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 ...

Part-load efficiency is rapidly becoming the most important measure of energy efficiency in chiller units. Around the world, new environmental standards are increasingly based on a combined part-load ...

The SmartFan Inversion fan-speed controller combines an ac/dc power supply and a dc-fan control/alarm. The controller has a supply voltage from 95 to 264 Vac, and supports 24 or 48-Vdc fans rated to 4 ...

The ZXBM2000 series of controller ICs offers a complete variable-speed solution for two-phase, dc brushless fan and blower motors up to 100 W. The controllers ...

This document discusses the operation of the MAX6650 and MAX6651, two fan controllers with linear closed-loop fan speed control. Temperature-based fan control is a necessity in a growing number of ...

Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

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 ...

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 ...
