Control CPU fan speed on Windows using third-party software. There is a lot of third-party software that comes with the ability to control the fan’s speed on Windows manually.

Where Lutron’s fan controller has five buttons to control on, off, fan speed up and down, ... (Leviton’s model DD00R, $20 each) if the fan is on a three- or four-way circuit.

On most laptops, an internal fan will cycle on and off, as needed, to help keep your system cool. You can control laptop fan speed, the frequency with which your fan turns on or off, or other ...

The circuit of Fig. 1 also controls the fan with a 100-Hz PWM signal, generated by the open-drain output of U1 (the MAX6639, a 2-channel temperature monitor with dual automatic PWM fan-speed ...

• Fan speed control circuit • System airflow. A fan's speed can vary 5% to 10% when new, unless tightly controlled by the fan specification, which adds cost.

When your fan-speed control relies on a microcontroller, your system's cooling is subject to software failures and bugs, so you should design in a backup control system. For example, you can use a ...

As Moore's Law plunges us into the realm of multigigahertz processors and PCs with gigabytes of RAM, engineers face the task of removing the heat that these state-of-the-art components produce.
