“Well. It's a very tight squeeze to try to fit it in between the IO pins, camera connecter and the screen connecter.
I would like to suggest that you remove one row, and one column of fins from the heat sink.
Then vary the thickness of the base of the heat sink so that it will contact with the memory chip, wifi module and use the two surface mount components next to the memory as registration points for the heat sink.”
“If you choose passive cooling for your Raspberry Pi, this is the heatsink for you! I have a ton of those cheap heatsinks that you get with other cases sitting in my leftovers drawer. This is quality starting with the size. The more surface area the better for passive cooling. The metal used is heavy. The adhesive is strong and allows great heat transfer.
If I had a suggestion, it would be to make this work with the Fanshim!”
