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

  • Caution: don't put the laptop in your lap if you've done this. There's a reason it doesn't ship like that out of the box.

    • You already don't want notebooks sitting on your lap (safe radiation exposure limits from WiFi / Bluetooth), which is why they're no longer referred to as "laptops" (by OEMs).

      But if you're commenting about temperature / burns — the bottom of the MBP doesn't get noticeably warmer (at all), likely because the large metal case is such an efficient dissipator/sink.
