Pi4 + Navio2 heatsink

[sundru]

Now that the pi4 has a lot of processing power, any recommendations for the largest heat sink can fit on the pi with the navio2 hat on ?

I have lots of programs running and cpu is constantly around 80% and getting thermal throttling messages which would like to avoid.

Would something like this fit ?

thanks

You need to have the Navio2 card tightly secured to the Raspberry (no way to do that with this heatsink) or you can try to use a flat ribbon and have the Navio2 card on a separated vibration free platform.

You do not need a large heatsink
