I had bought 5 RPi protect my thinking. I wanted to improve the heat dissipation but we understand very quickly that the double-sided tape is partly as an insulator. On the other hand if the RPi is not lying flat but vertically, I doubt the holding of ladhésif that could drop the radiator in the case and came into contact with other components. On the other hand, if you installed this type of radiator said goodbye to the use of cards like for example PiFace who come in contact with the radiator and will no longer be installed. In summary, the setting is very weak.
