It outputs a 25 kHz PWM signal (configurable), which is compatible with most modern 4-wire PWM computer and industrial cooling fans.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I power this fan controller with a regular USB charger or power bank?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The module powers via a USB Type-C port at 5V, supporting up to 8W output in this mode — making it compatible with most standard smartphone chargers and power banks for convenient, plug-and-play use. For higher-current applications, connect 12V 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 your desired low (L) and high (H) temperature thresholds using the rotary encoder. When the measured temperature rises to the L threshold, the PWM duty cycle begins increasing linearly from 10%. By the time the H threshold is reached, the fan runs at full 100% speed. This smooth, proportional response avoids sudden speed jumps and keeps your equipment optimally cooled.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I switch between temperature and RPM on the display?\u003c\/h4\u003e\n\u003cp\u003eA: Simply press the display button briefly (short press) to toggle between the real-time temperature reading and the current fan RPM. This lets you monitor both key parameters without any additional equipment.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What types of fans are compatible with this PWM fan speed controller?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This controller is designed for standard 4-wire PWM fans, including those used in PC cases, server racks, motors, greenhouses, and aquarium setups.
