Perfect fit! Love the ball bearings!
Exactly the size/voltage that I needed to replace a worn out fan. The old fan always made bad noise for first minute or two. I love these new fans with ball bearings!!! No nasty startup noises! The just go!

Quiet and Powerful… a great upgrade for your 3D printer
Had to replace the extruder cooling fan on my Anet A6, it was starting to get SUPER LOUD and it sounded like that it was only a matter of time before it failed completely. This fan is pretty much a drop in replacement, with one caveat: at least on my Anet A6, that the JST connector was wired incorrectly (It was wired backward.) Also the cable wasn’t long enough to reach the connector on the motherboard, so I had to lengthen it; I reversed the wiring of the connector at the same time I did that. Other than that this fan has been performing flawlessly, and I run my Anet A6 pretty hard (not quite 24/7, but darn near close.) These Winsinn fans are just as powerful as the stock Anet fan (maybe even more powerful?) and is WAY quieter. Would definitely recommend.

Fantastic replacement fans for Creality printers, but QC could be better
24 hours into me using the Ender 3 my father bought me as a birthday gift, the hotend fan failed and I decided to replace it with a fan from this kit after watching BV3D’s video on the subject. I’m glad I did because even though these fans aren’t the quietest replacements out there, they are still pretty quiet and supply more than enough airflow for the hotend. Even swapped out the mobo fan for one. Been running them for almost two weeks now without any problems.However, I have to knock off a star because QC could be better. One of the fans arrived with a broken blade and wobbles when it spins up. The other four arrived in perfect shape, so overall, $20 for four working fans of this quality is still a fantastic deal.

Bolt On Replacement for Powerspec I3 + Printer.
The extruder fan on my Powerspec I3 + Printer (Wanhao I3+ clone sold by Microcenter) had a broken power lead after I cleared a plugged nozzle, so I looked for a replacement fan. When I saw these, I was impressed by the good reviews, so I bought a package of five fans. These fans fit perfectly on my Powerspec I3 + Printer and the one I installed spun up immediately and started doing what fans do. The only down side is the wire length is longer than my printer needed, but it tucked up under the connector cover with no problems. Maybe later I will shorten the wires, but I needed to get the printer up and running right away, so I didn’t break out the soldering iron.The fan itself makes a good amount of noise, but it isn’t overly obnoxious. If these were quieter, I would have given five stars.I had to buy five fans when I only needed one, but I guess that makes it possible to get the fans for a decent price. I would have willingly paid up to $10 for a single fan. Evidently it doesn’t make financial sense for Amazon to sell these individually. Because I had to buy more fans than I needed, I gave a four star rating for value.I would definitely buy this product again, but I probably have a lifetime supply of them now!

Big improvement over cheaper fan
I replaced the fan on a power supply that I use for charging batteries. I wasn’t sure if it would be worth the effort, but it definitely was, the power supply is nearly silent now compared to what it was before with a bushing fan.

Noisy but very good
* Dual Ball Bearing* High Speed* 5vOkay so these are very noisy at 5v, less in 3.3v but the air flow is amazing. I bought the 5010 too, the bigger ones a few weeks back, and I feel the 4010s are louder.Anyways these are meant to be loud since they are dual ball bearing and the high speed model. So I connect it with 3.3v in the ice tower cooler in my raspberry pi.It cools much much than the default colorful fan that come with the ice tower, which I believe is a sleeve bearing. And sleeve bearings die soon and suddenly.I use a script to turn fan on/off based on temperature to prolong the fans life. But I’ll update this review when the fan dies…

Perfect fit on Ender 3 Pro!
Had a blade snap on my Ender 3 Pro’s hotend fan and these were a perfect fit for replacement. I bought the ‘High Speed’ version and they run great. Definitely moves more air than the stock fan did and it seems a little quieter as well (hard to tell because the power supply fan is so loud). They fit perfectly in the stock casing without having to grind/drill/modify in any way.Fans come with decent cable length and a nice JST-XH connector that I ended up cutting off. Spliced on some 2-pin DuPont connectors to wire it up. I’ve read some reviews that said these were wired backwards, but this was not a problem with the ones I received.One thing worth noting is that you can buy these direct from WINSINN’s website for about a dollar less (for the 5-pack) and with 1-meter length cables. The only reason I didn’t buy that instead (could have ran the wiring all the way to the mainboard without having a splice in the middle) is that WINSINN’s site said that because of Chinese Lunar New Year I’d have to wait at least 3 weeks or more to get them shipped. It wasn’t clear if this affected parts stocked at the US warehouse, but I didn’t want to chance having my printer down for that long.

Replacement fan motors for my Dry Guy Turbo boot dryer
Several years ago I bought a Dry Guy Turbo boot dryer for my work boots. I dry my boots out every night, and over time the original sleeve bearing motors in the drying fans in the Turbo boot dryers have worn out. I saw these fan motors that are the same physical size and that have dual ball bearings in them, so I bought them to try them out in my boot dryers. They are advertised as having a 50,000 hour lifetime, so I bought them to try them out. They are a direct swap for the original motors, and I will put a small 2.5 sized connector on the new fan motor power wires so that I can switch motors quickly and easily should they fail. These new motors with the dual ball bearings should last me for many years and will keep my work boots nice and dry. At 8 hours of drying time per night, these new motors should last me for 17 years if they are what they say they are! At 81 years of age, they should last me the rest of my life….. Stay tuned on that issue….

I needed the two wire model with bearings, so returned them. I have the two wire model with the liquid bearings but wanted ball bearings instead as the liquid ones only lasted a year before becoming very noisy so I could not rint at night when a long print was running. Printing 3 or four prints a month @ 12 to 20 hours.

Cambie a esta marca de ventilador porque pensé que se disminuiría el ruido. Y en principio así fue. Al paso de 2 días hacen mucho más ruido de lo que hacía el ventilador original con muchos más días de uso.
