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 ...

As the amount of power dissipated by personal computer's CPU and other heat sources has increased, brushless DC fan control has progressed through several levels of improvement to keep temperatures ...

Trying to get AIO Fan speed back to MB (BIOS says no CPU fan reported, but it can be ignored). Temperatures are not an issue. The thing is, no included cable, and the connector on the Fan Controller ...

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 ...

Sometimes you need to generate a pulse-width-modulation (PWM) signal for your circuit to simulate a certain behavior. The technique described here generates a simple programmable PWM signal for less ...

Not cheap, but freakishly good though. Noctua today announced PWM versions of its renowned NF-P12, NF-B9 and NF-R8 fans. Having received more than hundred awards and recommendations from the ...

It took me a while to remember exactly when the last time I did a CPU cooler for Cooler Master was, and I realized it was the Hyper 212. This cooler in the Hyper family has to be, even to this day, ...

CPU_FAN and CPU_OPT are entirely different and serve distinct purposes in the context of a computer cooling system. CPU_FAN or CPU Fan Header is the primary 4-pin fan header on a motherboard, and it ...

Typically, CPU fan noises are heard when you reboot your PC (the whirring sound you may have heard upon startup) and it goes on to decline as the startup process completes. The purpose of fans on your ...

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 ...
