“A very nice product. My Rasberry Pi 4B is 'crunching' numbers in seti@home project 24/7, and also is my major computer now. System is packed in a little transparent plastic freezer box, with an external USB hard disk... Fan SHIM keeps the temperature in an optimal level, thanks to it's clever ON/OFF configuring options. LED is a nice bonus, acting as a night light too.”
“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.
