12" Powerbook fan always on

Message #1 - Posted 2005/02/23 - Justin McKillican

I have a first generation 12" powerbook g4 and i'm getting the urge to smash it with a bat. Back when 10.3.4 was released, Apple updated the kernel extention that controlled the fan and caused it to start at a lower temperature. I was annoyed that the fan was always on so i used the kext from the 10.3 CD and replaced it.

All was good until 10.3.8 was released and Apple updated the kext again and now the fan is always on. Going back to the old kext really isn't the solution because the same thing will happen in 10.4 and the old kext wont even be compatible with the new kernel.

The most annoying part is that this powerbook doesn't even feel any cooler, it almost feels warmer. I'm wondering if this is a common problem for first gen 12" powerbook g4s or if there is a convenient fix (not for just the fan, but the heat issue).

This thing gets so hot, that simply typing this message caused my palms to get all sweaty from resting on the cover.

If it gets so hot, how high is the CPU-usage ?
If there is a high CPU-usage which process consumes it ?

barely any cpu usage. it seems to simply not be able to cool down once it generates any heat.

Hm, that the PB gets warm is normal. But it should not get hot. If it gets hot the fan has to start. Did you make a clean install of 10.3 ? Did you zap the PRAM and the NVRAM ?
So, zap both, make a clean install of OSX, don't install any additional software. If the problem persist, there may be something wrong with your logic-board.
