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

I'm using both of these on a low cost Sovol 3D printer, and they improved a small problem I had with prints failing due to heat creep, and separately, with poor performance when printing bridged areas. With the two fans installed (and after printing two small adapters, available on printables.com or thingiverse), the printer performance is much better and bridging is especially improved. Note: these fans are rather noisy. If you have an enclosure you probably won't notice, but if your printer is in an office setting, you certainly will. I have some dielectric oil and applied a tiny amount but it did not help. They're just a bit noisy. But it's worth it, given the performance improvements.

You know that little fan in your life that's just... okay? It hums along, doing the bare minimum, never really impressing anyone. Well, the WINSINN 5015 Blower Fan is here to put that sad little fan on notice. This isn't just a fan; it's a statement. A very loud, very confident statement that says, "I am here to move some air, and I will not be stopped." The real beauty of this little powerhouse is its versatility. Yes, it will absolutely make your 3D printer's cooling system perform like a jet engine, as I can personally attest. Just be prepared to dial it back, unless you want your printer to be so well-cooled that it starts printing ice cubes. But this little marvel doesn't stop there. Need to replace the fan in a humidifier? Check. Have a DIY aromatherapy project that needs a subtle (or not-so-subtle) breeze? Done. In fact, if something electronic has a fan that sounds like a lawnmower, this little guy is probably its new best friend. And the best part? These fans are quiet, fast, and reliable. The "quiet" part is the real magic trick. Despite moving enough air to cool a small server room, it maintains a low hum that won't drive you insane. As for "fast," let's just say it gets the job done without a moment's hesitation. And "reliable?" The dual ball bearings mean it's practically ready to work a full-time, 24/7 shift for the next five years. This isn't just a simple cooling component; it's a problem-solver in a tiny, effective package. It's the kind of over-achieving, under-the-radar product that you'll be glad you bought. It’s quiet, it’s ridiculously powerful, and it will probably outlive your device.

One star off for noise, seems 3x louder then my oem on my humidifier. Also the plug is wired reverse of my humidifier, but sold for printer format. Chessy plastic on my humidifier socket, was able to simply force on in reverse direction. Could have just filed down the side pins too. No speed rpm listed.

Success running dual 5015 fans on an SKR Mini E3 V3.0! Get these fans and only these fans (others are weaker and will break themselves and the SKR,) compile firmware with the following changes: Configuration.h #define FAN_SOFT_PWM // makes them not blow up #define SOFT_PWM_SCALE 2 // best for noise #define SOFT_PWM_DITHER // get linear range Configuration_adv.h #define FAN_MIN_PWM 48 // the best value for only a bit of air (lower at your own risk) #define FAN_MAX_PWM 255 // full blast Remove current cooling fan, cut the blue and yellow wires, connect (ideally solder) both fan's red wires to the yellow one and the black ones to the blue one. Attach fans very securely - I highly recommend Thingiverse thing:5750189 for a fan shroud Only need to run fans at about 50% during the print and I'd set the first few layers at 0%, 2%, 10%, 20%, 30%, 50% and keep it for the rest of the print

I bought these to replace the parts cooling fan on my creality cr-200b. I am only using one. So far I have ~200hrs run time on the first fan w/o any issues that leave me concerned. I print a lot of ASA in a heated enclosure so the fan is often in higher than ambient temps (40-60c enclosure temp). I will update this post if there are any premature failures. Noise is higher than the stock parts cooling fan, however it is still relatively quiet (much quieter than the stock hotend fan - I don't even notice it). Air volume is much much higher than the stock parts fan. I've been able to double or triple my PLA print speed, with far better overhangs and bridging. This should be the default fan solution for printers imo. The 4010 just can't keep up during the warmer months.

I had to solder the wires to the fans. I had to modify a fan mount because one fan was a little larger than standard 5015 fan.

Gteat upgrade

I used one these for one my 3D printers, Creality Ender 3 Pro using a custom hot end duct that can be found on thingiverse (thing 4725293) the stock Creality v1.1.4 board is controlling it. The other will be going on a Tronxy X5SA eventually Good: Price, they both work, move a lot more air than the stock 4010 (obviously), not as loud as I thought it would be. Starts consistently at 25% and seems like speed changes are pretty linear as you go to 100% Bad: I don't mind the noise really, but there is a lot of whine when using the fan at anything besides 100%. I tried to compare the noise level to stock but you can't really hear the original over the hotend fan. This is definitely a lot louder than stock at 100% but it's so much more air that it's worth it. Hopefully that whine isn't indicative of a looming issue with the fan since I'll be using it at varying speeds most of the time.

Works as it should, good quality.

Llevo alrededor de un año de uso constante como la ventilación principal de impresora 3D son bastante buenos en este aspecto y un poco ruidosos sobre todos sino estan totalmente fijos en posición, los volvería a comprar sin duda

As someone who loves to tinker and build, these WINSINN 5015 Blower Fans are an absolute gem! I picked up this 2-pack for various DIY projects, and they've exceeded my expectations. The 24V power is perfect for my needs, and the dual ball bearing design is a huge plus, promising durability and a smooth, reliable operation, even under continuous use. They move a surprising amount of air for their compact 50mm x 15mm size, making them ideal for focused cooling without taking up too much space. Whether it's for cooling components in a custom electronics enclosure, improving airflow in a small project box, or as a dedicated cooling fan in a 3D printer setup, these brushless turbine fans deliver. The 2-pin connector makes them easy to integrate into existing circuits. If you're a DIY enthusiast like me, looking for reliable and powerful small blower fans, you won't be disappointed with these. Highly recommended for any project that needs effective, targeted cooling!
