WINSINN 50mm 5015 Blower Fan 24V, 3D Printer 24 Volt Fans Blower Turbine Turbo Hydraulic Bearing, 1000mm/39in Cable Brushless Cooling 50mmx15mm 2PIN (Pack of 4Pcs)

This is a great, direct fit replacement fan for a Vicks small room humidifier. Our humidifier fan was noisy, grating and then just quit working. Buying one fan costs more than a box of 4. It is simple to open the base of the humidifier, then remove a small cover that goes over the circuit board of the electronics. Remove the old fan, I used the two small pieces of foam insulations from the old fan that absorbs vibration, there was enough adhesive left and they stuck to the new fan. Unplug the old fan's connector from the circuit board, and simply plug the new fan's connector in. New fans come with the the connector, it fits! Replace the cover over the wiring. Put the base back together and you have a quiet, working fan. If you test it before filling with water - remember, there is a float that completes the completes the circuit. If you plug in and test the base upside down the fan will work, turn it over and float drops as if the water tank is empty and the fan stops. Fan works and I have 3 extra!

Good replacement fan for the Ender 3v2 with Satsana duct. I run them at 40% and it's much quieter than the stock fan. At 100% speed it's very loud but you shouldn't need to run them at 100% on a 3D printer.

1 is still in working order after 26 months. The blowing force is good, but they are quite noisy.I replaced the wires on another one. The solder job was a little sub-par.Even given that I'll be ordering another pack since they worked well for a while.

So far this fan has been great on the new hotend assembly of my 3D printer, it blows a lot of air and is not very loud. Wiring this fan was also extremely easy.

Perfect fan to upgrade the extruded and parts cooling fans on my 3d printer.

these are the cheapest u can get an its always what i buy to have spar fans around for my printers an other electronics. the down side is pretty much everytime i buy them i get a 4 pack an ive always had at least 1 or 2 of them, ive even had all 4 fans have wires that was loose from the solder points keeping them from working, sometimes its just the wires broke loose or poor soldering then theres the more common issue where its not the wire and instead its the solder pad ripped loose from the little electronic board so those fans are trash an go in the trash brand new. i can say if u get a good one or if its one that u can solder the wires back together on they do seem to last. i cant remember having to replace a fan that ive replaced with one of these so they seem to hold up better than the original fans that come in chinese brand 3d printers. but if u dont want to deal with doa fans, spend more money an get a higher quality fan. also i can't say how bad they are for noise cause i have so much ambient noise going on a fan is the last thing i'll heard unless its screaming but i also keep my printers in enclosures so the sounds for them are mostly muffled out an if i do hear anything its usually the noisy a4988 steppers from my older printers so its about half an half silent steppers vs a4988 so fan noise was never really a concern for me but for those who do want to know about this, if u want silent fans buy noctua, if u dont mind tinkering buy these cheapos.

Upgraded ender 3s1 pro with these. Unfortunately the plug is too big so you do have to sadder the wires. But other than that perfect for zuff v4 upgrade.

WINSINN is probably the best at full voltage, quiet, low maintenance, drop in replacement fans! No buck converters, no fuss, no hassle.

MUY BUEN FLUJO DE AIRE, como los utilizo para impresión 3D resultan algo excesivos (puse 2 y van sobrados), por lo que los tengo funcionando al 30-40%, lo que da mucho flujo de aire y poco ruido, y quedan 2 para cualquier cambio que pueda surgir

Works, so far so good!

Used as a part cooling fan in FDM printer. Great airflow - not too noisy - however if the rotor is blocked from turning by a bit of debris, or if the fan air output is blocked, the unit will overheat to the point of melting the fan housing. Also if running with a ambient temperature over 40C under load the fan will suffer damage (rear of housing melts). Power is 3 watts at 24V

Son buenos ventiladores pero el flujo es un poco bajo para ciertas aplicaciones.

They work well, kind of loud. Moves a lot of air.
