I was taxing my Late 08 15.4" UMBP last night by downloading a two gig movie from iTunes while simultaneously watching an "adult" film of the flash variety, on a 24 inch ACD at full screen. Happy with myself, as well as my purchases allowing me to do such things, I finished my adult feature and got up to exit out, when I looked and saw SMC reporting a 103*C temp with the fans only spinning at 2300 rpm. I have SMC purely for monitoring purposes, and leave the stock fan speed at the 2000 minimum. I was just surprised that the system management would let the computer get that hot and still keep the fans at such a low speed, when I know it's gotten up to 4500 rpm at 90*C other times. Thoughts? I immediately used SMC to boost both fans up to 6000 until it came down to a much cooler temp.
