My pbook used to tun at about 53 degrees Celsius running normal apps, (safari, itunes, AIM). But ever since i got a new set of logitech speakers it has started to run around 58-60 degrees! Is it possible for the pbook to run up to 5 degrees more just by plugging in speakers. Before I added the logitech's I was using the built in speaks in the pbook. Any tips/comments?
