Frequently Asked Questions
Q: What voltage should I choose for my Creality Ender 3 or CR10 3D printer?
A: Most Creality Ender 3 and CR10 printers use a 24V power supply, so the 24V version is typically the correct choice for direct board or PSU connection. However, if your printer has a dedicated 12V rail or you are powering the fan from a separate supply, select accordingly. Always confirm your printer's fan voltage before ordering.
Q: Is this fan compatible with other 3D printers besides Ender 3 and CR10?
A: Yes! The standard 40x40x20mm size and 2.54mm 2-pin connector are widely used across many 3D printer brands and models, as well as in small computer builds, electronics enclosures, and DIY electronics projects. As long as your application requires a 40mm DC fan at 5V, 12V, or 24V, this fan should be compatible.
Q: How loud is this cooling fan during operation?
A: The HUXUAN DC4020 mini cooling fan is designed for efficient, low-noise airflow suitable for desktop and workshop environments. While exact decibel ratings vary by voltage and load, the compact blade design prioritizes steady airflow while keeping operational noise to a minimum.
Q: What is included in the package?
A: Each order includes 1 x 40mm DC cooling fan with a 30cm pre-attached cable and a 2.54mm 2-pin connector. No additional accessories or mounting hardware are included.
