The problem is not the outside temperature, but the small difference from the inside one preventing the circuitry inside the dish to cool down. Also the way it is engineered doesn't help: it draws about 100 Watts of power, but the entire circuitry is enclosed in a plastic container with no way to exchange heat with the outside, and the heating parts are kept in "contact" with the metal plate working as heatsink through thermal pads which seem just too thick to me to transfer enough heat.
The metal plate should be helped to dissipate all that heat, but that would require flowing air, which is not an option in a closed box. According to a teardown video, there's no way to remove the metal plate without destroying the device, but one can still reach it and that would make possible for example thermal-gluing a metal pipe to it, then build a liquid cooling system by pumping the liquid through a better external heatsink with real fins.

- sfblah 5y ago100 watts seems like a lot for a receiver. Any idea where all that energy is going? Signal amplification?
- eightysixfour 5y agoIt also has to send using a phased array as well.
- sfblah 5y agoOh right duh. Thanks.
