Product Details
Reliable 5015 24V Blower Fan for 3D Printer Part Cooling
The 5015 24V Blower Fan is a compact 50mm x 50mm x 15mm cooling fan used for 3D printer part cooling, toolhead airflow, fan ducts, electronics airflow, and small machine cooling applications. This product is listed on the dnb3D product page as the SUNON MF5015VX-1L01C-S99, with a brushless blower-style design, MagLev magnetic suspension bearing, 27mm cable, and two-wire black/red leads with no connector.
This fan is especially useful where directed airflow is needed through a toolhead duct or focused cooling path. Your current dnb3D product page identifies it as a Rat Rig V-Core 3 specific part used on the Eva 3 toolhead for part cooling, with 1 piece required for that application. It is also listed as being used on the Voron 2.4 Stealthburner Clockwork 2.
5015 Blower Fan for Directed Cooling
The 5015 size refers to the fan’s 50mm x 50mm x 15mm body. Blower-style fans are commonly used in 3D printer toolheads because they can direct airflow through ducts toward the printed part. This makes the 5015 24V Blower Fan useful for part cooling, toolhead ducts, electronics airflow, and compact cooling paths where a standard axial fan may not provide the same directed airflow.
SUNON MagLev Magnetic Suspension Bearing
This fan uses a MagLev magnetic suspension bearing. MagLev fans are commonly valued for smooth operation, quality construction, and reliable performance in compact cooling applications. Your page describes this fan as ultra super quiet, high quality, and dust-free in design.
Rat Rig V-Core 3 and Voron 2.4 Use
This fan is listed as a Rat Rig V-Core 3 specific part used on the Eva 3 toolhead for part cooling, with one piece required. It is also listed for use on the Voron 2.4 Stealthburner Clockwork 2. Always confirm your exact printed parts, fan duct, toolhead version, wire routing, and connector requirements before replacing or installing a cooling fan.
24V Two-Wire Fan with No Connector
The fan is rated for 24V operation and includes a 27mm cable with black and red wires. Your page notes that this version has no connector, which is important for installation planning. Builders may need to crimp, solder, or terminate the fan leads to match their toolhead PCB, controller board, wiring harness, or connector system.
Airflow, Speed, Noise, and Power
The fan is listed with a speed of 6000 RPM, airflow of 4.8 CFM, loudness of 43.832 dBA, weight of 28.37g, current of 70mA with 81mA maximum, and power consumption of 1.95W. These details make it a compact part-cooling option for printer designs that call for a 5015 24V blower fan.
Useful Beyond Rat Rig and Voron Builds
Although this fan is listed for Rat Rig V-Core 3 and Voron 2.4 applications, it may also be suitable for other compatible 3D printer toolheads, fan ducts, electronics boxes, small enclosures, and low-voltage machine cooling applications that require a 50mm x 50mm x 15mm 24V blower fan. Always confirm fitment, airflow direction, electrical requirements, and wiring compatibility before installation.

Installation & Care
Installation, Handling & Care
Confirm Fan Size and Voltage
Before installing the 5015 24V Blower Fan, confirm that your printer, toolhead, fan duct, electronics cabinet, or cooling project requires a 50mm x 50mm x 15mm 24V blower fan. Do not connect a 24V fan to the wrong voltage output or an incompatible controller circuit.
Plan for Bare Wire Installation
This fan is listed with a 27mm cable, black and red wire leads, and no connector. Before installation, confirm how the fan will connect to your printer or toolhead PCB. Use proper crimping, soldering, heat shrink, strain relief, or connector hardware for your build.
Check Wire Polarity
Confirm positive and negative wiring before powering the fan. Incorrect polarity or wiring to the wrong voltage can prevent operation or damage the fan or electronics.
Confirm Rat Rig or Voron Fitment
This fan is listed for Rat Rig V-Core 3 Eva 3 toolhead part cooling and Voron 2.4 Stealthburner Clockwork 2 use. Confirm your exact toolhead version, printed duct, fan mount, screw clearance, connector routing, and airflow direction before installation.
Confirm Blower Outlet and Duct Fitment
Blower fans use a directed airflow outlet, so orientation matters. Confirm that the fan outlet matches your printed duct, toolhead mount, electronics enclosure, or airflow path before tightening the fan in place.
Mount Without Distorting the Housing
Use appropriate mounting screws and avoid over-tightening. Small fan housings can warp if compressed too hard, which may cause impeller rubbing, vibration, extra noise, reduced airflow, or shortened fan life.
Keep Blades and Air Path Clear
Make sure wires, filament strands, printed duct edges, screws, and debris cannot contact the blower impeller. After installation, spin the fan gently by hand and check that the impeller rotates freely before powering the printer or electronics system.
Route Wiring Away from Heat and Motion
Route the cable away from hotends, heater blocks, belts, pulleys, moving toolhead parts, fan blades, sharp edges, and hot electronics. Use strain relief where needed so the cable and any added connector are not pulled during operation.
Clean Dust and Filament Debris Regularly
Blower fans can collect filament dust, plastic strands, and shop debris. Inspect the fan during routine maintenance and clean carefully with power disconnected. Avoid pushing debris into the bearing or damaging the impeller.
Test Before Long Prints or Extended Use
After installation, test fan operation through the printer interface, controller output, or electronics setup. Confirm that the fan starts reliably, reaches expected speed, moves air in the correct direction, and does not make rubbing or grinding noises.
