We're running a Raspberry Pi 2 B as a Tomcat-Server and meanwhile it became quite warm so I'm thinking of using one of the old CPU-Fans (12V) we're having around.
Unfortunately I couldn't find any proper documentation how to do it with my Raspberry. For the first model I could find some useful information which referred to the usage of holes close to a capacitor. The black and the red cable should be used, the white one removed.
On my model I couldn't find them, just "run" holes, but according to the information available online those have a different purpose..
Some other sources refer to the usage of the GPIO-Port, but so far I have no idea what to do with my Germany-coloured cable. Should I just cut off the yellow line?
And is it safe to use it? And which Ports should be used? One fella here seemed to have used a 14V pin and his Pi died: How to connect a 12V fan sensor wire to the Pi
What would you recommend me to do?
