This is a simple project that came about from the need (or want) to drive a water cooling pump from a PC board that did not have fan curves that could be modified. Low temperature fan PWM outputs were ...

This is an implementation of PID control for a PC Fan following Intel's PWM spec. This is my Arduino implementation of PWM Fan control using a 10K NTC and PID. I rewrote the timer implementation on ...

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 ...

This circuit is a fan controller which is using the pulse width modulation (PWM) method. It is tiny (33.78mm x 54.76mm) and easy to build. Functions of the circuit parts are listed below; VR1: 10 K ...

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 ...

The TC665 is a System Management Bus (SMBus) PWM fan speed controller from Microchip that was developed for use with brushless DC motors. The device features FanSense™ protection against fan failure ...

The popularity of PC fan controllers has been increasing over the last few years, and we see more case manufacturers including fan controllers in their products as little extras. The increase in ...

Pulse width modulation has been around for nearly two decades in the realm of fuel pump control at the OEM level. This method of controlling an electrical component allows for less stress on electric ...

Deciding between PWM and DC case fans can be confusing, but it’s important for the optimal performance of your computer. In general, PWM fans are quieter, more controllable, and more durable than DC ...
