Review on Raspberry Heatsink Designed Aluminum Pi Metal02 by Alan Massey

I use a Home Assistant automation server (aka Hassio) that integrates all my home automation and security sensors. This Pi works 24x7 - 365 days a year so I need a very reliable setup for it. The current case was a magnetic plastic case with 2 mini fans and a heatsink attached to the Pi chipsets. This works well, but the fans wear out (and get very noisy) after 4-6 months of continuous use. CPU usage for Home Assistant tends to stay below the 10% average, so I decided to switch to this passive heatsink setup (about 3 weeks ago) and didn't have the first issue with my setup, just this passive one cooling setup. . My only addition is a side stand that can hold the shelled Pi securely upright on its side. This ensures maximum airflow to both sinks from all directions and I think this is the smartest way. I could even install an external fan to provide more airflow over the sinks if I find it necessary. but with my setup and low cpu usage it is currently not needed. This kit includes all the necessary screws and thermal transfer stickers needed to securely attach the heatsinks to either side of the Pi board. great design and execution (note: there just aren't any instructions, but they're so simple you won't need them).
