Cooling isn’t really an issue on the M1 models. They don’t run particularly hot and don’t throttle unless you run them full-bore (e.g. synthetic benchmarks with all cores maxxed out) for at least 10 minutes straight, which would be a pretty uncommon thing for the vast majority of the target market of the Air. It’s battery life pretty hard to compete with too. Apple claims 17 hours with typical usage and that mostly holds up in testing.
