GDSTIME 2pcs 50mm Blower Fan 5V Centrifugal Cooling Fan 50 x 15mm 3500 RPM Case Cooler for 3D Printer Laptop Motherboard Exhaust Ventilation

Great fans, not too loud either. I don't know if there are better 24v fans out there, but this is the most readily available "recommended" brand for 3d printer use alongside sunon or delta and you can certainly do much worse

I got these to try on my 3D printer for part cooling, it's early days but so far I'm impressed! They are quite than the Winsin version and kick out a decent amount of air, they also work fine using PWM on them.

My printer's motherboard outputs 24 volts so it made this blower fan perfect for the job. One star off because it is a little louder than i thought it might be but not bad at all.Definitely produces better prints now with the extra airflow so well worth it.

These little fans are noisy and way way too expensive, would be fine at half the price.

The fans work well so far. Using one of them in my 3d printer for part cooling it provides sufficient airflow seemingly and isn't too loud at all. Can recommend these for others needing a 4010 blower fan.

Does what it says on the tin.

Missing connectors, so can't even test it. Wires super glued to the top of the case.

Used these on my cr5 pro H printer to upgrade the stock fans. Really high output of air and very smooth.
