12V PWM Fan Temperature Controller - Accurate Manual/Automatic Speed Control

Welcome to our shop! This PC fan temperature controller is a versatile device that integrates manual speed regulation and automatic temperature control and speed regulation functions. It supports the control of reverse timing fans and has a PWM control mode for four-wire fan control. The controller is designed to work with a DC12V power supply (can work in the range of 8-18V) and has a current consumption of no more than 20mA. It features a fan interface with a 2510-4P connector (special interface for computer 4P fan) and can withstand a current of up to 3A. Please note that if you need to control a larger current fan, you will need to take the fan power cord separately. The controller's PWM output range is 10% - 100% and it has a working temperature range of -10℃ to 60℃. It comes with a temperature probe (NTC 50K B=3950) that has a temperature resistance of 120℃ for the small black head and 110℃ for the ring probe. The board size of the controller is approximately 34 x 19 x 11mm (excluding the extended interface), and the fan interface extends by 8mm. The factory default values of the setting parameters are low speed 20%, acceleration temperature 30°C, and acceleration width 5°C. To operate the controller, you can use the manual control without the temperature probe by clicking or double-clicking the button to adjust the speed. When the temperature probe is installed, the fan speed will increase smoothly as the temperature rises. We want to ensure 100% satisfaction for our customers.
