How safe is it for the long term safety of my MBP to run at high load for the majority of the time. I don't game, but I do run some scientific applications that cause my MBP to run at high CPU/GPU load for a considerable amount of time. The temperatures are always within the max temperatures allowed (CPU is usually between 55 and 80, but almost never above 95 C and the GPU is similar but usually never above 85 C, I think). Does running the MBP at high but technically "safe" load add any risk to the longevity of my machine? When I'm at work, I usually run in clamshell mode too, and I feel like this causes a little higher temperatures. I can always open the lid to reduce some of the heat buildup if this is a problem.
