How to control a fan to cool the CPU of your RaspBerryPi

Hate to burst your bubble and the entire premise of this article but you really perhaps could have researched better before convincing folks that this is the only way to add a fan safely because of some false GPIO pwr limits. The current limit is only for the GPIO outputs, but not the 5V supply on the same header. You don’t risk “blowing” out anything by running a small fan off the 5v pins 4 and 6 as they are direct header feeds.

Certainly not a waste, your effort and script is worthwhile, but the more I see this posted the more people keep spreading the idea that they will blow up their pi by adding a simple 40mm fan and that’s just not true!
