I asked a similar heating question before regarding cooling pads and running CPU intense processes. But I decided to try SMC Fan Control out and it seems to help keep it cooler but I'm concerned about running the fans at full speed all the time. I'm doing Folding@Home (the Stanford protein folding supercomputer project) and running SMP folding. On default Apple fan control the CPU core temps would reach 102-103C before kicking up to above 5500RPM and never going above 5800RPM. Now with SMC fan control running at 6200RPM max it's keeping the cores before 94C which still seems a bit high. As soon as I pause Folding@Home the temps drop to the high 60s/low 70s with or without SMC Fan Control. So will running SMC Fan Control all the time when folding hurt the fans?
