Let's say you have a fan mounted above some Raspberry Pis that sometimes overheat. So it doesn't get used very often.

Surprising insight of the day: you can point it at yourself if it is hot in the home office in the summer!!

Equality for people and Pi's! Not just Pi's get to use the fan!!

(Like that AC we had decades ago at that first university institute I worked. It was for the computers in the computer room only, not the people who got to sweat.)
