Hi people, Just wondering, since I have my new 15" PowerBook 3/4 weeks now, what the story with the fan is! I only ask cause I've read so much on heat issues and fan noise etc here on the forums, and the fact that laptop fans I've come across in the Dell/HP/... variety are so intense you could use them as a hairdryer. Anyway, in all the time I've had my new machine, the fan has never come on- at least I don't think it has. I downloaded ThermographX and kept an eye on it last night, as I watched a DVD. The CPU temp reached 57C and the Pwr supply temp peaked at 61C, but still no sign of a fan coming on. Is this a problem or has it just not gotten hot enough to trigger the fan? Edit: Sorry, those peak temps in Farenheit are 134 degrees for the CPU and 141 degrees for the Power supply. The Battery was the coolest, at 105 degrees.
