Frequently Asked Questions
Q: What input voltage does the fan temperature control board support?
A: The board accepts a constant DC input voltage of 12V to 32V, making it compatible with a wide range of power supplies commonly used in DIY electronics and custom builds.
Q: How does the automatic temperature control work?
A: The included thermal-sensitive probe monitors ambient or component temperature. Once the probe detects a temperature of 35°C or above, the board activates the fan and adjusts its speed proportionally as the temperature changes — automatically, with no manual input needed.
Q: Can I connect more than one fan to this control board?
A: The board is designed to control one DC fan (12V, ≤ 0.4A) at a time. If you need to run multiple fans, it is recommended to use one temperature control module per fan for optimal performance and motor protection.
Q: Do I need soldering skills to install this board?
A: No soldering is required. The board features a solder-free design with simple terminal wiring, making it accessible for beginners and seasoned hobbyists alike.
