The TC654 is a dual SMBus™ PWM fan speed controller with fan fault detection. This device is suitable for brushless DC motors. It permits temperature proportional fan speed control which lowers ...

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 ...

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 ...

Well, I'm using Noctua fans which are damned well made. I was originally going with Redux fans, but I found them too noisy, so I'm going to return them in favour of NF-S12A PWM which come with a 1:2 ...

As the amount of power dissipated by personal computer's CPU and other heat sources has increased, brushless DC fan control has progressed through several levels of improvement to keep temperatures ...
