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 ...

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 ...

Here's an odd one. I've got a site with two C2921 units (one from an ISP and one doing internal routing) where the fan speeds differ greatly. The unit the site controls is mounted directly underneath ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

This post is a quick sequel of my previous article jam-packed with my personal experiences and observations while I was fiddling with standard 4-wire PC cooling fans. Today I will be talking about the ...
