Questions about this item

Will the on-board AMD Ryzen 3700 2.3GHz processor ever need to be replaced separately?

The processor is soldered to the board, so it cannot be swapped out alone; if it fails the whole MNN1K motherboard must be replaced.

What thermal limit appears first when the Ryzen 3700 runs at 2.3GHz under continuous load?

The laptop cooling solution built for the Inspiron 15 5585 chassis determines the throttle point; the board itself has no separate thermal specification.

How much fan noise and heat should I expect from the MNN1K board during all-day operation?

Noise and temperature depend on the Inspiron 15 5585 cooling assembly and BIOS fan curves, not on the bare motherboard alone.
