Sunon 5015 Blower Fan 24V DC Centrifugal Cooling – Voron 3D Printer
Sunon 5015 Blower Fan 24V DC Centrifugal Cooling – Voron 3D Printer
Sunon 5015 24V DC Centrifugal Blower Fan – Double Bearing Turbo Cooling for 3D Printers
Upgrade your 3D printer's cooling system with the Sunon 5015 Blower Fan — a high-performance centrifugal (radial) fan engineered for precision component cooling. Compatible with popular builds including Voron Stealthburner, this 50×50×15mm turbo fan delivers superior static pressure and airflow compared to standard axial fans, making it the go-to choice for directing cooled air precisely through fan ducts and part cooling shrouds.
Unlike axial fans that scatter airflow in all directions, this radial blower channels air with focused, high-pressure output — keeping your printed parts cooling evenly at high speeds without excess noise or bulk. Each unit is individually balanced for ultra-quiet, vibration-free operation throughout its lifespan.
Made in Mainland China.

Why Choose a Centrifugal Blower Over an Axial Fan?
Centrifugal (radial) blower fans generate significantly higher air pressure than traditional axial fans. This means the airflow is effectively directed through narrow fan ducts and part-cooling shrouds — exactly where your 3D print needs it most. The result is better layer adhesion control, sharper overhangs, and cleaner bridging on complex prints.

Frequently Asked Questions
Q: Is this 5015 blower fan compatible with Voron Stealthburner and other Voron builds?
A: Yes! The Sunon 5015 24V DC centrifugal blower fan is specifically designed and widely used in Voron Stealthburner toolhead builds. Its standard 50×50×15mm 5015 form factor also fits a wide range of other 3D printer toolheads that use 5015 blower mounts.
Q: What does the third pin on the connector do?
A: The third pin is a tachometer (RPM signal) wire that allows your printer's control board to read the fan's real-time speed. Note that while the pin is present on the fan housing, the signal wire may not be connected/installed out of the box — the two active power pins are functional and ready to use.
Q: How does this centrifugal blower fan compare to a standard axial fan for 3D printing?
A: Centrifugal blower fans like this 5015 model generate far higher static pressure than axial fans, allowing airflow to be pushed efficiently through narrow fan ducts and directed precisely at the printed part. Axial fans disperse air radially and are better suited to open-area cooling, while blower fans excel at focused, duct-channelled cooling critical for quality 3D prints.
Q: Is this fan individually balanced, and will it run quietly?
A: Yes. Each Sunon 5015 fan is individually balanced at the factory to minimize vibration and noise. At rated voltage it operates at approximately 43.8 dB(A) — reasonably quiet for a high-static-pressure 6,000 RPM blower, especially when compared to louder aftermarket alternatives.
