The fan in a TiBook is bonded to the upper housing, back center. There
isn't room to put anything close to the processor, since it is covered
by the heat sink/extraction tube assembly. Plus the 'Book is so thin
there isn't room for anything else anyway.
Not even a thin detector of 2 mm?
Perhaps the heat sink isn't
dissipatingn enough heat? I have a 500mhz and the fan rarely comes on,
usually when I am running Virtual PC for over an hour at a time. You
might try putting some thermal compound on the top of the processor,
under the heat sink contact.
I'll certainly try that. It's the previous user that says the fan never
comes on, I haven't judged this myself. You know anything of what
hardware judges and control the fan?
There is a little bit of room on top of the heat sink, but not very 
much. Are you talking about a fan that is 2mm thick? That wouldn't move 
very much air. Lift out the keyboard, you can see the heat sink 
assembly.
As far as controlling the fan, I don't know. The early G4 processor in 
the 400/500 TiBook also doesn't send the signal to software that's 
available for monitoring the temperature. Perhaps some of the more 
technical people on the list can digress about the different G4's that 
Apple has used.
