How are standard computer fan screws called?

Apparently they're 7/32" /5.5mm self tapping screws, though some places say they're 3/8". I'd note given their design, you should have some leeway since the screws cut into the plastic, to use different threads or slightly larger screws.

"Plastic thread cutting screws" is the technical name and are not classified other than by diameter and length.

Like wood screws they do not designate a thread per inch like other screws or bolts

I have a small drawer full of them I have salvaged from discarded items, plastic thread cutting screws are handy to have around since most everything is plastic these days.

In most stores and retailers you'll find them exactly under that description.
"PC fan screws", "Case fan screws" etc'.

If this is a more academic question, I'd love, too, know if they have a special type name, but I doubt it.

I could be wrong here, but to me they look like euro screws (drawer runner screws).

This listing looks to be the same size as the screw I was comparing to:

And the title of this Alibaba listing seems to agree with me:
