Raspberry pi 4 Heat Sink Locations:

When using the Raspberry Pi 4, in most cases, heat sinks are recommended. See photo above for where standard heat sinks are placed. The following list describes where heat sinks are placed on the Raspberry Pi 4:

CPU – The largest square heat sink is placed directly on top of the central processing unit (CPU) chip.

RAM – The medium sized rectangle heat sink is placed directly on top of the RAM chip.

Network – The smallest square heat sink is placed directly on top of the Network controller chip.
