Overclocking the Raspberry Pi 400 is easy and gives you an extra performance boost for free. The Pi 400 has been designed to be used without any active cooling. This has been achieved with careful PCB design and a massive heat-sink. Not only does this allow the Pi 400 to run at 1.8GHz out the box but it also allows for some easy overclocking.
In a Pi Foundation blog post Simon Martin stated,
We’ve solved the cooling challenge so users don’t have to give this any thought. Raspberry Pi 400 contains a heat spreader that dissipates the heat across the whole unit, front and back, so that no part of it will feel too hot to touch. In fact, there is enough thermal margin to overclock it, if you’re so inclined.
