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.
- ProllyInfamous 8mo agoIf 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

- ProllyInfamous 8mo agoYou 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.
- zozbot234 8mo agoIt's going to get hot if you peg the CPU/GPU at 100% for long enough. Just a matter of physics.
- ProllyInfamous 8mo agoThe casebottom of my 15" MBAir has never exceeded 32°C — and that's sitting on a bed. Just a matter of physics: conductive case has orders of magnitude more thermal mass. It also helps that Apple Silicon processors consumer orders of magnitude less power than most competitor OEMs. Pegged out the entire machine uses less energy than my former notebook's GPU, alone.
