High-frequency dc fans feature pulse-width-modulation (PWM) fan-speed control that eliminates motor commutation noise. The PWM ramps up linearly from a 20% duty cycle up to the fan's maximum rated ...

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 point of this guide is to show the latest and greatest in fan control technology on Intel Z270 motherboards and to help you understand what each brand has to offer in their high-end products. I ...

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 on, the fully powered switch-controlled fan ...

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 ...

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 ...

Most newer computer motherboards are equipped with pulse-width modulation controllers that can be used to control the revolutions per minute of the internal cooling fans. Whether one of your business ...

Windows PCs and laptops require a dedicated fan to support heat dissipation. The fan helps keep the hardware cool and ensures it doesn’t overheat in any intensive work or task. During peak performance ...
