Upon startup, the controller circuit sets the fan voltage to maximum and monitors the tachometer input. Once the signal is stable (1.5 to 2.0 seconds later), it will attempt to use the 4 pin PWM ...

Maintain a given temperature inside a case using PWM fans, a PID regulator and a temperature probe. Regulate temperature in case indpendently of the main computer. Build fan controller out of ...

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 ...

Most of us using desktop computers, and plenty of us on laptops, have some sort of fan or pump installed in our computer to remove heat and keep our machines running at the most optimum temperature.

Cooling specialist Aqua Computer has unveiled the Quadro, a combined fan and RGB LED controller supporting four fan channels and up to 64 individually addressable LEDs. Designed, the company claims, ...

Most of us using desktop computers, and plenty of us on laptops, have some sort of fan or pump installed in our computer to remove heat and keep our machines running at the most optimum temperature.

Modern motherboards may come with RGB addressable headers, which allows one to synchronize additional lighting accessories with those found on the main board itself. But if you prefer to go entirely ...

While there still are a few purists out there that really do prefer the finite control that a slider or a turn dial offers for exacting control over their fans, most users are looking for something a ...

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 ...

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 ...

The scheme in Figure 1 reduces system acoustic noise by running system fans at their optimum speeds for a given temperature. IC 1 combines ±1°C-accurate temperature measurement of three temperatures ...

If your computer's running a little loud for your tastes, it's probably because your fans are running at full speed—even if they don't need to be. Here are a few ways to manage your fan's speed so ...
