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

Size as purchased, power and airflow seemed reasonable. Not quiet, but not noisy.

I replaced the stock blower fans on my Creality Ender 3 V3 KE with these WINSINN fans, and the difference is remarkable! They are significantly quieter than the original fans, making a huge improvement to the overall printing experience. The airflow is also noticeably better – I needed to update the First Layer Bed Temperature to a higher setting to ensure proper part adhesion. Installation required a bit of modification; I had to cut off the existing connector on each fan and solder on the connector from my existing fans. Since I only needed two, it’s great to have the other two as spares at such a low cost. Highly recommended for a quieter and more effective cooling system!

This fan is a compact and efficient cooling solution suitable for various electronic and industrial applications. Its 50mm size makes it ideal for tight spaces, while the 5015 model ensures a good balance of airflow and quiet operation. The 24V power supply offers reliable performance, and the fan's build quality appears durable for long-term use.

These fans work fine, but for 3D printing where the print head moves rather fast the motor shafts have too much play in them, resulting in some clicks when it's moving. They get underclocked to run at 40% to provide the same cooling levels as the 4015s it replaces, so they're nice and quiet when the machine is cooling down. The clicking noise is driving me crazy though.

This is a great, direct fit replacement fan for a Vicks small room humidifier. Our humidifier fan was noisy, grating and then just quit working. Buying one fan costs more than a box of 4. It is simple to open the base of the humidifier, then remove a small cover that goes over the circuit board of the electronics. Remove the old fan, I used the two small pieces of foam insulations from the old fan that absorbs vibration, there was enough adhesive left and they stuck to the new fan. Unplug the old fan's connector from the circuit board, and simply plug the new fan's connector in. New fans come with the the connector, it fits! Replace the cover over the wiring. Put the base back together and you have a quiet, working fan. If you test it before filling with water - remember, there is a float that completes the completes the circuit. If you plug in and test the base upside down the fan will work, turn it over and float drops as if the water tank is empty and the fan stops. Fan works and I have 3 extra!

Works amazing for my replacement print fan for my modded Creality Ender 3 S1 Plus and modded Creality CR 10 Max. It is a little bit noisy, but that is to be expected with a high volume fan like this.

I got these to go in a printable duct for my Ender 3 v2 printer. Of the two installed, one of them failed a week in due to a wire pulling off the board on the fan. It was no issue for me to get my Hakko soldering station out and fix it, however it never should have been an issue in the first place. It appears the traces on the board had started to de-laminate from the original soldering job heating the cheap PCB too much. To clarify, I did not have tension on the wires, and they were secured in the groove and notch on the exterior of the fan. This board was probably de-laminated with I got them, however it took a week to break in use. I'd expect this to be a common failure mode and could be checked for by halfway peeling off the sticker on the back of the fan near the wires.

These little fans plugged right in and solved the problem!! My humidifer which has ran with no leaks or any problems for YEARS!!!! Awesome humidifier! unit is made by vicks, model v4600D1. Saw it done on a YT channel with a link to these fans. Don't remember the name of channel. Just search for it. The fans just plug right in and your back in business.!! Only 6 tiny screws on bottom of humidifier to loosen. When putting back together just put the humidifiers humidity control knob back in it's seat. It's not hard at all to change these little blower fans. The fans came in a small box quanity of 5. The description of fans( on box) Winsinn 5015 24V DC Blower Fan US. There was a bar code label just above the previously mentioned description of the Winsinn fans on the side of small box. The barcode is B079BPS9Q8. It may be pertinent, or just for shipping IDK. Hope this helps someone.

El ventilador funciona a la perfección en mi impresora Prusa I3, el cambio fue limpio, lo único malo fue que el largo del cable es muy corto (ya sabía sobre ese detalle desde antes de comprarlo), pero nada que unos cables bien soldados no pueden arreglar. Leí muchos comentarios sobre el ruido pero la verdad no estoy de acuerdo con ninguno de ellos, el ventilador no hace ruido en exceso, cuando imprimo no se percibe. Excelente, volvería a comprarlo.

Comme l'indique le titre ce sont de bon ventilateur et très silencieux même à 100% Comme d'habitude avec ce genre de ventilateur, pour ceux en marlin, n'oublier pas d'activer la ligne Soft_PWM pour empêcher le grésillement, pour les autres firmwares, à vous de trouver la bonne fréquence, je la cherche encore ^^ Ils valent leurs prix

they really BLOW

product is too small and speed of fan is too low

I bought these as i need to add some stronger fans to my 3d printer. The airflow is way too much i actually need (only using then at a speed between 50-70% of its maximum), but rather have the option to increase than not. It significantly improved the overhangs of my prints. And its not noisy as some other fans I've tried.
