Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

I need some basic electrical engineering type help in understanding how fan speeds are regulated. Most case fans these days come with motherboard headers or switches/sliders to control their speeds.

Adding an additional fan to your PC is usually pretty straightforward, but as [Randy Elwin] found, this isn’t always the case with the newer Small Form Factor (SFF) machines. Not only was the standard ...

A partial solution to quietening noisy PCs can be to reduce the speed of internal cooling fans. Low-cost fan speed controllers are available, but they often employ inefficient, heat-generating linear ...

The fan runs constantly in many PCs, which may not even be necessary. A simple controller circuit can regulate the fan speed according to demand. This not only saves energy, it also reduces irritation ...

Following are the best free Fan Speed Controller software for Windows 11/10 PC. The list is in no particular order as every app here has some unique ability. Let us start with a one-stop shop for all ...

The Lutron HomeKit-enabled fan controller makes it easy for anyone to control a ceiling fan from the wall, with their phone, or with their voice. But, it isn't perfect. During the 2019 Consumer ...

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 ...

Am putting together a PC and have run into a problem with the MB/case. The case fan has a 3-hole connector and all system fan connectors on the MB are 4-pin. Case: Fractal Design Define R5 Black ...
