WINSINN 40mm Blower Fan 24V, 3D Printer Micro 24 Volt Fans Blower 4020 Hydraulic Bearing, 40mmx20mm 2PIN (Pack of 4Pcs)

I used these for fans inside a cosplay helmet to help from the lenses fogging and too help keep me cool, and they do just that. I have them hooked up to a 3 AA battery pack and they last for a good amount of time. They are a little noisy and I did have to create a cover to keep my hair from getting caught in them, but that's due to the application I utilized them for and not any fault of the design or manufacturing.

Very impressed. I am running them off a USB port at only 5v so they don't move a ton of air, but it's enough for my application and they are dead quiet.

Compared to the stock Creality 4020 blower fan these were noticeably louder (~15db louder when measured next to the fan). There was also a weird sound/vibration/whine on lower power (50%). Another issue I had was that these were not wired correctly out of the box. I had to flip the wires in order to get it to work with my printer which was inconvenient. I only tested one fan so it may be a dud. Overall these are inexpensive fans that’ll probably get the job done, but are louder than what they are replacing. Not sure how durable they are, only time will tell. Might be worth spending a bit more money for fewer fans that are quieter and wired correctly.

Looks like a good fan for something but not what I needed. I think they are for computers

I have heard really good things about this brand and since one on my printer went out i decided to give em a try! UPDATE....I actually got around to installing these and they worked out great! much more quite then the originals and run super smooth. No regrets and will definitely be ordering more when the time comes!

Purchased to put a new blower discharge nozzle on my Artillery Sidewinder X1. Easier than trying to break the glued on nozzzle from the stock blower to reuse it. I tried three of the four Winsun fans and they all vibrated like crazy while running, one had clear failing bearings since after running for about 1-min. It started squealing. The stock blower does not vibrate while running at all. Sorry, but these fans are trash. To bad I pitched the box or I would send them back.

I bought these for a custom cooling system I was working on. I was surprised by how quiet they are. -Now the PSU is the only noisy item left-

Well, they worked, but at first they didn't. I couldn't figure out why they weren't coming on when I noticed that the red (positive) wire and the black (negative) wire on the fan connectors where not in the same positions in the female connector that I had purchased here on Amazon. I had to change every black and red wire on the fans since there were fewer to change than the 30 other connectors.

Son pequeñas turbinas de 40x40x20, un tamaño contenido con bajo nivel de ruido y un flujo de aire medio. Los uso como inyectores de aire para el hotend de impresoras 3D. Son económicos y vienen bien presentados en un estuche de plástico transparente. incorporan cable de 30cm con conector JST. No se cuanto durarán pero no me preocupa, tengo de repuesto. Los volvería a comprar.

残念ながら振動大きめ。 しかしながらテープを貼り付けてだいたいのバランス取りして振動は減らすことができました。 実際には PWM で 50% 程度の回転数で使用しているため、バランス取りしなくとも振動はそれほど気にならず。 実用上は問題無し。

Die WINSINN 40 mm Gebläse Lüfter sind eine hervorragende Wahl für die Kühlung von 3D-Druckern. Mit einer Größe von 40 mm x 20 mm und einer Spannung von 24 V bieten diese bürstenlosen Lüfter eine zuverlässige Leistung, die eine Überhitzung während des Druckens effektiv verhindert. Dank des Hydrauliklagers arbeiten die Lüfter leise, was für eine angenehme Druckumgebung sorgt. Die Installation ist einfach dank des 2-Pin-Anschlusses, was die Integration in die meisten Drucker problemlos macht. Allerdings gibt es einige Punkte zu beachten: Einige Nutzer haben angemerkt, dass die Luftzirkulation bei hohen Druckgeschwindigkeiten variieren kann, sodass in manchen Fällen mehrere Lüfter erforderlich sind, um optimale Ergebnisse zu erzielen. Insgesamt bieten die WINSINN 40 mm Lüfter ein gutes Preis-Leistungs-Verhältnis und sind eine sinnvolle Ergänzung für jeden 3D-Drucker, der auf effektive Kühlung angewiesen ist.

４個とも無事動きました。 小さい商品なので風量は、あまり期待しない方がいいです。 音は、さほどやかましくないです。 5VのＦＡＮですから、こんなものでしょう。 耐久性は、使い込んでないので分かりません。

Los ventiladores nos llegan en una caja de plástico. Estos están fabricados en plástico de calidad menojarble al igual que sus acabados ya que presentan algunas imperfecciones producidas por la inyección de plastico en el proceso de fabricación, nada que no se pueda arregla con una lima o lija. Los he usado para una impresora 3D en la cual quería reducir el ruido de reactor que tenia de serie y la verdad que el cambio se ha notado, pero aun sigue sonando con este ventilador. Pero es lógico en este tipo de ventiladores de turbina, al llevar mas palas y su forma, esta genera más ruido y es inevitable. Al cocerlos sobredimensionas, el doble de anchos, me permite bajar un poco el voltaje y así las revoluciones y el caudal es suficiente como para enfriar el filamento según sale del mozzle por lo que disminuimos su ruido en mas de la mitad. Espero que esta reseña te haya sido útil 👍.
