It supports both 5V and 12V fan configurations depending on the power source used.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need a special power supply to use this controller?\u003c\/h4\u003e\n\u003cp\u003eA: No special power supply is needed. The module is powered via a standard Type-C interface — any USB-C phone charger or power bank can supply power. For 12V operation, you can connect via the onboard terminal.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the automatic temperature-based speed control work?\u003c\/h4\u003e\n\u003cp\u003eA: You set a low (L) and high (H) temperature threshold using the rotary encoder. When the ambient temperature — measured by the included NTC probe — rises above the low threshold, the controller begins linearly increasing the PWM duty cycle (fan speed) from 10% up to 100% as the temperature approaches the high threshold. This ensures smooth, quiet, and efficient cooling automation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I monitor fan speed and temperature at the same time?\u003c\/h4\u003e\n\u003cp\u003eA: The HD digital display shows either real-time temperature or current fan RPM. You can toggle between these two views with a single button press, giving you full visibility of your system's operating status at a glance.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What fans are compatible with this PWM fan speed controller?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This module is compatible with standard 4-wire (4-pin) PWM fans commonly used in PC cases, servers, greenhouses, and aquarium setups.
