Webb3 juli 2024 · These are the settings for my CPU fan, but yours will differ, depending on the size and quality of your fan. 12.5% may be too low for most heatsinks, which are on the smaller side. Your CPU fan will likely have an option for a target temperature, in degrees Celsius, and a minimum speed, either in percentage or RPM. Webb5 juli 2024 · This post addresses all three issues regarding how to PWM a 3-pin PC fan with an Arduino. 1. You need a PNP Transistor. Most tutorials show an NPN transistor driving a motor as a low-side switch. However, the problem with this approach is that you are switching the ground (GND) path. This method doesn’t provide a return path when the …
