WINSINN 50mm 5015 Blower Fan 12V, 3D Printer 24 Volt Fans Blower Turbine Turbo Dual Ball Bearing, Brushless Cooling 50mmx15mm 2PIN (Pack of 4Pcs)

Purchased for use with an two Ender3 3D printers (using the HERO ME ducts). I tested all four for functionality and then did the single fan setup so I had one for each printer and a spare for each that may, by all indications, just sit in the drawer because the installed fans are working wonderfully. For the first 20 hours or so of operation the fans were a little noisier than I expected but then they settled in and the bearing noise dropped dramatically. I’m told this is fairly common with small ball-bearing devices.

Looks like most people are buying fans for their 3D printers, but it's commonly used as an exhaust fan for humidifiers and aromatherapy gadgets. They don't last forever, especially with calcium buildup. But they're super easy to switch out. Disassemble the base, remove the control board cover. It unplugs from the board and slides out of position. Mine had some foam tape to dampen vibration, and you may want to add some pieces in the same spots on the new fan. I gently removed the tape from the old fan with a nylon spudger and it had enough tackiness left to stick long enough to get it all reassembled. You have a choice of many different fans. If you like your humidifier to be quiet, choose a quiet one. If you want it to work better and don't worry about noise, choose a high speed one. I chose high speed. It works and sounds about the same as when the whole thing was new. It's striking how worn down the old fan was. Before it stopped spinning entirely, it was pushing out less than half of a reservoir of water overnight. Now it's pushing out almost a full one, which is what it's supposed to do. For features, I chose 5 stars for all. It's not particularly loud for its type. I don't know why warmth maters to an cooling or exhaust fan, but it cool mists very well. And I have no idea what sheerness is supposed to mean in this context... does it make the air suddenly deviate from its course? Yes, that's what even bad fans do. Is it perpendicular to something? Well, actually it is as arranged in the humidifier. So 5.

I have installed 2 of these so far, both in 3D printers. They have great air supply, and were a real upgrade to the stock fans that were included. The folks that sell these fans stand behind their products, and were very responsive to an issue with one fan. I will be buying more of these for future projects as they were just the product that I needed. Planning on dual fans on one of the printers soon, but these are so good, may have to dial them back a notch or print really fast! Lol. Update: These fans have been pretty much running 24x7 for a few months now, and no problems whatsoever - great choice for 3D printers. Threw dual fans on one printer and can print overhangs like never before with all the air being pushed by these. Great buy!

It's a high quality set of fans that effectively cool what they're intended to, keeping it at operable temperatures and they fit near perfectly. They perform exceptionally well despite their small size and low power consumption. They lack easy speed control, however they do have a high value for the low cost. They appear physically appealing and are nice and minimalistic.

These fans move the air! All 4 of my fans are running smooth upon receipt. They are very quiet in my opinion. I was running the Hero Me fan duct with single 5015 fan which I bought from TH3D. I am upgrading to the Petsfang duct and needed a new fan for that setup. I gave these fans a try mainly based on price. I can tell you these fans are better than the TH3D fan which I gave $18.99 for a single fan after shipping. These fans are more quiet and move just as much air. Plus the TH3D fan would not operate at less than 25%. This is not really a big deal but still speaks to quality. I am running the fan fix and it still would not turn on below 25%. I usually run 80% fan and comes on full speed at layer 4. These fans all spin at 10%. I am totally impressed so far. Of course there is no way of telling how long they will last but at this price who cares. They are indeed brushless and run dual ball bearings. I took one apart to verify. All of the reviews calling these fans noisy have probably never used a 5015 fan before. These fans are no more noisy than any other 5015 out there and as I stated these are more quiet than the much more expensive TH3D fan. I had been running 2 4010's and a single 5015 moves much more air than dual 4010's. And if as others have stated you get some bad fans just return them until you get 4 good ones. Buy these fans. You will be happy with them!

I see a lot of reviews talking about the noise level and the wiring being flipped. 0 out of 4 of my fans came with the wiring flipped. They all worked perfectly as soon as I plugged them in. I suspect the people saying this had something wrong with their wiring and proceeded to burn out all of their fans and then complain about it. The noise level is what you would expect from a radial blower fan in terms of air noise. These things do move a lot of air by the way which is amazing. The noise from the coils was a bit loud and high pitched at 500Hz pwm so I adjusted to 100-300Hz and it was much quieter! They are quieter, more balanced, and can sustain a higher speed at a very low power level all while putting out more air than my old BigTreeTech radial fans could ever dream of. Very satisfied.

This really blows. Not in a bad way. I have two fans mounted on my Ender 3 with the Hero Me 6 mounts and at 100% it is too much part cooling for the speed at which I print. I meant to try high speed printing with a Spider nozzle, but had nothing but trouble with that nozzle, so for now, I am using a reliable Micro Swiss and run the fans at 50% or less. All in all, these are great fans which much better cooling than the stock Ender 3 fan for part cooling. It is noisy at higher speeds.

Neither of the 50mmx15mm fans (total of four) were not working. Seen other similar complains below. So if yours are not working neither, they are probably incorrectly wired. I am attaching a pic from a different fan to show you how they SHOULD have been wired. If yours does no look as in my pic, simply re-solder the two wires inverted.

Ich habe diese Lüfter für meinen Elegoo Neptune 3 Pro gekauft und bin von deren Leistung begeistert. Die Lautstärke ist recht hoch, was aber für doppelt kugelgelagerte Lüfter normal ist. Da die Leistung der Lüfter so hoch ist, genügt es nun diese bei 30% zu betreiben, verglichen zu den originalen Lüftern dieses 3D-Druckers. Dies senkt dann auch die Lautstärke erheblich.

Si vous avez la référence du jeux sous entendue, sachez que le mot est tout à fait mérité. L'article à été utilisé afin de répondre aux besoins de mon imprimante 3D et ça souffle !! Aucun des articles n'est défectueux , je recommande.

Does exactly what it should and does it so well, great little cooler 👍

Great product and cost effective.

Muy potentes Los compré para actualizar los de mi impresora 3D y ha mejorado muchísimo con un precio estupendo
