A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

A good way to reduce acoustic noise in a system is to adjust the cooling-fan speed as a function of temperature. The standard way to do that (shown in simplified form in Figure 1) includes an IC that ...

Proprietary components are the bane of anyone who dares to try and repair their own hardware. Nonstandard sizes, lack of labeling or documentation, and unavailable spare parts are all par for the ...

I have an NCase M1 and an open air GPU cooler so I use two fans at the bottom of the case to pull in cool air, displacing the hot air exhausted by the GPU. I'm currently using motherboard temperature ...

It's recently occurred that I need to drive more fans than my motherboard has fan headers. These are four-pin PWM fans and the motherboard headers are also four-pin. As I understand it, the pins are ...

Pulse-width modulation (PWM) peripherals have enjoyed a long association with microcontrollers and power control, starting with motor control and power conversion. For the most part, these ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...
