Compatible Machines:
- Universal – This works with any 24V printer when you use a hotend mount that supports a 5015 Layer Fan.
Installation Notes:
- Be sure to check the polarity on the wires you are connecting our fans to. Typically red is positive and black/blue is negative but some of the Chinese printers do not adhere to these standards.
- There is no list of what machines use what as it can vary from model to model and we have even seen differences in wiring colors used in the same printer models.
- Our fans use red for positive and black(or blue) for negative. You can verify polarity with a cheap $10 multimeter from Amazon or you local hardware store.
- If fans are shorted out/killed due to improper wiring this is NOT covered under warranty.

DIY Part Fitment/Installation/Wiring
This is a universal DIY 3D printer part. That means it will work on almost any 3D printer, but you must know what you are doing.
Our technical support does not cover selecting/designing/assisting in firmware setup and/or 3d models to install this part on your printer. If purchased as part of a kit from TH3D for a particular printer, then it will be covered under the kit when using our firmware package.
Electrical replacement parts usually will require you to splice wires into your existing ones for the part you are replacing (soldering and heat shrinking wire splices is recommended for proper connection).
Some of our universal electrical parts come with bare wire ends or plugs on them. These ends may or may not directly plug into your 3D printer. If they do not, you will need to splice the wires into the existing ones on your 3D printer.

The TH3D team only selects the best parts. This is why these fans are selected as well. unlike the Noctua fan pushing much lower air flow this 5015 blower is a powerhouse. There is some whine initially but partnered with the fan fix from the TH3D unified firmware that is gone instantly.
Once again a great product for any system.

So you need a fan? They don’t last forever so buy an extra. This is an exact reply just double check the voltage 12/24

This fan is the fan I adapted for my Artiller3D sidewinder. The stock fan is like a fart in the wind, and this fan is like a hurricane. I can’t believe how hard this fan blows. Also the picture doesn’t look like the fan I got. The one I got looks like a micro DC RC motor with a fan blade on it. Get this fan.

I was previously using 2 4010 fans in a hero me duct. Because I am adding the EZabl I decided to go with a single 5015 fan to clear up room on the left side of the nozzle. I can tell you this 5015 fan moves more air than dual 4010’s. I am totally impressed with this fan. On my Ender 5 it will not run with anything less than 100% speed. I am installing an EZboard in the next couple of days so I will take care of that problem at that time. Buy this fan. You will be glad you did.

Works great with the petsfang fan mount on the Ender 3 with the tough hotend. Quiet and high cfm. Great quality

These TH3D fans are definitely an upgrade from the ones I bought on Amazon. Significant quality difference. I now have dual 5015 on the hotend, can make the longest ridiculous bridges and over hangs. Accidentally got shipped a 12v and 24v, instead of dual 24v, but customer support rectified the issue and sent a replacement out literally the next day. Couldn’t be happier going through TH3D! Thanks.

They blow a lot of air and still work at very low fan speeds. They seemed kind of weak at first, but I guess there was a break-in period since they blow a lot more air now.

This is a nice upgrade for my Sunlu S8 with a Red Squirrel shroud. Tons of airflow!
