ANVISION 2-Pack 40mm x 10mm 4010 Dual Ball Bearing DC 12V Brushless Cooling Fan, YDM4010B12

Good value, quiet fans.This is the second replacement fan I've had to install on one of my Creality Ender 3 V2. First replacement from another supplier lasted 3 weeks, was noisy from the beginning, got worse and finally seized.These ones so far are quieter from the first time of turning them on, and so far no issues at all. Providing they last more than a couple of months then I'll be happy.

I'm using these on a Monoprice Maker Select Plus. They're audible, I mean they sound like a harrier taking off. Maybe it might be worth a step-down converter, or just reducing fan speeds. But they do what they're supposed to--they move air.

Why did you choose this product over others?:Size, it fits between the fly screen and the outer grill on caravan fridge exhaust. Used to boost flow.

it works as a replacement for a cooling fan for my printers board. sound wise very simular to the old one before it failed.

Those have a slightly high pitch, but are less noisy than the original Flashforge ones.I did try to replace the ones in the extruders (Creator 3) but the very quiet models won't give enough airflow resulting in poor cooling off the hotend, which means a nasty clog.Had never happened with those, so it's good for now

Sorry, but I'm rather disappointed with the noise level which is practically identical to the original fans that came with my Ender 3 Pro. I measure 55db with the decibel meter on my iPhone around half a metre from the machine, which is the same reading as before I changed the extruder fan and the motherboard fan. Other than that, the fans work fine. All the hassle of changing the fans for absolutely no gain.

Good little fans. Bought to increase the air flow inside my pc, have worked very well. Very impressed, would recommend.

Sadly I had a faulty set one the wire fell off the fan connection as soon as it was fitted.
