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 ...

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 ...

This Processor Fan Control circuit is intended to be used with relatively old PCs, since more recent models generally have a fan control circuit already integrated into the motherboard. These ...

A cooling system can sometimes be a buzzkill. You drop your badass engine into your badass hot rod, and then you remember you've got to keep it cool. As an afterthought, you order a big aluminum ...

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 ...

The default for any control project here in 2019 was to reach for a microcontroller. Such are their low cost and ubiquity that they can be used to replicate what might once have needed some extra ...

It is clean looking, easy to install and use, and it offers plenty of power and finite controls that most enthusiasts are after. Thermaltake has delivered once again, and the Commander FT comes highly ...

Given that you could run 5-6 fans off a single header without overloading it, it seems to me the main reason to go with a controller rather than a splitter would be to make the wiring easier.

Keeping a modern computer nice and cool has transformed into a large and active segment of the aftermarket PC accessories world. There are seemingly endless arrays of products out there to help you in ...

NZXT's GRID+ V2 is where all fan controllers will eventually go! It is small, powerful, can be hidden, and once the CAM software is involved, there truly is endless controls offered to the user. We ...

The Lutron HomeKit-enabled fan controller makes it easy for anyone to control a ceiling fan from the wall, with their phone, or with their voice. But, it isn't perfect. During the 2019 Consumer ...

Here is an example of the built circuit on a small piece of stripboard. The 2p coin gives an indication of size. I have not included the diode D1 in this example. Side view. General layout of ...
