I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

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 ...

The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...

The simplest of fan-control schemes an on-off switch is simple but inefficient, because it provides more cooling than necessary most of the time. When The simplest of fan-control schemes — an on-off ...

Speed reporting (the "RPM" wire) is a pulse per rotation, so the only way it'd actually be OK is if both fans spun at exactly the same speed (unlikely due to manufacturing tolerances and varying ...

Advanced Thermal Solutions, Inc., ATS, has introduced the FSC-200 Fan Speed Controller for providing precise management of fan speeds during thermal management studies of electronic devices. Advanced ...

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 ...
