WINSINN 40mm 24V Fan - Dual Ball Bearing 8000 RPM 4020 Cooling Fan Replacement for 3D Printer/Industrial Equipment, 30cm Cable with XH2.54-2PIN, Brushless 40x20mm (4Pcs)

Works perfectly for my Bento Box (air purifier) in my 3D printer. Running two of them off a 1A supply with plenty of pull to clean the air. Very quiet as well. Definitely an excellent choice for small cooling and filtering projects.

This replaced the stock 4010 heatsink fan on an Ender 3 Pro. It’s definitely quieter than the original while moving more air. It’s not quite as good as a similarly-sized Noctua, but they don’t make 24v units and I didn’t feel like adding a buck converter, especially since the power supply fan is much louder. With that success I also replaced the heatsink fan on a CR10S Pro where it’s working just as well. The picture attached was taken mid-installation so you can see it better. Now I have two spares in case one dies or (more likely) I get another printer with a 4010. If you don’t have a JST connector kit, I strongly suggest buying one. Sure, you can solder the wires, but using plugs gives you a lot more flexibility with swapping out fans, wiring placement, etc. Pro tip: use hot melt glue after you solder the wires to the socket to secure and insulate them. You can see mine in the background of the Ender 3 pic.

Update: Seller definitely honors warranty. I was sent more fans to replace those with broken wires. After several months, the fans (40x20 24v dual bearing) are doing great. With the stock Ender 3 V2 parts cooling fan, it was always on 100% to move enough air. With these fans on a dual Fang setup, I never have to set it above 15%, so they're MUCH quieter than stock. Had to remove a star for the garbage insulation and brittle wires. If you're going to use them on the hot end you absolutely must reinforce any part of the wire that moves repetitively during prints, otherwise the insulation and wire will eventually fatigue and break. I had to use a combination of hot glue and heat shrink tubing to use as flexible stress relief. ----------------------- First review: Bought a 4 pack, and already two of them have had broken wires. Whatever they use for the insulation on the wires is brittle and garbage. Will update if seller honors 24 month warranty.

Used this in an effort to solve heat creep issues that suddenly (and inexplicably) popped up on my Ender 3 Pro. Long story short, it worked. Fan is WAY quieter as a bonus. I'd say less than half as loud as the stock hot end fan-but it does have kind of a low humming sound that's different than the stock fan. Not bothersome but just wanted to note it. NOTE: Does NOT work with the stock fan shroud. I ended up drilling holes and mounting it on the outside of the stock shroud but I still had heat creep issues. So I finally printed the Hero Me fan duct (see pic) and the issues is solved. LOVE this fan. Plus now I have 3 backups. I have used this brand in the past and they tend to fail after about 4-5 months of heavy use but we'll see if this model is more durable.

Just outfitted five of my printers with the WINSINN 40mm Fan 24V, and the results are striking. For a modest price, this fan has provided an excellent solution to combat overheating while maintaining a remarkably quiet operation. Ease of installation and the low-noise dual ball bearing design make this fan a standout in its category. Now, my 3D printing sessions are not only more efficient but also significantly quieter, contributing to a more pleasant working environment. For anyone seeking a cost-effective yet high-quality cooling solution for their printers, the WINSINN 40mm Fan 24V comes highly recommended. It's a small investment with substantial returns! Score: 5/5

I ordered these fans to replace the noisy creality fan on my Ender 5 Plus. They were still louder than expected, but they were quieter than the stock fan. One out of the 4 fans in this pack had a vibration in it. I contacted Winsinn and had a response the same day. They apologized for the faulty fan and immediately is sending out a new 4 pack of fans to me. Overly generous and appreciated. 5 star customer service. Will buy more of their products in the future.

Using to cool 2a stepper motors in a heated enclosure. Prior to installing these fans my motors would over heat and cause severe lose of steps (“layer skips”). Since intalling that issue has disappeared completely. Enclosure used for ABS, PC, and cast plate nylon. Tons o air flow and there is no issue with seats being caused from the fans, although you can feel the air coming from them at about 8 inches away.

This is a solid product, great manufacturing quality and assembly. I Installed it on a 3D printer and it blows really well, really like it. As it is powerful, don't expect it to be quiet as a wispher, but is not loud.

Sehr gutes Produkt Set

Produto silencioso e duradouro. O pack vem 4 que irá durar por muito tempo.

This fan has dual ball bearings. It is also a thickers fan so make sure you have longer bolts. Because it is powerful is has a higher noise level.

Good cooling fans. Really quiet.

Tra tutte quelle che ho provato in questa fascia fi prezzo è la più silenziosa ed efficace.
