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 ...

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 ...

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 ...

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 ...

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 ...

PC running hot? Replacing your case might not be the solution.

As anyone who has worked with their laptop on their lap knows, after a while your computer gets hot. The greater the demands you place on your notebook, such as running multiple programs or using ...

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 ...

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 ...
