WINSINN 40mm RGB Fan 24V, Ender 3 Fan Upgrade 24 Volt Fans LED Colorful 4010 Hydraulic Bearing, Works with Ender 3 Pro 3X CR-10S (Pack of 4Pcs)

These fans come in a 5-pack, are colorful, and I used them in my 3d printer when the original fan broke. They were a bit tricky to install, but after doing it once I have a better idea of how to do it.

These are really cool but they come with the short wires instead of the long wires to reach all the way down to your motherboard so I had to solder it in and each time I start up my printer for some reason I have to like kick start the fan so make sure you don't have a shroud over yours so you can tap it to get it going.

The media could not be loaded.  Not too long ago in a fit of boredom I ordered up a Voxelab Aquila 3D printer. I have to say it is a pretty neat little gadget, printing up toy boats, clothes hangers, drink coasters and this awesome pencil caddy on my desk. The other neat thing I learned about these 3D printers is that you can upgrade them by printing replacement parts. Almost a "Rise of the Machines" thing. Not that I think that the Voxelab will become self-aware but you don't want to take chances.So one of the updates that the Interweb was raving about was a fan shroud and new fans that would be more efficient and a bit quieter. I found files and made the shroud and then went on a hunt for some new fans. Not sure how I found the link to the WINSINN 40mm RGB Fan but it seemed pretty cool (no pun intended), quieter, they'd work in the new shroud and they also do this psychedelic color changing thing while they run. Why not add some excitement to what would normally be a mundane print?The fans arrived 4 to the box which is nice since I knew going into this I would have to splice some wires. Since I am Navy Trained (tm) that's no big deal but we all have bad days. Be sure you have the polarity down correct before installing these since (in my case anyhow) the colors didn't match my printer harness. I went out on a limb and assumed that red is hot and black is ground - Not sure what would happen if it was wired backwards but after seeing what happens when Terminators explode it's not worth the risk. Splicing, soldering and heat shrinking was a piece of cake.The fans themselves worked great. Much quieter than stock and my fingertip thermometers find that the mechanisms are being cooled properly. The disco lighting is a neat plus as well. One thing I did notice was that if if I throttled the fan speed back the lights would start flashing. (see the video) My guess is that as the voltage drops to slow down the fan the LEDs aren't getting enough juice. The fan however continues to function at the desired speed so unless you're sensitive to flashing lights it just adds to the funkiness. And we love the funk.So overall this is a solid 4. The flashing of the leds at reduced speed and lack of polarity confirmation labels cost, like, a half a point but I had to round up.

No buy keep your old ones , fans are louder then originals. False advertising. No returns or replacement when replying to them

I'm building a wearable PC using a super tiny NUC and before I improved my power efficiency I was going to use these to cool the battery, but now I'm just cooling the NUC which mostly relied on passive cooling - not anymore! It used to get incredibly warm, but with these glowing wonders it's as cool as the room I walk around in.I have to get my ear within a few inches of them to hear them at all, and they definitely blow air. One of the cables was slightly loose out of the box but I cleaned it up. They're not the best quality, but you're getting RGB fans at a unique size.I think the only real downsides are the USB cable length is a bit longer than I think is necessary, and the fact that the rotating colors can't be controlled in any way at all as they are not addressable or anything, they just constantly change. Still, totally worth it if this is what you're looking for at a tiny size.

Used these on my ender pending vid

These fans are decent. They are quiet, the lighting is good but the fans die after 3 to 4 weeks of light use on my 3d printer its not something id buy again

It seems that these reviews are for multiple products. This review is for the WINSINN 25mm RGB Fan 5V Color LED Hydraulic Bearing Brushless 2510 25x10mm - High Speed (Pack of 4Pcs).For the price, it should be obvious that these are cheap fans and expectations should be low. None the less, I purchased a 4 pack for use with Raspberry PIs. The first fan I plugged in sounded like a jet plane preparing to taxi. The second fan I tried was a little quieter, but still has a high-pitched wine. The difference between the two fans is that one vibrates at different frequencies than the other, but they both vibrate due to balancing, or lack there of. I even added rubber grommets between the fan and the case. However, the metal mounting screws still transmit the noise. So after two fans and attempts to dampen the vibration, I cannot stand the noise and will be replacing these.

i bought these fans along with the blower type , they where amazon recommended . having always bought creality before i would give these a try .anyone into 3d printing will know " the tissue test " where you see how far a fan blows a strip of tissue as a measure of the air being moved , well i can say these fans you can actually lay a strip of thin tissue on the output side of these fans as they run and it will sit there hardly if not at all moving . absolute rubbish . fans like these will lead to damage to hot ends and cause heat creep .i bought the same type but with dual bearings they seem ok thus far , time will tell .but as i said i returned these and the blower type ones i bought at the same time , i was not about to throw around £30 away on these useless fans . oh and there is no mention of the mA needed to power them very strange too high and bang goes your main printer board , too low and bang goes the fan .i will avoid this make now . very under powered .

Fitted 3 so far and 1 of them does not work, it was dead on arrival. The LED's come on but the fan does not rotate without assistance. Poor quality. Unable to return as this would mean having to take the other 2 that are already fitted out.UPDATE 9th Oct 2021: Another one has now started to fail whereby it does not always spin when power is applied unless assisted.UPDATE 18th OCT 2021: The LED;s on one of the first two fitted have started to flicker.So far, 1 was dead on arrival, one only starts intermittently and one has faulty LEDs. I won't even bother fitting the forth one as it would be a waste of time. Waste of money.

Bought to replace the hotend and motherboard fans on my Voxelab Aquila 3d printer. Absolutely transforms the printer in terms of noise. When my PSU fan is not spinning, these fans are practically silent.I have had no problems with airflow or heat creep either. All my prints are coming out perfectly, and after a PID tuning, my temperatures are holding solid.Note: The motherboard fan is just plug and play, but replacing the hotend fan requires some very simple soldering. Not hard at all, but worth pointing out to others.

The fans were easy to fit - direct replacement. Cable I would say was a bit too long, but easily rectified.The problems came in use. If you are using therse for cooling a 3d printer hotend, please look elsewhere. They dont run well, and the first fan I fitted started speeding up/slowing down - you could first hear it, then as it got worse, you could actually see the fan stuttering.Replaced it with one of the others in the pack as I thought, everyone deserves a second chance, might have been a problem with that one fan. No - it wasnt - the same for the second with worse results. Very disappointed - and now the return window is closed. If you need reliability, I wouldnt risk this - especially with a longer or overnight print that might mean you wake up to spaghetti or worse - a completely blocked hotend, with heat creep that destroyed filament guides etc - as I did.

Bought these to replace a failing fan in my oscilloscope, but of the 4 that came one made a terrible noise, another ran slowly and of the two remaining I selected the quietest but still way louder than the one I was replacing. I'm not sure if they are going to last more than a few weeks but we'll see. If you're changing a fan that's hard to get to then give these a miss.
