TFL (No. 1): The lowest temperature channel PWM setting, when ON state FAN1 PWM minimum is 40%, when OFF the minimum PWM of FAN1 is 20%. Support all within 12V 5A fans, synchronous rectifier output, high efficiency!
The High Temp Alarm 12V PWM PC CPU Fan Temperature Control Speed Controller Module would be suitable for people who wish to monitor and regulate the temperature of their PC CPU fans.
