I have an Acer Predator 17X. Long story short, the thermal compound on the CPU degraded and caused extremely high temps. I finally took it apart and replaced the thermal compound, the new temps are nice and cool in the 60's Celsius. The temps were 90 Degrees Celsius for about 5 months of daily usage. Is my system damaged? I know that the CPU will throttle when temps are too high, but is actual damage likely in this situation? It seems to work good, but will it ever be as good as it once was?
You should be fine. High temps *can* cause some degradation, but you would notice it already.
