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 ...

I have a Darlington transistor to keep cool. It is a lovely chunky TIP147 in a TO247 package, attached to a PC heatsink (£6 from ebay) to get the heat out. PC heatsinks are great as they often include ...

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 ...

Designers of today’s electronic products are packing more performance and functionality into smaller and smaller systems. The increased performance often generates additional heat, which degrades the ...

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 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 ...

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 ...
