You get what you pay for. cheap fans both price and manufacturing.
The media could not be loaded. I purchased a set of these 7 ish months ago and they're all dead or entirely too loud. Wires easily separate from the board. Two of the fans out of package I had to resolder the wires. one of the fans (not one I had to solder) lasted less than a day before making loud annoying screaming noise. The second one lasted a couple of weeks before having to be replaced and the last two started getting loud a couple of months ago but now at a point where they're unbearably loud and need to be replaced. I had purchased a 24v hydraulic bearing set. I need to find some more now but as most of these are just rebranded fans, I'm going to have to do some research to find some good fans that'll last more than a few months.

Descent fans for the price!
These fans work pretty well! I am using them for a small air filtration unit for one of my 3D printers and they move enough air that I do not smell the filamemt being printed! I have two of them pulling air through a hepa filter and a few layers of activated carbon and they still move a descent amount of air! 😁

Great deal for the price. Updated: Don't last.
Update 6/11/20: After 6 months, I am now on the third of the 4 I originally ordered. The first one started whining loudly after about a month and quit spinning completely after about 3. The second also started whining so loudly I couldn't stand it after about a month of use and I had to swap it out for the one I am currently using. Basically, these don't last.Original Comment:I used this fan to replace the internal rear cooling fan on my CR-10S which had begun to scream like a banshee (ever after oiling). So far, this little fan seems to do the job nicely and is much easier on my ears. The only caveat with this fan is that the insets on the mounting holes are about 1mm less shallow than the ones on the original fan -- which means that the mounting screws that came with it are ever so slightly too short. An M3x20 will BARELY engage, but you can probably make it work. An M3x22 would probably work perfectly.

failed bearings after 2 weeks
got these 4pk fans, good fit. started good. so far 2 out of 2 fans I've used, they both failed after 2 weeks. the bearings are bad quality as they start to get nosier, then start to vibrate louder. eventually after about 2 weeks the fan blades can slide up/down...which is bad. don't think the other 2 fans will be any better.

4th time using this brand. So far so good...
Good fan. Installed into a network switch. Reduces ambient sound output and keeps equipment temps down 6 celcius on avg. in that switch. That's a "winn" in my book!
