2-Pack 40mm x 10mm 4010 Dual Ball Bearing DC 12V Brushless Cooling Fan, YDM4010B12

Good value, quiet fans. This is the second replacement fan I've had to install on one of my Creality Ender 3 V2. First replacement from another supplier lasted 3 weeks, was noisy from the beginning, got worse and finally seized. These ones so far are quieter from the first time of turning them on, and so far no issues at all. Providing they last more than a couple of months then I'll be happy.

Good little fans. Bought to increase the air flow inside my pc, have worked very well. Very impressed, would recommend.

Why did you choose this product over others?: Size, it fits between the fly screen and the outer grill on caravan fridge exhaust. Used to boost flow.

Those have a slightly high pitch, but are less noisy than the original Flashforge ones. I did try to replace the ones in the extruders (Creator 3) but the very quiet models won't give enough airflow resulting in poor cooling off the hotend, which means a nasty clog. Had never happened with those, so it's good for now

I'm using these on a Monoprice Maker Select Plus. They're audible, I mean they sound like a harrier taking off. Maybe it might be worth a step-down converter, or just reducing fan speeds. But they do what they're supposed to--they move air.

Sorry, but I'm rather disappointed with the noise level which is practically identical to the original fans that came with my Ender 3 Pro. I measure 55db with the decibel meter on my iPhone around half a metre from the machine, which is the same reading as before I changed the extruder fan and the motherboard fan. Other than that, the fans work fine. All the hassle of changing the fans for absolutely no gain.

it works as a replacement for a cooling fan for my printers board. sound wise very simular to the old one before it failed.

Sadly I had a faulty set one the wire fell off the fan connection as soon as it was fitted.

Je les ai achetés pour remplacer les ventilateurs de mon ender 3 v2. Ils sont arrivés rapidement dans une enveloppe à bulles. Ils sont très silencieux et comparables à un sunon que j'avais déjà acheté mais ce dernier est 2 fois plus cher. De plus ils sont en 24v donc rien à faire si ce n'est une soudure sur les câbles d'origine car ils sont livrés avec un câble de 10cm environ.

Petits, costauds mais bruyants. Je ne sais pas d'où viennent les 26 dB mesurés. Pas possible ! (26 dB c'est pratiquement le silence et ce n'est pas le cas)

presi per sostituire quella presente di fronte all’estrusore della mia stampante 3d, funziona egregiamente, non è un mostro di silenziosità ma la omologa sostituta non era meglio. a 24 volt e con grande efficacia il rumore fa parte del pacchetto per una ventola così piccola

The wire length is only 6 inches from the connector to this 24v fan (40mm x 40mm x 10mm). The 2 pin connector was the right size, but I needed at least 7 1/2 inches to reach the connector on the circuit board. I purchased it because it is reported to be quiet and QUIET IT IS!! I cannot hear it at all and if my APC BackUPS power supply had not pass its self-test, I would not know it was on. Really! Rather than return it, I decided to splice the wires with that from the original fan that caused a startlingly loud alarm on my APC BackUPS 900 battery backup power. In 2016, I purchased a uxcell DC 24V 0.09A replacement fan because the original was making noise and I feared just such a need. But the uxcell is way too loud with a constant humming noise. So I order this brand to see if it was quieter. It is inaudible! If my APC battery backup UPS hadn't passed its self-test and my unplugging it from the AC outlet to test it's battery backup capabilities, I would not know it was on! It was worth the effort to splice the connector (soldered with shrink wrap insulation).

Initially sent wrong voltage but sent back and they sent correct voltage(5 V). Worked fine.
