I happen to love old Tibooks. Really old ones. Non DVI ones, to be exact, cuz my eyes like the bigger type on the lower resolution screens. So 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?
