More and more often, variable frequency drives (VFDs) are used for control of fans and compressors in HVACR systems. The benefits are well documented and industry acceptance is such that most electric ...

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 ...

Engine temperatures climb fast whenever you drive, idle in traffic, or run the air conditioning, and your cooling fan quietly ...

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 ...

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 ...

We continue to receive complaints from readers that various PowerBook G4 models get too hot on the underside, and as a result, generate too much fan activity. We previously reported using a cooling ...
