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 ...

The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...

A partial solution to quietening noisy PCs can be to reduce the speed of internal cooling fans. Low-cost fan speed controllers are available, but they often employ inefficient, heat-generating linear ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

This post is a quick sequel of my previous article jam-packed with my personal experiences and observations while I was fiddling with standard 4-wire PC cooling fans. Today I will be talking about the ...
