Cheaper appearance and 8 desibels louder than the original Noctua fan! Bought a real Noctua to replace this. I didn’t expect this from Prusa:(

It's louder than the Noctua fan, no sleeves on it, but have two soldered and shrink tubed connection after the first 10 cm, and nobody shares the info, I can get this fan with my 3-4. ordered Mk3s+.... Not too nice! Ok, ok, I know, it's cheaper, but the printer price are just higher and higher, and I don't want worst parts for my money.

This is the version B fan which is made by Delta and is a bit noisier than the version A fan which was nearly silent. It is still a pretty quiet fan and likely moves more air which can be important if you use an enclosure.
