Are you still worried about the heat dissipation function? Do you want to have a new heat sink? The new Raspberry Pi 4B aluminum heat sink could help you solve this trouble. These pure aluminum heat sinks include thermal tape that transfers heat efficiently to the heat sink, providing additional cooling for the IC. The contours of these heat sinks are perfectly adapted to the Raspberry Pi 4B standard.
