PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...
TEMP_OFF = 35 # Temperature below which the fan is off (PWM 0) TEMP_FULL = 65 # Temperature above which the fan is full speed (PWM 255) # PWM range for pigpio (0 = off, 255 = full speed) ...
The MAX31740 is a sophisticated, yet easy-to-use fan-speed controller. It monitors the temperature of an external NTC thermistor and generates a PWM signal that can be used to control the speed of a 2 ...
The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...
