Zynthian V5 gets a 25% extra power from the RPi4 by overclocking the CPU up to 2 GHz. For this to work properly, we need to evacuate the heat generated by the RPi4. As we didn't want a fan making noise and pushing dust inside the case, we decided to use the aluminum case as a huge heat-sink. This is achieved by the thermal block, a solid aluminum block that closely contact with the RPi4 chips and serve as a heat-highway to the aluminum case bottom, and from here, to the rest of the aluminum case. When your zynthian is working hard, or when external temperature is high enough, you will note the V5 case is hot. This is good because it means the thermal block is doing its job of transferring heat from inside to the aluminum case body, where it's dissipated to the ambient.
