Lately my iBook has begun to be not so silent as it used to be. Everytime I open it and it sits idle, it sound like the processor is running, not whining, or ticking like it usually does when working under full load but more like a humming working sound. Not more than 5 minutes ago the fans kicked in and I opened Temperature Monitor too see that the processor was 65 C when just streaming movies from break.com! O_O I put it to sleep and returned. When I opened it, it was a mere 40 degrees C but then it started climbing again and now it's 60 and climbing just by writing here on MR!! Wtf is going on? It shouldn't be this hot just idling!? I have had it up to 65 C before, but that was using quite a lot of proc intensive apps open... Edit: wow, just opened Activity Monitor, the cpu was at 100% working on Firefox!????!! That explains it of course. Weird though.
