“I bought these for my two rpo3. Very quick delivery and easier than pie (sorry) install. My own mistake that I had a case with inbuilt heatsink on one of them but I put it onto the LAN chip instead. Recommended”
“I purchased one of these to help my Pi stay cooler as I'm using it as a media center and it's on a lot. These heatsinks help a lot but it's a good idea to leave the lid off of the case too, this helps too.”
