Relevant quote:

Frore had to painstakingly mill 0.3mm out of the laptop’s lid to give the AirJets a big enough air gap to do their thing, and the company wound up removing the speakers, Wi-Fi antenna, and even the Mac’s internal keyboard connector along the way.

They are stuffing it into a device that was never designed for it.

Absolutely, and it’s super impressive that they were able to. Certainly it can only be improved from here. I just wanted to taper people’s expectations that this was a miracle pill. It’s one step towards proving that these can be used in production, not yet a solution for zero thermal throttling.

They're showing that it's easily doable with a engineering effort to use them from the start. Those things can be moved around and lose none of that functionality.

Its not intended to be a product, it's inteded to be a PoC that shows how it could be theoretically used

They only did this to make room for the demonstration unit, to show how it would affect noise/cooling. A real application would not need such compromise.

This exactly, if Apple was using this tech to cool the air, it would be engineered to fit.

Unfortunately, the Air line I think has been advertised as fanless since the first 11" using super low powered Intel laptop CPU's right? Also they're segmenting their performance tiers by cooling capacity!

The M1 MBA was the first iteration to go fanless, they used ULV Intel CPUs but even those need fans.

I wonder if they would have had an easier time just sanding and polishing 0.3mm away instead of milling

Milling a slot out of a piece of aluminum is not that difficult. It also has a lot lower chance of fucking up a perfectly good notebook part.
