“This heat sink is insufficient for my new Raspberry Pi 4 which seems to thermal throttle more or less all the time in a PiBow Coupe 4 case. The heatsink is also very hot to the touch.
Taking the Pi4 out of the coupe case helped a little in that it's not actually throttling at idle.
Pretty disappointed. Can I put a fan shim with this and a PiBox 4 case?”
