogether & due to obvious thermal constraints will always feed back higher temperatures than what you'd find in a desktop system . I've seen my old PowerBooks hit 190 (under serious load, of course) before, which is really getting into the danger zone. My white MacBook has even hit 210+ before. For a laptop, 150 seems like a pretty average sort of reading to me.

Although all of the fahrenheit stuff is making my brain work overtime. Here in the UK we do our thing in celsius.
 
I can only report on my PowerBooks and my G5. Both PowerBook G4s will have their fans kick in at 140º. I've pushed them both in to the high 140s, but never 150+. My operating range tends to be between 118-140º.
My G5 with the old logicboard never went over 139º. This new logicboard seems to run hotter. Right now I'm at 142º.
 
My Quad idles with CPU A around 105°F and CPU B around 95°F in a 72°F room. At full load CPU A will spike to around 180°F and CPU B around 150°F until the fans and LCS ramp all the way up, then that settles down to about 170°F and 145°F respectively.
 
After monitoring the temps at full load, my quad idles at 74 f and under full load I have never even seen it go above 108 f


The reason being that I have a single room ac unit, and I ran a hose and attached it to the front grill of the g5 and I've got it blowing 43 degree air thru the system 24/7

:D

After seeing those temps I was going to question if you were running it inside a refrigerator.
