I recently sent a 1ghz titanium in to apple to get a new logic board and optical drive. Just before I sent it in I upgraded the HD to 80GB 5400 rpm hitachi. I cloned the old drive onto the new one when I got it back, so the OS and contents are identical.

Since it's been returned to me the fans are always on. When starting from cold, the fan will go on within 10 minutes even if the processor is @ 5% and/or I'm doing nothing but typing in emacs in the terminal even if I have it set to reduced speed. It also seems hotter than I rememeber, although this is largely toward the back of the computer.

Anyone have any input as to what to do? I've reset open firmware, nvram, pram, pmu. Could it be that this is simply a hardware problem that I have to send it back to them to fix? Or is it just due to the new HD?

It's probably the new logic board. Maybe you're getting better performance and not noticing it.

try plopping your old hd back in, just for testing purposes, the new hd is more then likely gonna run a bit hotter.

On my 500Mhz Ti I can _always_ get the fan to turn off by elevating the back of the PowerBook and popping open the Keyboard. This dramatically increases the air flow to the internal components.

Yes, I know you can't type on the keyboard when it is propped open BUT... if this doesn't shut down the fan you've got bigger problems

The heatsink assembly may not be making proper contact with the cpu. This can happen if the tech torqued the screws too much and ended up loosening the heatsink standoffs attached to the motherboard. Take it back and get them to look at it.

That sounds about right.

I know it's not the HD. The heat is at the rear of the machine and it is quite hot. I've been using this thing for two years and had a 500 mhz titanium for over a year before that, so I can tell this is not normal.

I guess I'll have to call apple and hopefully they'll fix it.
