I'm using iStat and it says that my CPU runs at temps around high 70s, low 80 degrees Celsius for about 10-15 minutes at a time (also says the same for Airport card). It usually takes a while for it to cool down. I always place my laptop on flat surfaces. It does this even during light internet surfing minus flash or any other multimedia...now WITH multimedia use, it reaches the 80s no problem and I just quit the process cuz I don't want my laptop to explode one day. I just wanted to know if this was average and what temps everyone else is usually running at? I'm afraid that if it runs at these high of temps for a long time each time like that, then it may do some damage somewhere... Also, what do you guys use/do to reduce the heat?
