I own an M1 Macbook Air. At its hottest, it's a fraction of the "normal" heat that my year old Intel based Macbook Pro runs at.
To get the M1 warm, I need to be charging it while also playing an Intel based game like the latest Subnautica, with the machine on my lap. Even then, it's not as hot as my Macbook Pro gets while unplugged and browsing the internet.
