24V DC Brushless Blower Cooling Fan 50x50x15mm,for 3D Printer Humidifier Aromatherapy and Other Small Appliances Series Repair Replacement (24v Dual Ball Bearing 2pack)

This fan was an easy install. It is quiet when running and seems to have as strong of an airflow as the original. My only ding is that you have to buy two.

Ender 3 V2's small 4010 part cooling blower fan was making some horrible noises during preheat so I used one of these fans to upgrade the system. Printed a new fan duct system (Red Squirrel Remix) and it works quite well. I typically run the part cooling fan at only 50% now so it's quieter than the old fan and I have extra part cooling capacity when needed. This is the size fan they should have used on the stock system.

Ive bought two packs of these fans. One fan had the solder (on the fan board) disconnected on arrival, but after soldering it back together it's ran fine for a few months. I have sunon maglev fans too and I still use this over them for my 3d printers. They are quite a bit louder than the maglevs but they put out noticeably more air. I think these are better than Winsinn and on par with GDSTime personally.

These things are not expensive, and they work great. Put them on my Anycubic Kobra Plus and they work great. I would love for them to be quiet, but they are not as loud as server fans.

Guys, if you value your sanity do yourselves a favor and go to your goodwill or Walmart, pick up a small humidifier and use the 5020 or 5015 fan in that instead. They WILL be higher quality than anything I’ve found on Amazon. I knew the fans on this page would be loud, they’re blowers, but these things scream bloody murder. It’s not just a loud whirring- it’s frequent clicking and vibration from imbalance, I presume from either the dented walls on the bearings or the spring that keeps tension on the spinning turbine catching and releasing. I could hear these running a floor below me with the door closed. Avoid these and save yourself the money and sanity.

The media could not be loaded. I wanted to upgrade the part cooling fan on my Artillery Sidewinder X1 and this fan did the trick. It already came with the correct connector on the end and it fit perfectly into the upgraded fan shroud I printed. The sound is very reasonable running at full speed and honestly, it's quieter than I expected. When running at less than 100% it's not very noticeable and there is no discernable whine like on some cheaper fans. I'm glad it was a 2-pack so I have a spare just in case.Video is the fan off and then going to 100%

I picked up some really quiet 5015 fans from another manufacture. They were used in a dual blower setup for part cooling on a 3d printer. One of these fans moves more air than the dual blower setup...by a significant amount. I am very willing to accept a medium sound level for fantastic part cooling. I happily print at +100 mm/s and don't have any cooling related issues because of these fans! I use the HeroMe Gen 5 fan ducts.(I'm about to buy 4 more of these for 2 dual extruder printers I'm building)

I run one of these at 50% speed and its quieter than the stock fan was on my SV06 Plus. A lot of people complaining about "whine" is because their machine is using PWM to control the fan. Google PWM whine and you'll find its very common. My machine drops voltage to around 8v for around 20% or goes to 24v at 100% so there's no PWM whine. I think if you understand that this is a blower, and it moves a lot of air, and air movement = noise you'll be pleased.
