Review on Geekworm Raspberry Aluminum Passive Only Silver by Jack Bhowmik

I have this Raspberry Pi 4B case that I will be using outdoors for astrophotography with my telescope. I needed something that would physically protect the Pi from bumps and dents and keep it cool. I also run on battery so not having to use a fan is a big plus. This case design is an improvement over the Flirc concept, which uses an aluminum block to dissipate heat to the case body, but cools more components and has fins on the case for additional heat dissipation. The body is strong and heavy. In my tests it ran about 5-10 degrees lower than an iUniker case with an active 40mm fan (3.3V). Since the case has a large thermal mass, it takes a long time to reach its maximum temperature and is even better able to withstand short temperature spikes.
