Re:G4 heat issues? 12" model only 800MHz (Score 1)

Does the 12" Powerbook have a fan? Evidently my 900MHz G3 iBook does not (although this is subject to much conjecture among those of us unwilling to violate waranty by opening it up to find out). If there is indeed no fan in the latest G3 iBooks, then maybe there isn't one in the G4 iBook, either. This could explain the 800MHz cap on the processor. My G3 sure gets toasty at times.
