Reliable GdsTime GDB4020 4020 24V Blower Fan for Voron 2.4 Stealthburner Clockwork toolhead part cooling, 3D printer fan ducts, electronics airflow, and compact DIY cooling applications.
The GdsTime GDB4020 4020 24V Blower Fan is a compact 40mm x 40mm x 20mm cooling fan used for 3D printer part cooling, Voron 2.4 Stealthburner Clockwork toolheads, fan ducts, electronics airflow, and small machine cooling applications. This fan is listed on the dnb3D product page as a 24V, 0.07A brushless blower fan with dual ball bearing construction, a 27mm cable, and a 2-pin 2.54 JST-XH connector.
This fan is especially useful where directed airflow is needed through a toolhead duct or focused cooling path instead of broad open airflow. Your current dnb3D product page identifies it as a Voron 2.4 specific part used on the Stealthburner Clockwork toolhead for part cooling, with 1 piece required for that application.
The 4020 size refers to the fan’s compact 40mm x 40mm x 20mm frame. Blower-style fans are commonly used in 3D printer toolheads because they can push air through ducted cooling paths toward the printed part. This makes the GdsTime GDB4020 4020 24V Blower Fan useful for part cooling, toolhead cooling, fan ducts, compact electronics airflow, and DIY cooling projects.
This product is listed as a Voron 2.4 specific part for the Stealthburner Clockwork toolhead part cooling setup. Good part cooling can improve overhangs, bridging, small details, surface quality, and print reliability when paired with the correct filament profile, duct design, print temperature, and slicer settings.
The fan is rated for 24V operation and uses a 2-pin 2.54 JST-XH connector with a 27mm cable. Before installation, confirm your printer controller output voltage, connector orientation, wire polarity, current capability, and firmware fan settings. Incorrect wiring or voltage can damage the fan or electronics.
The GdsTime GDB4020 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 6500 RPM, airflow of 3.67 CFM, loudness of 32.5 dBA, weight of 23g, and power consumption of 1.2W. These specs make it a compact fan option for 3D printer part cooling and electronics airflow where a 40x40x20mm 24V blower is required.
Although this fan is listed for Voron 2.4 Stealthburner Clockwork part cooling, 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 40x40x20mm 24V blower fan. Always confirm fitment, airflow direction, connector style, and electrical 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 additional model reference, specifications, and manufacturer-style details, review the GdsTime cooling fan reference before installation or replacement.
Every order is hand-inspected and precision-shipped from dnb3D in Marathon, Ontario. Whether you are replacing a Voron 2.4 Stealthburner part cooling fan, building a toolhead duct, improving part cooling, or cooling compact electronics, this GdsTime GDB4020 4020 24V Blower Fan provides a practical directed-airflow option for compatible 24V systems.

Before installing the GdsTime GDB4020 4020 24V Blower Fan, confirm that your printer, toolhead, fan duct, electronics cabinet, or cooling project requires a 40mm x 40mm x 20mm 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 fan is listed as a Voron 2.4 specific part used on the Stealthburner Clockwork toolhead for part cooling. Confirm your exact Stealthburner 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 short 27mm 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.
