Control Fan With Raspberry Pi. Raspberry Pi PWM Fan Speed Control Embedded Computing Design Fan's ground must be connected to the Collector, and Rpi's ground must be connected to Emitter Begin by confirming you have the latest DTB files to enable efficient fan control
Raspberry Pi Fan Temperature Control [Howto] YouTube from www.youtube.com
By doing this, we have a switch that will connect or disconnect the ground wire from the fan to the ground of the raspberry pi. In order to control the fan, we need to use a transistor that will be used inopen collector configuration

That project was pretty great but I wanted to take it to the next level and add the ability to only turn the fan on when needed by monitoring the core temperature.This way, a noisy fan isn't running all the time. On kodi, if you do not have an MPEG-2 license key, then you might get a thermometer icon, which indicates the need for either a license or a fan A lot of people uses fan to cool down their Raspberry Pi 4, but the fan's noise is quiet problem (in a quiet room)
GeeekPi 2PCS PWM Controllable Fan for Raspberry Pi, Speed Adjustment Fan 40x40x10mm. This built-in functionality on the Pi was only added in late 2020, but everything, of. if you want to control the fan speed you need to use a gpio pin and a transistor control circuit
Raspberry Pi Fan Temperature Control [Howto] YouTube. No installing or writing scripts required, just a simple set of options, and potentially modification of a text file dtoverlay=cm4io-fan,minrpm=1000,maxrpm=3000 This would set the fan to stay on at least at 1000 rpm at all times, and it would go up to 3000 rpm once the Pi's SoC reaches the maxtemp, which by default is 5500 in millicelcius (55°C)
