Pisound + Pi4: Cooling?

#1

Hi I haven’t got one yet, but looking at the heat-trapping structure formed by any pi-hat, I worry a bit about cooling. Pi4 needs a fan even without a hat, and as the hat likely obstructs airflow, fan support seems to become more urgent.

Q:
Location: Where do I put that fan? Do I potentially need a new case? Does yours have space for it?
Power: Do I still have a GPIO pin left to power the fan? If not, is there an alternative way to power it?

Thanks
Arjan

Check @rbn’s post here: PiSound with Raspberry Pi 4 - at the moment we don’t have an official guidance on how to go about cooling, but rbn’s solution may work.
