Fanless but Fierce: Why the MacBook Air Stays Cool Without a Fan
Apple’s fanless MacBook Air stays cool using a thick aluminum heat spreader and the metal chassis to passively dissipate heat from the M-series chip, delivering near‑Pro performance for most tasks; sustained heavy workloads will throttle as cooling becomes less efficient. Benchmarks show the M5 Air approaching the base M5 Pro in single-core, multi-core, and GPU tests, though the Pro can still pull ahead in long, demanding sessions. The design traces back to the M1 era, with iFixit noting the removal of a fan, and reviewers acknowledging cooling tweaks exist but don’t remove throttling under peak load.
