ok false alarm. Epic Games Launcher was doing something in background. I killed that process and fans turned off. the fucked up part is i was on Mobile Hotspot from my phone so it was eating my plan without me realizing.
my hotel wifi tops out at 1 mbps and often drops to ZERO while i get 20 mbps from the phone hotspot, so i have little choice but use the phone.
wish programs like Epic Launcher recognized somehow when you're tethered to a phone and didn't try to like download 100 GB updates until you were back on normal wifi ...
