True Bruce , but it shouldn't get too hot. My Pismos heatsink even after 1 hour of moderate use on a summers day will never get more than hot to the touch if I whip the keyboard off and touch it with my finger ( OK it is still pretty hot to touch but I wouldn't burn a finger , put it that way ). Anything more than that and I think MacDirk has more serious issues causing this problem.
Are all vents in this machine free of dust ?
