WINSINN 40mm Blower Fan 24V, 3D Printer Micro 24V Fan Blower 4020 Hydraulic Bearing, Brushless Cooling 40mm x 20mm 2PIN (Pack of 4)

Ne fais pas trop de bruit dans le socle d'une imprimante 3d, le souffle est très correct et le prix est un peu plus cher mais la livraison est rapide

Ottima aspirazione e fuoriuscita.Forse un po' troppo grosso il foro di uscita dell'aria.

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。

I bought this fan to replace the stock parts cooling fan on my CR 10S Pro V2 because I'm too impatient to wait on the replacement Creality one that's coming from China. It's a bargain for four 4020 fans and so far it's been doing the job as expected. My only gripe and the reason I removed one star is because this fan is so incredibly loud compared to the original fan. I'll probably swap it out as soon as my replacement arrives, but it's always good to have spares.

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.
