Booted up my TiBook 1.0 today after a longer pause of not beeing used and I noticed, that the fans don't ever stop to work. And even worse: "G4FanControl" and "HardwareMonitor" don't display any temperature-sensors at all. Then I found a note on the website of the developer of "HardwareMonitor", that Apple started to make temperature-sensors accessible by software for the first time in 2002, whilest devices before that time had an inbuild hardware-controlled temperature-management. Since the TiBook is from late 2002 I wonder if it just doesn't have those sensors too, or if something is broken!? When I got the device it was in a bad shape and definitively needed spring-clean. A lot of ashes-like dust sticked to the case close the fans ... looked like a fire from collected dust put out with Cappuccino. I still have to mention: same thing wether with os9, Tiger or Leopard. All systems installed from the scratch on separate partition on an mSATA/converter-combo and fully updated.
