Thats surprising you haven’t heard the fans. Must be the use case. There’s a few games that will get it quite hot and spool up the fans. I have also noticed its got somewhat poor sleep management and remains hot while asleep. Sometimes I pick up the computer for the first time that day and its already very hot from whatever kept it out of sleep with a shut lid all night.
Not sure what app you’ve installed to make it do that, but I’ve only experienced the opposite. Every Windows 10 laptop I’ve owned (4 of them) would never go to sleep and turn my bag into an oven if I forgot to manually shut down instead of closing the lid. Whereas my M1 MBP has successfully gone to sleep every lid close.
The Windows 10 image my employer uses for our Dell shitboxes has sleep completely disabled for some reason I cannot possibly comprehend. The only options in the power menu are Shut Down, Restart, and Hibernate.
If I forget to hibernate before I put it in my bag it either burns through its battery before the next day, or overheats until it shuts itself down. If I'm working from home and get up to pee in the night, I often walk past my office and hear the fans screaming into an empty room, burning god knows how much electricity. Even though the only thing running on it was Slack and an editor window.
It's an absolute joke of a machine and, while it's a few years old now, its original list price was equivalent to a very well specced MacBook Pro. I hope they were getting a substantial discount on them.
