Good value for money but still noisy.
I love this fan except that it is noisier than my original 3d printer Wanhao fan. The set comes in a nice box which can be reused. The rottor seems like it's spinning much faster in comparison to other 24v fan I ve got, it creates more air flow as the noise comes from the air it moves and not the mechanism or bearings. Maybe a note to the manufacturer to adjust the angle of the blades. Overall good quality. Time will tell how long it lasts.

Does the job intend and working so far with 500+ hours on them
Purchased to add as auxiliary cooling on a bank of multiplexing pcbs that were prone to getting hot. These did the job and the cooling is pretty good considering the size of these units. Zero noise in my application, I did cut the plugs off and connect them all on wagos though. Reasonable quality

Cheap but noisy
Short lead is not ideal for an ender 3 but does at least have a plug on the end. I have now rigged up a connector near the hot end for quick and easy extruder fan switches, since these cheap fans give up so easy (seem to range from 1 to 6 months). Its noisy but seems to be moving the air much better than previous other fans I have tried. I can live with an increase in noise if they perform well. 5 for £10 and prime next day so good value

Good price, good quality. Also quieter than bushed ones.

Not a great low noise upgrade - fail quite soon
Having used these on a few 3d printers what initially seemed like a quality replacement, after a month of daily printing on the 3 printers i fitted them on - Ender 3's and Voxelab Aquila, they started becoming noisy and struggled to spin up to speed. Sometimes during the print you could actually hear them stutter and on a few occasions actually caused heat creep, i could tell as when i restarted the print after chopping filament and printer had cooled it would print perfect again. I'm quite experiended with 3d printers and it wasn't something like a clogged nozzle, it was purely because the fan was stuttering. Sadly these aren't great quality, a month of use (probably 10 hours a day) shouldn't mean these fail, they are cheap and i guess if you don't use them as much as me they will be ok, but for 3d printers, they a) don't last long enough and b) don't push enough air which i think its a major flaw for use in hotend cooling. I mean maybe i got a duff batch, but all 3 i have installed so far have some sort of whirring stutter and on 2 of the 3 have suffered heat creep occasionally because of the stuttering fans.

Bon produit pour ender 3 ou autre. Puissance de souffle correcte. Ils font quand même du bruit mais pour le prix c'est normal. Je recommande

One fan didn't work from the start and seller never replied to a request for a replacement.

DC-ACインバーターのFANが壊れた為、40mmが必要で取り敢えず購入しました。予備も考えて5個セットで購入です。風量は結構あります。インバーター内部も確実に冷えます。音は高音で煩いです。風量を得る為に高回転になり、煩いのかもしれません。抵抗を入れて回転数が落とせれば良いのですが? ★結論★ FANの仕事はしっかりやるが、兎に角煩い。
