“Quit, works perfectly with the Coupé 4 case. Very easy to set up, and keeps everything well below the throttling temperature. It’s software controlled, so it switches on at whatever temperature you set and switches off in the same way. It keeps noise and power consumption to a minimum and helps to keep the Pi running at full tilt.”
“The idea is good, it keeps the pi cooled, but after a week of usage, it became very loud.
Either build quality is that bad or i received a possible faulty unit.

“Worked with no issues right out of the box. And everything is working as advertised after installing the software. My only complaint is it doesn't turn off when I shut down My pi 4B. It just keeps running as long as the Pi has power.”
