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

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.

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 ordered these 5015 blower fans as I was looking to upgrade the stock fan shroud on my Ender 3 Pro to a 3d printed one with better part cooling. After my great experience with the WINSINN 4010 Axial Fans, I decided to get these fans. The double fan setup pushes a lot of air, and I have not had any issues with part cooling since I got these fans installed. The package also comes with four fans, so I have 2 spare in case any of them fail, but I have been running them for a couple of months and have not had any issues. Would Recommend.

Like others, I had a Vicks cold humidifier and the fan on that one went bad after about a year. Rather than get a new one ($45?) I tried this. It is a perfect physical fit, the connector works fine and polarity is correct. It took me about 10 minutes to swap out the old one -- pretty basic stuff if you own a Phillips medium sized screwdriver. It does make about 30% more fan noise than the original. And it doesn't quite disperse the moisture (fog) as well. On high, I think it puts out more moisture, but it doesn't loft as well and it wafts and settles around the unit. It does a bit better turned down about 20%. As before, I personally disperse the moisture with a HEPA filter blowing up at the humidifier, so for my purposes, I'm fine with it. Sure was cheap.

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!

The first day one motor died at 24v and it through my project off on the day of presentation... Then no time after tried it again and I had to spin start 2 of the fans. These fans are greatly design but needs help on durability.

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.

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 👍

Bisher habe ich eigentlich ausschließlich Lüfter von Gdstime verbaut, da mir eine hohe Qualität, ein ruhiger Lauf und ein ordentlicher Luftdurchsatz extrem wichtig sind. Auf Dauer wurde mir Gdstime allerdings schlichtweg zu teuer. Da Bambu Lab ab Werk ebenfalls auf Winsinn setzt, dachte ich mir: So schlecht können die nicht sein. Ich habe sie ausprobiert und bin absolut positiv überrascht! Die Lüfter laufen erstaunlich ruhig, bringen eine hervorragende Leistung und bieten ein unschlagbares Preis-Leistungs-Verhältnis. Wer leise und starke Lüfter sucht, macht hier definitiv nichts falsch. Das einzige was man natürlich bedenken sollte, dass der Lüftertyp auch zu seinem Vorhaben passt, bei mir wurden sie als Bedfans für meinen 3D Drucker genutzt. Also als Bauteilkühler würde ich sie aufgrund des niedrigen RPMs nicht wählen, aber ich gehe mal davon aus das Winsinn für jeden Einszweck Lüfter anbietet.

Comprate per una stampante 3D. Rumore molto sopportabile (quasi silenziose), sulla carta la qualità è ottima (doppio cuscinetto), attenderò che si rompano prima di aggiornare la recensione. Se state leggendo e non c'è l'aggiornamento sono ancora in funzione.

Great product and cost effective.
