I have just powered up and updated my BBAI one hour after delivery of same. The board shut down at 95 degC, which it reached within fifteen minutes of power-up! After waiting for cool down and restarting, I upgraded all the software as advised, by blowing on the heatsink during the process. When finished, I ran 'top' command and the board shut down after 10 minutes - reaching 80 deg C. I restarted again as before without running a command and the board shut down on over-temperature again with only the standard processes running - no user commands.
The unit obviously needs a fan - something not mentioned in the literature. A fan cape is purchasable for about $35, but really ??? I would not have bought the board had I known, since it was destined to become part of a remote and unattended SDR (Radio Receiver) and fans are a no-no. This does not seem to be a software or firmware fault - it is a design issue - and the board should be sold with fan, as it is not fit for purpose as-is. Very disappointed, as I have sunk further cost because I bought a cape for the thing - which is yet to arrive. Gah!!!
