Frequently Asked Questions

Q: What voltage should I order — 12V or 24V for my 3D printer?

A: This depends on your printer's power supply. Most standard Reprap and Prusa i3 builds use either 12V or 24V systems. Check your printer's mainboard or power supply label for the correct voltage. The default shipped voltage is 12V — please specify 24V in your order notes if needed.

Q: Is the Mellow 5015 fan compatible with Prusa i3 and Reprap printers?

A: Yes! The 5015 turbo blower fan is specifically designed for use with Reprap, Prusa i3, and many other popular FDM 3D printer platforms. Its 50×50×15mm form factor and 54.26mm mounting pitch fit most standard fan mounts and part-cooling ducts.

Q: How long will these 5015 blower fans last?

A: The Mellow 5015 fans are rated for approximately 28,000 hours of operation, thanks to their oil-bearing (sleeve bearing) construction. This makes them a durable, long-lasting upgrade for continuous-use 3D printing environments.

Q: How noisy are these fans during operation?

A: The 5015 blower fans operate at 29 dBA on 12V and 30 dBA on 24V — relatively quiet for a turbo-style blower, making them suitable for home workshops and office environments where noise is a consideration.
