“Looks good, keeps temperature to around 45 degrees. I added some self adhesive feet to the bottom of the heat sink. Although heat sink is made of aluminium it adds weight to the Pi too to help stop it sliding around. If your connecting a Pi camera, pop the ribbon cable into the Pi first.”
“The thermal pads were pre applied, but a little aside. I could not remove them to reapply, 'cause they were crumbling. Fortunatly for my use it is quite adequate”
“I like the idea of a combined case and passive cooling solution for a Pi4 - a very elegant solution. The case looks good - I went for black simply because it's better for heat loss. I've set the Pi4 up as a web server with SQL lite, primarily for developing middleware web applications in Python. The case gets warm, but not hot, in operation - so it works for me. I've added four black adhesive foam feet on the base to (1) allow air to flow underneath better and (2) stop it slipping around on smooth surfaces - might be an idea to include these with the case?”
“Protects the system extremely well, very effective heat sink. The only suggestion I would make is it might be helpful to provide two screw holes on the top that could be used to attach things to the case (i.e. sensors, camera, small PCBs). All in all a great case, will be buying another.”
