During basic web browsing, I hover around 80°C (according to SMC Fan Control). When I have multiple apps open Photoshop, Spotify, Screenflow, Chrome, Flash, it can run upwards of 99°C. 1) Is this normal? The bottom feels like stovetop burner sometimes and I literally can't touch it without the heat making me really uncomfortable (no lap use). The fan is also fairly loud running running around 4000RPM. 2) Genius guy told me my MBP may have overheated really bad at one point causing the heatsink paste to melt or something? Meaning my MBP will always run hot from now on. No way to fix that. Is that true? If I get a new MBP, how will I know if I'm on the verge of screwing up the heatsink and stop right before?
