Ever since I started folding@home on my iBook, I leave my computer running all day while I am at school. Now that the weather is getting hotter (around 80 degrees and humid) I have noticed the fan running constantly. when I return home and go on it, the computer is very laggy and slow in general. I know that the computer has a fan, but could I be damaging the computer in any way by letting the fan run constantly in the heat? Thanks. BTW, I wasn't sure which forums this would be most appropriate for, but Im sure someone running folding@home has encountered this problem before.
