DC12V 1A Automatic Temperature Controlled Fan Speed Governor with Sensor, Intelligent PC CPU Case Fan Speed Controller, Compatible with 2Wire 3Wire 4Wire Cooling Fans

This DC12V automatic fan speed controller comes with external temperature sensor to realize intelligent fan speed regulation. It dynamically increases fan speed when temperature rises to enhance heat dissipation, and reduces rotation speed under lowtemperature condition to lower operating noise. Rated 1A output current supports most conventional case and CPU cooling fans. It is compatible with 2wire, 3wire and 4wire fans, covering most common cooling fan types on the market. Simple terminalblock connection brings convenient wiring without complex configuration. Compact module size saves space inside computer chassis. It effectively avoids constant highspeed noisy fan operation for daily use. Perfect for desktop PC modification, industrial cabinet heatdissipation adjustment and DIY cooling projects, it is a practical accessory for hardware enthusiasts and equipment maintenance work.
