“I would prefer it covers the sides a bit better. Overall good thermal performance. Just make sure you read the instructions before installing (on pi hut).”
“I wanted passive cooling, so I chose this as it had protrusions for the CPU and memory and ethernet. I cannot write code, so I used the 'Explaining Computers' web site and copied his code to test the generated heat. Running said script several times on the trot, with an ambient temp in a warm'ish room, gave the highest result as 56 deg c. To my mind a good result. Not only that, but it makes a strong, sturdy case as well.”
