“Works fine, looks cool and keeps the SoC around 62 Celsius under light load. The heatsink itself sits around 55 Celsius so it's pretty hot to the touch. The only thing I'm concerned about and the reason I gave 4 stars that there is no reinforcement for the back of the board and it's bending a little bit under the pressure of the heat conducting pads. It's probably nothing but I'm not sure if it's healthy for the BGA solder balls under the SoC.”
“The Pi 4 does get very warm so some form of heat sink is necessary to assist in keeping the device cool. The Aluminium heatsink case does an excellent job in conducting the heat away whereas the plastic case would retain the heat to a greater degree.”
“The heatsink works well. Was surprised to find it makes thermal contact with the USB controller and RAM in addition to the expected SOC. Obviously the whole thing gets very hot, which means its working. I can see it being tricky to use if you use the camera or display cables, but not impossible.”
