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 ...

Proper thermal dissipation is an essential rule for nowadays electronics. The best operating temperature for the electronic components is 25 degrees (standard room temperature). Thermal dissipation in ...

This circuit is a fan controller which is using the pulse width modulation (PWM) method. It is tiny (33.78mm x 54.76mm) and easy to build. Functions of the circuit parts are listed below; VR1: 10 K ...

So my PC was noisy and I invested in 120mm Akasa Apache fans. Now I have 4 Apache fans (2 on the CPU cooler), 1 sucking the air out at the back and to balance the pressure, one Apache blowing cold air ...

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 ...

Cooling electronic systems has always been an important design consideration. As electronic systems continue to shrink and become more powerful, heat dissipation isn't just important—it's a critical ...

[Alan] noticed that his external hard drive was getting quite hot to the touch after a few hours. He says that it was probably designed to handle the heat sufficiently, he thought it would be fun to ...

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 ...

With my last fan controller review for BitFenix, I covered the basics on what makes for a good fan controller in my opinion. Those are things like controls that aren't easily bumped changing your ...

The Arctic P8 MAX looks pretty much as you would expect, It’s an 80mm fan, so it’s pretty small. Of course, that’s not much use in most mid-tower or most standard PC builds. However, there are plenty ...

Here is an example of the built circuit on a small piece of stripboard. The 2p coin gives an indication of size. I have not included the diode D1 in this example. Side view. General layout of ...
