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 ...

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 ...

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 ...

Noctua today released its new NH-L9x65 low-profile cooler and a 4-pin PWM version of its popular NF-A6x25 60mm fan. While the latter adds PWM support for automatic speed control to the proven NF-A6x25 ...

Pulse-width modulated motor drives are becoming the dominant method of variable speed motor control, and are being used not only in industry, but in applications as diverse as electric vehicles and ...

For those of you cooling enthusiasts, you probably know Noctua by now and they make great cooling products, so when they decided to introduce their new NF-F12 PWM fan, we were more than happy take a ...

The TC665 is an SMBus PWM fan speed controller with fan fault detection intended for use with brushless DC motors. This device permits temperature proportional speed control and therefore accomplishes ...

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 ...
