This build uses a i3-N300, which is evidently a 7W chip.

Is there a sense on how much cooling this provides? Could you strap it to a 30/45/65W CPU and otherwise be fanless?

The manufacturer claims 4.25W of net cooling (5.25W cooling, 1W power consumption) for the Airjet Mini, and 8.75W (10.5W cooling, 1.75W power consumption) for the Airjet Pro.

Nuts. 5W of cooling might as well use a standard heat sink.

A heat sink of the same weight as this device might not be able to remove 5W of heat.

Why is the weight important here?

I buy mini PCs, and I've rejected mini PCs in the past for being too heavy, particularly, the Akasa fanless cases for Intel NUCs where the entire case is made of aluminum and functions as a heat sink.

(The weight matters because I commute with my mini PC.)

It's shocking how hot 5 watts can get a hunk of metal. As the airflow lowers more metal is needed.

The LTT link in another comment here goes into details. Iirc it's about 5w of cooling per unit in its current state
