Through this article, Controlling the brightness of an LED with Raspberry Pi using PWM, one would learn how the brightness of an led can be controlled using the PWM signal Here #PWM stands for Pulse Width Modulation This is a technique that can be used to control the speed of a #dc motor or the #brightness of an led. The fan is connected to the 40pin Raspberry Pi header and comes with 3 wires (5V, GND, and GPIO) since the blue wire is used to control the fan by software using PWM You won’t need to mess with any settings, and updating Raspberry Pi OS to the latest version will take care of everything automatically. To verify this, I hooked up the official fan to a pi 3b I use for GPIO testing I plugged the blue wire into GPIO 12 since the standard pin (GPIO 14) doesn't have the hardware PWM you need to exceed 7kHz Then I used sysfs to enable PWM control and verified that I could finetune the fan speed by changing the duty cycle A couple more notes.

Hook up this 5V Mini Cooling Fan and prevent your hardworking Pi from overheating!. PWM in Raspberry Pi PWM is a technique of controlling the output voltage by varying the Duty Cycle of a stable DC voltage signal at fixed or varying frequency thereby allowing you to obtain an average output voltage level anywhere between the minimum and maximum signal level The two main PWM parameters are Period and Duty cycle. A heat sink is enough for most Raspberry Pi 3 applications and a fan is not required An overclocked raspberry pi should use a fan On kodi, if you do not have an MPEG2 license key, then you might get a thermometer icon, which indicates the need for either a license or a fan The Raspberry Pi 3's CPU is spec'd to run between 40°C to 85°C.
