check thermal paste, reapply if needed
check fan whether pin properly or not
check cable management and also flow of fan, exhaust and intake
82C is still acceptable, in daily moderate usage temp shouldn't/won't be as high, but make sure install aftermarket cooler be4 overclocking
Thanks! I'll change the paste when i get the new cooler this week. Do you have any tutorials or videos i can watch so i know how to apply it the best?
