I'm a new Raspberry Pi 4 user. I have bought the Labists Kit which includes 3 heatsinks and a fan.
As far as I understand the fan is connected directly two the GPIO pins (see for example this video that I followed when assembling the kit at 1:49). The kit does not include transistors or other stuff.
When I connect the Pi to the main's the fan starts spinning... all the time. Even when the Pi is shutdown.
Is there a way to control the fan status based on whether the temperature is above a certain degree?
I have found a couple similar questions, for example this one,that suggest using something like
gpiozero Python library to turn the pins on or off... in most examples they use gpio number 18, however I already tried to turn off all pins <= 32 and nothing seems to happen, the fan is always on.
Is there a way to control fan use with the kit provided by Labists without having to solder some transistor or other stuff in the Pi?
Note that the average temperature of the Cpu is something like 32-33 °C so it certainly doesn't need the fan right now. I don't plan to use the Pi for cpu-intesive stuff, so I might simply remove the fan if there is no simple solution.
