2006 Intel Macbook, runs Snow Leopard, has a tendency to run its fans high, sounds like a weak hairdryer. I've checked activity monitor and terminal. Things seem fine. While typing this however activity monitor shows a lot of system usage. For some reason I'm not suspecting my browser (Camino), and it happened while I have had one tab open. I've tried resetting the SMC, worked then it came back. I've tried the printer queue thing but I can't find anything. So far the most logical conclusion I can draw is that it could be the surface but even then on a stable solid surface it runs high. I'm seriously considering taking it into Apple because this is getting repetitive. I can understand fans running high when I'm doing intensive processes, but happening while playing music and checking my e-mail? Help would be greatly appreciated. I want to try all options before I have to really take it in.
