“I bought this for a new Pi 4B that I am setting up for Home Assistant. It's quite big and only fits one way round. It has to go sideways across the long axis of th Pi, or it fouls on the connectors. Other than that, it's bigger than the other heatsinks I have used on Pi 3B and Zero projects, so it should be good.”
“Perfect. I’ve used hundreds of these for Pi4 projects. Nice snug fit, and they stay in place. Only a small surface area is stuck to the processor but it does the job well and has no issues running Pi4 lightly overclocked and manages heat dissipation well.”
“I did chop out a couple of fins on the heatsink - this enabled it to cover more of the heat producing areas without fouling the camera port. I can't really say that the pi runs much cooler than before though”
