@Johnkataplease open a new topic for that - dont spam your GPU question into a Laptop question...
but here are 2 pro-tips:
1. ramp up fan speed in driver // will make a little to alot more noise [depends on what you set as Fancurve] and will definitely make your RX580 run cooler
2. undervolt the powerstates 6 and 7 - make sure your card is still stable in games
