A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

The AMC6821 is an intelligent temperature monitor and pulse-width modulation (PWM) fan controller. It is designed for noise-sensitive or power-sensitive applications that require active system cooling ...

Proprietary components are the bane of anyone who dares to try and repair their own hardware. Nonstandard sizes, lack of labeling or documentation, and unavailable spare parts are all par for the ...

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 ...

You can control your CPU fan in Windows 10 using software like SpeedFan. Fan controllers with touchscreens or knobs offer easy ways to manage fan speeds physically. This article explains how to ...

Sometimes you need to generate a pulse-width-modulation (PWM) signal for your circuit to simulate a certain behavior. The technique described here generates a simple programmable PWM signal for less ...

Arctic has a long history of producing a wide range of quality cooling products including CPU coolers, GPU coolers and fans. It's only recently that they have diversified into different markets like ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...
