“When I first got the latest Pi I also bought the official Pi case. However, when I switched on my new Pi for the first time the first thing I noticed was a temperature warning icon flashing on and off when it was booting! My room was also getting noticeably hot when the Pi was switched on.
I am pleased to write that since I received my new Pi 4 case the “over temperature warning (80-85C)” icon has yet to appear! So this new Flirc case gets a 5 star rating from me!”
