I was wondering about a temperature controlled case fan (80mm or 120mm) that has its own temperature sensor (not controlled by the motherboard) to control its RPM. Are all of them like this or are ...

I've got a storeroom in a garage that has some stuff in it that is a little more temperature sensitive, and has more variability than I'd like (it also has some equipment that generates a bit of heat, ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

Most of us using desktop computers, and plenty of us on laptops, have some sort of fan or pump installed in our computer to remove heat and keep our machines running at the most optimum temperature.

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 ...

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 ...

Smart ceiling fans—models with wireless remote controls and digital-assistant compatibility—are a relatively new thing. But you can still control a legacy fan if you replace your in-wall switch with ...

As anyone who has worked with their laptop on their lap knows, after a while your computer gets hot. The greater the demands you place on your notebook, such as running multiple programs or using ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...
