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 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 ...

[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 ...

Typically, CPU fan noises are heard when you reboot your PC (the whirring sound you may have heard upon startup) and it goes on to decline as the startup process completes. The purpose of fans on your ...

Speedfan, is right not an option, as it does not support my motherboard. I don't like MSI dragon center, and I dont want to have to go to BIOS to adjust fan speed. What software is there, aside from ...

Case and PC hardware component manufacturer LIAN LI has announced the introduction of a new addition to their range of IAN LI UNI Fans, with the unveiling of the AL120 PWM fan. Offering simple ...

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 ...
