Reliable 5015 24V Blower Fan for Rat Rig V-Core 3 Eva 3 toolhead part cooling, Voron 2.4 Stealthburner cooling, 3D printer fan ducts, electronics airflow, and compact DIY cooling applications.
$10.95
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 Caizhu 5015DC24V, with 24V operation, 0.1A current, brushless blower-style design, dual ball bearing construction, a 27mm cable, a 2-pin 2.54 JST-XH connector, and an included 1500mm extension cable.
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.
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, enclosure cooling, and compact cooling paths where a standard axial fan may not provide the same directed airflow.
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. Always confirm your exact printed parts, fan duct, toolhead version, connector requirements, wiring length, and airflow direction before replacing or installing a cooling fan.
The fan is rated for 24V operation and includes a 27mm cable with a 2-pin 2.54 JST-XH connector. Your page also notes that it includes a 1500mm extension cable, which can make installation easier in printer builds where the fan wiring needs to route through a toolhead harness, cable chain, or electronics bay. Before installation, confirm polarity, connector orientation, voltage, and controller compatibility.
The Caizhu 5015DC24V is listed with dual ball bearing construction. Ball bearing fans are commonly preferred for toolhead and machine applications because they can support continuous use and varied mounting orientations better than many basic sleeve bearing fans. This is helpful for moving 3D printer toolheads and enclosed printer environments.
This fan is listed with a speed of 5500 RPM, airflow of 14.1 CFM, loudness of 32 dBA, current draw of 0.1A, and air pressure of 0.19. These specs make it a practical compact part-cooling option for printer designs that call for a 5015 24V blower fan.
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.
For related components, browse the 3D Printer Parts category or the Electronics category. This blower fan can be paired with fan ducts, toolhead PCBs, hotends, extruders, connectors, wiring, silicone socks, and other cooling hardware from dnb3D.
For printer build reference and part compatibility context, review the Rat Rig V-Core 3 GitHub documentation or the Voron 2.4 documentation for your specific toolhead and cooling configuration.
Every order is hand-inspected and precision-shipped from dnb3D in Marathon, Ontario. Whether you are replacing a Rat Rig V-Core 3 Eva 3 part cooling fan, maintaining a Voron 2.4 Stealthburner toolhead, building a fan duct, or cooling compact electronics, this 5015 24V Blower Fan provides a practical directed-airflow option for compatible 24V systems.
The 5015 24V Blower Fan is a compact Caizhu 5015DC24V cooling fan for compatible Rat Rig V-Core 3 Eva 3 part cooling, Voron 2.4 Stealthburner cooling, 3D printer fan ducts, electronics airflow, and compact machine cooling applications.

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.
This fan is listed with a 2-pin 2.54 JST-XH connector and 27mm cable. Confirm connector fit, wire polarity, and controller-board pinout before powering the fan. Reversed polarity or incorrect wiring can prevent operation or damage electronics.
This product includes a 1500mm extension cable. Route the extension cable cleanly through the frame, cable chain, wire loom, or electronics bay. Avoid sharp bends, pinch points, moving belts, hotend heat, fan blades, and exposed terminals.
This fan is listed for Rat Rig V-Core 3 Eva 3 toolhead part cooling and Voron 2.4 Stealthburner use. Confirm your exact toolhead version, printed duct, fan mount, screw clearance, connector routing, and airflow direction before installation.
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.
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.
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 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 connector are not pulled during operation.
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.
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.
