WINSINN 40mm Blower Fan 24V, Ender 3 Fan Upgrade 24 Volt Fans Blower 4010 Dual Ball Bearing, Works with Ender 3 Pro 3X CR-10S (Pack of 5Pcs)

I purchased the quiet version of this fan in the 24v version for my Ender 5. I would estimate they put out about 1/4 to 1/3 amount of air as compared to the originals. I have a dual fan setup so I can compare side by side. These quiet fans have less cup to the blades compared to the originals. I'm sure that is what makes them more quiet but also move less air. The regular (high speed) version of this fan may work just as well as the original but I don't know that for sure. I can tell by the pictures that the regular fan blades look more like the stock fans. If you are wanting to replace your fans and need similar air flow, these quiet version fans are probably not for you. I wound up not using them for my printer.

Working better then stock fans

depending on your use case this might be the fan for you. I used it as a replacement for the stock fan on my ender 3 v2 (3d printer), and it is inadequate for this application, and doesn't move enough air to cool the print.

Great upgrade for stock fans.

I bought these to replace my Crealty Ender 3 v2 stock fan because it broke after 2 months of use...it fits great and works even better I totally recomend itI didn't gave it the 5 Stars because the wiring is different color but you can guess which one is which

These fans are small but the push a decent air volume when running at a full 5V. I found through testing that they can be run at higher voltage, but have only tested up to 9 volts and they really blow some air when running at that voltage level.I cannot attest to longevity of the fans as I have only used them in 2 projects so far and both are still working great but they have only been run for a few hours each.Overall I would recommend these as a cheap replacement for a 3D printer part cooling fan, but time will tell how often they will need replacement.

Great fans, quiet. The only problem is the length of the connecting wires. I had to cut and splice the old wire to the new fan. Otherwise works wonderfully.

Seems like there are at least two kinds of WINSINN 40mm fan - with thin and thick mounting pieces. Clear note in this regard should be added to the product description by Manufacturer. That's why only three stars.From all other points of view the fan is perfect, though a bit noisy - as all ball bearing fans are - and whining while used on PWM.

I got these for my ender 3 when my stock fan died. The supplied wiring is not long enough to reach the motherboard so i had to join them to a longer piece of wire via a junction.All done i thought..and then i turned the printer on..good god..sounds like a jet engine when they (eventually) kick in. Not sure whether they are unbalanced or what but they have a high pitched whine that makes it impossible to stay in the same room when they are in action. Will be searching for alternate fans ASAPEdit: i have gone through 3 of the fans already! I am beginning to suspect that these ARE NOT the 24v fans as advertised and may be a breach of trading standards! Do not buy this product!

these fans are not only less powerful than my old broken fans but smaller . the center part is 3 mm smaller , so that means less air getting pushed out . again with this brand no mA marked on them so no idea if i`m going to damage my printer or not . a genuine ender fan is marked 0.01mAi returned them along with the 4010 ones i bought along side these. i will avoid this brand from now on .

... but just. They randomly start making satanic noises, but they keep blowing air. I glued one of these onto a QLogic 10G NIC. No ragerts.

Nice quiet reliable fans, they are my got to fans from now on.

Bit noisy but Bearable
