i own a low end 2.4 ghz penryn mbp, i am very impressed with the performance i get from it, yerp, i know about the gpu glitch i use smc fancontrol all the time to keep my system cool, Is there such a thing as over cooling? i played a few games with out using fancontrol but found that the system was getting so hot i bet i could cook an egg on it. i usually keep the fan going at 2500 or 3000 during normal use depending on the weather. this keeps the system at 38 - 45 degrees Celsius. when playing a game i put the fans on 4500 - 5000. this keeps the cpu between 45 - 55 degrees Celsius and the gpu at 55 - 60 degrees Celsius. this keeps the system very cool is this over cooling cause i know apple only revs the fans once the cpu and gpu reach 70 degrees Celsius. thank you all!!
