Questions about this item

Will the microSD slot on this KFNTW board need cleaning or replacement after heavy use?

The microSD slot is a mechanical connector; debris or bent pins from frequent card insertion can eventually require a replacement board.

What limit appears first when both USB ports and the microSD slot run at full speed for hours?

Sustained high throughput on both USB ports and the microSD slot is limited by the shared downstream bandwidth from the laptop chipset.

Does this right-side IO board generate noticeable heat or fan noise during all-day operation?

The board itself is passive with no active cooling; any heat or fan noise comes from the main system, not this daughterboard.
