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 ...

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 ...

A good way to reduce acoustic noise in a system is to adjust the cooling-fan speed as a function of temperature. The standard way to do that (shown in simplified form in Figure 1) includes an IC that ...

How to build a proportional controller that starts a cooling fan when circuit temperature passes a threshold, speeds up the fan as the temperature rises, and slows down and stops the fan when the ...

I searched a little bit in this section, and didn't come up with too much on fan controllers (at least nothing regarding specific brands). The only thing that stood out at me was from the Star Trek ...
