“Seems to get quite warm and temperature gets higher when intensive processing. Will buy some longer screws and spacers and mount it vertically to see if it helps to reduce the operating temperature.”
“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.”
