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 way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

Modern processors, like those from Intel, are helping designers achieve high-performance levels from compact processors, previously unattainable, with reasonable power dissipation levels and easier to ...

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 ...
