My M2 MBA doesn't have a fan but literally smokes the majority on Intel systems which are space heaters this time of year. Those legacy x86 apps don't really exist for the majority of people anymore.
If you place 1mm thermal pads between the sinks and the case, the CPUs/GPUs won't throttle as readily. At least for my M3 MBA (check your actual clearance).
I replaced a MacPro5,1 with an M2Pro — which uses soooooo much less energy performing similarly mundane tasks (~15x+). Idle is ~25W v. 160W
