It's pulling the heat away from a concentrated region into a larger region.

Performance numbers reflect the optimization. I personally haven't done it for fear of affecting the battery lifespan (and possibly other components' lifespans.)

Really hard to resist due to its simplicity and noticeable improvements.

I can't say I am tempted. When I played a game on an M1 Air, the underside became unbearably/worryingly hot anyway. I accept it's not for sustained load.

I still have pads left over from trying my damnedest to reduce fan noise on a Dell XPS. Used pads on every hot stop and didn't help.

Thanks for the anecdote. I like the simple, well designed, silent, cool and fanless design.

If I were to need any more performance I'd just swap it out for a newer MBA or a MBP with a fan.
