“Nice case with screws, good finish and fit. Seems to work for me. Pi4 running at 40C and case feels warm to touch. That's with motioneyeos and two basic cameras.”
“So far this has been an impressive heatsink passively cooling my 4B under load. One feature I would like is some 2/3mm threads on top so Hats can be attached”
“To avoid overheating you need something better than the standard case, a fan defeats the object of silent running this does a pretty good job, second purchase.”
“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.”
