It's actually not crazy on Ingenuity: vacuum really isn't an issue for most chips, the epoxy packages are totally okay from 0-1atm. The temperatures are also kept benign - One of the advantages of being in a near vacuum of the Martian atmosphere is that heat transfer is very slow. Ingenuity keeps to a fairly narrow (-20 to 60C iirc) temperature range even without substantial power spent on heaters. It gets warm during a heat-soak event after flying, and on the cold side, it doesn't get below the temps allowed for the li-ion battery. Note that it isn't designed to survive a bad martian winter, though this is mostly due to decreased power generation rather than lower temperatures.
