Great product at a great price
So I will say they are quieter than the ones I had on before quality-wise I've already put 200 plus hours on them still working like a champ

3D printer usage ok at 100% fanspeed
These things move some air!!! They are rather loud but if your looking for this type of fan your probably not worried about that. Very good fans for the price. Only complaint I have with them is at less than 100% fan speed they have a high pitch electronic squeal. At 100% though they will cool that plastic right quick! definitely recommend if you have then in another room/garage while in operation.

2/4 died
Works well for sure but they don't last long on my 3D Printer. The first one finally died about a month but the second one out of the bunch died within a few days. Now I'm left with two and going to be looking for other brands.

12V NOT 24V SENT. Check before install
After going through all the trouble of installing 4 of these, they instantly shorted. when I went to look at what the issue would be, I noticed the stickers on the back say 12V. Now I have to remove them from an enclosure I made, and drive to my local returns place to get my money back. Next time I'll order quality parts.

Moves a lot of air and are quiet, even at lower speeds.
They all are well made and work great. Move a lot of air and are quiet, even at lower speeds. The wiring polarity was all soldered correctly.

Works great but needed to swap hot and neutral.
Used these to upgrade my Monoprice Maker Ultimate, which uses 24v fans. They didn't initially work, but swapping the hot and neutral wires in the plug got it to work. They spin nice and quietly, and the cooling is great!

Not as described, low speed - negligible airflow
Web description is not accurate. RPM described in Amazon listing is around 5589 RPM but actually it spins way lower even at full voltage (24v) and airflow at maximum speed is negligible. If you are planning to use for 3D printing part cooling fan, this may not be the right product. 2 Fans out of 4 I received also had lot of wobble making them vibrate a lot when in use.
