“After buying my first Raspberry Pi 4 I have to say the additional heatsinks were attractive, easy to install and work without issue. Great product....”
“The heat sink set is just perfect but just be aware that HATs and fans might need a header extension to make them fit (i.e. the argon fan HAT and the heat sink doesn't work without and extension). Works well and keeps the processor cool enough.”
“This was 4 separate heat sinks (as clearly shown in the pictures) which were easy to fit to the 4 chips. I guess this configuration does not cool as well as the large heat sinks that stick to all 4 chips, but is still a good solution. I have not yet done anything to make the Pi work hard, so I can't say how well the heat sinks actually cool the chips.”
