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

I bought the set of 2 24v blower fans for use with an Ender 3 (3d printer) dual fan part cooler plenum (see the pic). The set installed without issue and worked properly, with leads soldered to the 24v part cooler supply circuit . Unfortunately, after a few hours one of the fans did not start when I initiated a new print. Later on it did run, although somewhat erratically, if at full speed. It would not spin when any slower speeds were called for by the printer. The vendor was very responsive when contacted & immediately provided a replacement. The replacement works well at all speed settings as does the other of the original two. Noise is not excessive even with both fans at full speed. I have not noticed any high pitched noise when run at slower speeds.

I did a 5015 dual fan conversion on an FLSUN delta printer. The stock fans didn't push much air, and the stock air nozzles don't point correctly for a volcano nozzle's height. These were easy enough to wire up. I cut the connectors off and wired up the connectors from the original fans.These fans both spin properly at full speed and varying speeds throughout the RPM range. They push a good amount of air, and are not crazy loud. Can't ask for much more than that.

Only dislike I have is just like a lot of people has pointed out the wires are very thin and so very hard to actually get soldered on a very small pad but would it hurt to put a bit of hot glue over the wire and soldered joints so that the wires don't have a chance to come undone and kill someone's printer or other expensive electronic gear? But other than that the fans are great they put out a whole lot of air compared to the stock 4010 parts fan that my Ender 3 V3 SE comes with. Once I printed a new Air duct for my print it just went fine. Just one note is get some JTS connectors that are 1.25mm in size so that you can just wire them right into the main printer power without having to play Dr. Jekyll on your stock fans cables to get a pig tall that will work. As for noise yes it can be heard but it way less then the stock 4010 fan was doing for me. Will worth getting a few them just do yourself a favor and when you get them take and lift up the sticker where the wires run under it and put a bit of hot glue on the pads and then that will save you a lot or problems later on also makes the fan last longer.

I used these fans for my Ender 3, 3D printer. I'm currently using the Hero Me Gen 7 parts cooling system and it needed 5015 fans. These work very well and are not too loud.

Use: for part fan on a 3d printerNoise: Bearing is very quiet, the only thing I can hear is the air being blown out of the nozzleMy issue: after about a month of use, the solder connection from the wires to the board fell off rendering one of the 2 fans useless. I tried to take it apart to fix the connection, but ended up breaking the housing trying to remove the fan blades. Hopefully I have better luck with the second fan.

I ordered a 2 pack of 24V 5015 fans from a different brand on Amazon and both immediately began smoking upon connecting to my 24V fan plug that my 24V 4010 Fan (same current) was running smoothly on. Talk about frustration. 2 in a row. I used a my 24V powersupply to also test the fans getting the same results (must have been 12v fans relabled 24v)These SoundOriginal's I received both fired right up out of the box on testing with my power supply and then on my 3d printer. Impressed by the noise level- at 100% it sounds like a quiet mini-laptop fan. No whine at all, just the sound of whoosing air and it puts out some surprisingly good air flow. I don't have any other brands or experience with 5015 so this review is limited to just my first hand experience. I don't know if they should be putting out more air or not; but it was certainly quite a bit more than my stock 4010. I would recommend this brand if you're looking for 5015 fan replacements on a 3d printer.

Just what I said, some other reviewers seem to have had a similar experience.They are loud as well, I am looking into the WinSinn instead as those are apparently ball-bearing fans.

Great little fans! I have them both installed on my 3d printer instead of the stock fan, and it cools the parts and nozzle much much better

I used these on my 3d printer hotend, on my petsfang duct. They work fairly well but are not the quietest out there. It is also not loud compared to other fans.

UPDATE:i was able to look into the fan and there was a debris on the fins that i waa able to remove.so far working well and acceptable noise level.using this as part cooling and hotend fan for my ender 3 s1 pro.1 of the fans is noisy and has a low grinding hum when it runs.the other one is performing ok without noise.a bit disappiinting as the air push is quite strong.

I'm using for part cooling on and Ender 3 V2. A change of extruder necessitated a change of duct and the quiet Sunon 4020 radial fan I was using didn't seem to have enough oomph with the new, narrower duct. This fan is at least as quiet as, if not quieter, than the Sunon. It blows much, much stronger on full speed and has a more linear variation in speed from setting 1 all the way to 255 (the Sunon wouldn't start spinning until ~85) The polarity of the DuPont connector was the wrong way round for the mainboard header, which caused a few moments of confusion when I was testing the fan, but wasn't an issue as I had to cut and rejoin the wires anyway.

It is relatively quiet and pushes a lot more air than a traditional fan. I’m using it on my 3D printer, and it has improved my print quality tremendously.

These are decent fans for the price. They are not ball bearing fans so they are louder and will wear out sooner or later. But they do push good air. I have had them running on my 3D printer for about 3 weeks and one is starting to howl already. The brass bushing is starting to wear out. But for the price I didn't expect much else.
