Pwm Fan Controller. Yes there are controllers like corsair commander pro fan controller, but that is controlled by software. Make a Fan Controller with Arduino.
Without PWM, fan speed can only be adjusted. It is one of the best budget items you can choose for your PC. PWM Control: The prevalent method currently used for controlling fan speed in PCs is low-frequency PWM control.
Now, PWM (pulse-width modulation) is, in layman's terms, what allows the computer to automatically regulate fan speed based on temperature readings.
Having this fan hub you can easily push your computer to the limits.
Without PWM, fan speed can only be adjusted. Control (PWM) is the input for PWM pulses. Make a Fan Controller with Arduino.
