3/4 ventilateurs défectueux
Au début, je pensais que mes soudures étaient mauvaises car 3 ventilateurs sur 4 ne fonctionnaient pas.Après les avoir remplacés par d'autres ventilateurs d'une autre marque, force est de constater que mes soudures étaient bonnes...

Quiet Fans, although Not Ideal for 3D Printing
I bought these fans as a replacement for my Prusa i3 MK2.5 part cooling fan. This fan is really quiet and doesn't have a lot of vibration, so I have to say they're built pretty well. Even turned all the way up, they're barely audible. They also don't consume very much power--I measured around 90 mA at full speed.Unfortunately, these fans don't quite move enough air for part cooling in a 3D printer. There's a marked reduction in airflow compared to my original fan; I estimate at least a 2x difference. To be fair, these fans are useful for many other things besides 3D printing, and they seem to be quality fans, so I'll give credit for that.My only real complaint is the lack of documentation--specifically it would have been nice to see some figures for airflow (CFM) and rotational speed (RPM), so customers could better decide if this fan meets their requirements. For that, I'll have to take off one star from an otherwise great fan.
