“Once the Pi 4 has a monitor attached you start to see more heat than just a finned light copper block stuck to the processor will redistribute. This robust solid case lets the heat spread into the air without a fan, you can expect 25°C above ambient running a GUI and browser, rising to 40°C above ambient at full load without throttling. It's a very impressive case.”
“Great heatsink purchased a few now to colour-code my pis.
They have kept things cool without any active fans, and also make handling much simpler. The extra heat pads are also good if you make any mistakes or need to do some tinkering.”
“Very easy to fit and the spare pads were very handy. There might be a market for one with mechanical connection points to allow easy bolting into another case (with suitable ventilation)?”
“Bought this to replace an official case as the Pi was overheating despite the official case having a fan fitted, this does the job perfectly, no more overheating, this will be my case of choice in the future. The only drawback is it limits access to the GPIO pins, particularly for boards that connect here eg Phoscon RaspBee II.”
