Fan is running A LOT more in Tiger

Well I think that is because many more features are running in the back demanding more CPU power...or load...therefore more heat

Is anyone else having a problem with the fans running constantly?

No problems here. You said you 'upgraded' to Tiger, does this mean you didn't do a clean install? I did an upgrade first and Tiger ran well, but not perfectly. There were some small idiosyncracies with some of the new features and some of the old programs. I then did a reformat and install and it's running better than ever.

I find that the people that do a clean install don't have as many problems as the people who just do an upgrade and save their old system files. Try doing a clean install, i'm sure it will fix your problem. Also check all the background programs that are running, some of them take up a huge amount of the cpu.

Also, before this thread explodes into another debate with a certain MR member about the merits of a clean install, have you tried resetting the PRAM and NVRAM? It doesn't seem to me so far that there is any consistent pattern of notebook computers affected by this issue, although I don't think I've heard of it with any iBook users.... I'm not sure about that. But anyway, I believe that the power management hardware controls the fan too, doesn't it? This might be an easy place to start, and it doesn't involve any real hassle beyond rebooting.

Did you ever have Virex installed on your TiBook? It doesn't play nicely with Tiger at all. I'd disabled mine but used the uninstaller script to wipe it out completely and it stopped the fan running quite so much in my AL book.

I do still find Tiger is running a little warmer though.

With Quartz 2D Extreme turned on, Tiger runs cooler on my 12" Albook.

That's not going to help on a TiBook.
