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 ...

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 ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

Cooling fans are widely used and are extremely important in electronic devices, especially for those constantly running. That includes power supplies, servers, computers, and telecommunication ...
