🖨️ 3-Pack Bigtreetech 40x40x10mm Brushless Printer Fans Review

I needed very quiet fans for my 3D printer (Creality Ender 5 Plus). These are silent fans and I think they will last a long time. They must be well built to be this quiet. I had to replace several WINSIN fans that were very noisy. It might cost a few cents more, but it's worth it. Big Tree makes a lot of good 3D printer parts :-)

These fans work fine. I used one on the V6 hotend that I installed on my Ender 3 and the other for the circuit board fan in my case. They are not silent, but much quieter than regular ones. The only thing to note is that the terminals on the ones I received were mini JST, but as I have a JST crimp kit this wasn't an issue.

Really a shame only 2 out of 3 fans worked. TO UPDATE. Two days later one of the other fans I had already installed stopped working so now 2 out of 3 are not working. Poor quality product!

installed on my hotend for my sidewinder x1 and worked great for the first few weeks but now the first fan makes a terrible noise on startup but doesn't work still fully released. Let's see how the other 2 fans react when this one finally gives up.

These are great fans and be aware they don't use a standard sized plug (it's a bit smaller) but with a little splicing they work fine.

It's been rattling for the 3rd day. The sockets are not compatible with BigTreeTech SKR Mini sockets, so you will have to cut and solder another plug. It was quieter before the rattling started, but now it's louder than the original fans. Generally not satisfied

Same Size Fan? Yes. Does it have the same connector? Nooooo. You have to cut the end off and solder or reattach the old end or this will work like a charm
