ANVISION 2-Pack DC 24V 40mm x 10mm Brushless Cooling Fan, Dual Ball Bearing, 2 Pin

I used these for a hot end with a 70w heater cause it was giving me issues on the stock fan. These do move a bit more air. Better than a overpriced poop brown fan which yes is quieter but moves far less air. Shouldn't be in the same room as melting plastic to begin with so loudness isn't a issue. Definitely has more static pressure coming off the front than most of the other 40s I've tested. These will end up being my go-to when replacing fans in the future

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).

I know that these aren't silent fans but pretty dang close. This fan was a perfect fit for my Ender 3 V2 and my Ender 3 Pro. It was easy to install and worked from the very first power up.

These are great fans for the money, the hub of the fan Is smaller than the stock fan, so the blades can be a bit larger. The airflow over my 3D printer’s hotend is definitely much stronger with these. Overall very happy with these.

No issues using these on my Ender 3 Pro. Used one on a CR6-Max with a shroud to try to help with clogs. Fan worked great but that printer was a hardcore fail. I debated going Office Space on it but decided against it due to fears of being cancelled by my wife.

The fans themselves are amazing, i lubed the bearings with superlube oil, and you can barely hear them. The quality seems decent from the 2 i recieved, but i am not sure how the quality control is. Only downside is how short the cables are. In short terms they were a great motherboard and hotend fan replacement for my ender 3 v2, these will also work with any other variant of ender 3, as long as its a 24v connection. Overall very satisfied and will be ordering more when i need to replace them again in the future. If you are going to replace your hotend fan with one of these make sure you are able to reliably solder a nice joint, i reccomend practiceing on similar size wire before, or even just use a connector with low temp Sauter.

I've had these for a few days now and have done a fair amount of printing on my Ender 3 with one of them. They're far quieter than either the stock fan or the allegedly quiet fan I replaced it with, although they do not move quite as much air as my previous fans. They seem to do a good enough job keeping the hot end cool though, so it's a good tradeoff. They're not completely silent, but they're also probably the quietest fan on my printer now so it wouldn't accomplish much for me to get a quieter fan unless I replace the others first. Overall, very happy so far. If they hold up to the many hours of printing I intend to subject them to, they're five stars all the way in my book. My only gripe is that the label is sideways because of the orientation of the fan mount on my printer. ;-)

Used to replace motherboard and hotend stock fans on Ender 3 Pro. Install for motherboard fan replacement is plug & play; wire length is perfect. Install for hotend fan replacement requires splicing into original fan wiring harness. These are great and really reduce a lot noise. I have run them 300 hours and they still remain quiet. If you have an Ender 3 Pro and want a printer as silent as a ninja assassin, combine these with the Creality Silent Motherboard and skip the TL Smoothers and motor dampeners. Downside is, you’ll have to actually look at your printer to know if your print is complete.

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.

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

3D プリンターで使用。 DC-DC で電圧を低めにして使用、風量も十分で音も静かです。 DC-DC コンバーターも Amazon で購入。

Less noise, less vibration than the original, the wires indeed they are shorter than the original on Ender 3 V2, BUT … if if you are good at soldering and you have a fine tip on your iron, you can sold the old wires, from the whole harness going to the motherboard, directly on fan. Remove partially the sticker on fan and you will have access at two soldering points (two short wires ended with a conector are soldered already) . Remove those two wireas and in their place you will sold the wires from your machine. Be careful at polarity. Put back the sticker. Done. Fixit with the same screws from the old one and close the shrowd, then attach the tireups.

Better than the original fan which failed a couple of days after purchase (manufacturing fault). Same number of blades as the original (7) and noticeably quieter than it. Cables aren’t long enough for a straight swap by any means, but was able to easily solder the original printer wires to the new fan no problem at all by slightly peeling back the sticker from the motor centre (magnifying glass helps at the contact pads are very small). Working well, with a few 3D prints done already. Worth the extra couple of quid over the many other options out there, just for the ball bearings rather than sleeve.
