They discuss it in some detail in one of the Voron Live talks - I think this one, which was the announcement video for Stealthburner. Lots of CFD combined with manufacturability testing and aesthetics mixed in too.
Edited to add: oh, that’s the hot end fan. I don’t remember if they discussed that or just the part cooling fan, but the video is an interesting watch either way.
