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 remove the heat generated by the RPi4's components. As we don't want a noisy fan, prone to failure, pushing dust inside our nice case, we are using the aluminum case as a huge heat-sink. This is achieved by the thermal block, a solid aluminum block that closely contacts with the RPi4's chips and serves as a heat-highway to the aluminum case bottom, and from there, to the rest of the aluminum case. When your zynthian V5 is working hard, or when external temperature is high enough, you will note the V5 case getting hot. This is good because it means the thermal block is doing its job of transferring heat from the inside to the aluminum case body, where it's dissipated to the ambient environment.

Having understood all this, you may realize '''this is a key step for getting your V5 working at 100%''' of its capacity, so don't be in a hurry and take your time to do a good job. Let's start!
