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 ...

Proper thermal dissipation is an essential rule for nowadays electronics. The best operating temperature for the electronic components is 25 degrees (standard room temperature). Thermal dissipation in ...

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 ...
