The temperature of the laptop is an accurate enough replacement for fan noise (if you use it normally, not in clamshell mode). I notice that I've become far more sensitive to subtle temperature changes in my M1 than I used to be in prior fan-cooled laptops. Probably because the fan tends to come on before the machine heats up to the touch, so temperature was a weak, secondary cue.
