“It is a fan and it works, but the case that comes with the pi 4 bundle isn't the case it fits in, or else I can't work it out. I've detached the fan from its own housing and stuck it to the case and it works fine, but not as easy as expected.”
“Not sure if it's a limitation of the pi or the fan but there seems to only be three speeds: off, medium and high.
Could also do with a corresponding hole on the official pi case (though that's really a complaint of the pi case).”
