Not a problem with Tiger. If the fans on his iBook are running at full speed all the time it could be hardware related. Possibly a defective thermal sensor or it may even be that his iBook is running hot. If the iBook is running hot, the fans will speed up accordingly.

Regards.

thanks for the reply chscag

I do not believe it is running to hot because the fan is blowing out cold air also the temp meter says it is at 20 degrees.

The weird thing is that yesterday the fans stopped and it worked great for a couple hours now its restarted the fans are going at 100% again.

He does not mind , but last week he had to leave hasty the library because people were complaing about the noise of his computer.

There doesn't happen to be a program to manually change fan speed ?

thanks
