The Orange Pi 5 Pro was released not long ago, I bought one right away. It took half a month to ship from China Mainland, and I just received it 2 days ago. I did this simple test to figure out the best heat dissipation method. The test results should also be applicable to a number of single-board development boards such as Raspberry Pi. Hope it helps. blog.ensonyan.com – All Rights Reserved.
