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 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 ...

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 ...

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 ...

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 ...

[hedgehoginventions] wrote in to share a little modification he made to his video card in order to keep it from overheating during strenuous 3D tasks. Having swapped out the stock cooler on his Nvidia ...

I have an NCase M1 and an open air GPU cooler so I use two fans at the bottom of the case to pull in cool air, displacing the hot air exhausted by the GPU. I'm currently using motherboard temperature ...

My recent build has been nothing but headaches. Everything is stable and functional now. However, my CPU fan runs full speed 24/7. So that hinted to me that something was amiss. HW Monitor and ...

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 ...
