thermal paste problems on old Tibooks?

Hi,


I have owned, like six Tibooks over the years. And this latest used example of Apple, year 2002, is a 550mhz Tibook with a gig of ram.



And the fans turn on ALL of the time.



The fans RARELY turned on on the 400, 500, 667 and 1 ghzs I had before.



Could this be an early example of slapped on thermal paste? Anyone know where the paste would be on these old PBs?



Please help.

Thanks!



I didn't find the right solution from the Internet.
