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

Worked great foe a new cooling fan on my 3D printer

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)

Bought these as part of a hot-end upgrade for my Ender 3. Fans are quieter than stock, but not super silent. They have a decent amount of whine at lower speeds.One big thing to note is the connector polarity. I did not double check when installing the for my initial test, and neither fan would spin up. After a bit of troubleshooting, I discovered the plug had the positive and negative wires switched. Popped them out of the plug and swapped them over and all is good!Haven't fully installed them yet, so no comment on durability yet

This fan is a good replacement for my Vicks humidifier. The original fan stopped working. This fits perfectly, wiring is a good length, two pin plug fits. The speed seems close to the original even though the amps are slightly different from the original. It is also quiet, close to the original or maybe quieter. With the 2 pack I will have a backup. The original only lasted a few years using it during the winter.

Works good and moves air but one fan came dead on arrival and having to swap polarity to make it work with the printer is pretty whack. It'll get the job done but maybe see what else is out there. So far not happy with the QC and the need to reverse things to make it work out of the box.

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.

They work as intended. No complaints.

I used this to replace a fan that was failing in my humidifier. It works and puts it considerably more air than the fan it replaced despite the same voltage and current rating but it also emits a audible whine while in operation the old fan did not. I suspect it is not louder than the dB they spec but still makes it less suitable for bedrooms or places you need quiet.

After reading a post on reddit praising them, I bought these for my 3D printer and I had high expectations of getting lower PWM whine. But these were definitelly worse than the ones I own which are 4 times cheaper than these... So, I returned them and I won't recommend buying these.

Used these to upgrade my 3db printer from a single radial 4010 to two of these. It's a huge increase in cooling ability but also huge increase in noise level, especially when driven at 100%. Even running at 50%is slightly louder, but bearable, compared to stock 4010 fan.

Usable but definitely poor quality. I'm considering ordering from a reputable 3d printing store and tossing these.

I'm really disappointed in these fans. They're way louder than the stock fan on my Ender 3 Pro. They make an awful electronic whining noise when run at anything less than 100% power, and when running at 100% they are super loud. They are also not well balanced - one of them vibrates so much that it makes the entire hotend vibrate and ruins the surface quality of my prints. The other one vibrates a lot too but not quite as bad. These fans are going straight into the garbage. Don't waste your money.

needed 2 fans, ordered this kit, but can only use one, the pad on one fan was not even connected.
