The old XPS 630/730 bios is written in a way to rev up cpu heatsink fan on power start for a few seconds then quiet down.  ? Dell G5 new bios is pulling the old car engine simulator trick again?  Unfortunately you can not downgrade bios safely.  If temp is good power on and time how long the jet lasts before auto take off (it won’t fly off) and quiet down.
About two weeks ago I got a g5 5000 and its been fine until today where i randomly opened the overwatch ptr and my pc got EXTREMELY loud. After turning off and on my pc, even with no apps open i got the jet sound. I’m litterraly scared to turn it on because it sounds like its gonna explode. I need help
