I'm constantly running my MBP to it's limit (getting a newer one soon), by that I mean the CPU temp is around 80* most of the time with the fan up at 6000RPM. I plan to do the same with the next model I buy, just because that's what I need to do for work. My question is basically, will this reduce the life of the machine at all? I've read about mainboard failures and graphics chips dying. I run my machine with an external monitor and a fridge magnet on the side to keep the internal screen off, so it's only pushing one screen at a time + getting cooling from being open (clam shell mode sucks).
