um, 76 degrees F is not hot at all.... so im assuming it is 76 degrees Celcius. in that case it is rather hot. water boils at 100C and your pc is 3/4 of the way there!
have you called apple tech support? im sure they will give you a definitive answer for this... and it also depends on when you bought the machine. there have been cases about the overheating and it is a known issue so you may want to even take it to a apple service provider. so then you can get a technicians opinion.
I think it is worth checking out... i would if i were in your shoes.
good luck,
rob.
