I have a early 2007 MBP 2.4GHz - I don't like playing WoW on it, because after 10 mins the fans start to speed up. After 15-20 mins the fans sound like they are going full pelt and the noise becomes very noticeable. How are the new MBP's ? I have seen a few posts saying the frame rate is pretty good, but no comments about fan speed / noise. Does the fan noise depend on the graphics chip being used? As noise can be subjective my MBP fans normal idling speed is 2000 RPM (silent), after a few mins of playing WoW the fans get up to 5300 RPM. At that point I am half expecting a voice to come out of the speakers -'Please fasten your belts for takeoff'.
