Can the xbox one S actually overheat?

Do you know that?

Everything can overheat. Naturally!

Sure, each console can overheat if it gets too little fresh (cool) Lutft.

Absolutely. Most of the time you notice it at faltering, slowed frame rate to standstill / hang. The "Ring of Death" in the first Xbox was also a part that was raised by overheating and tore solder joints, at least someone told me.

Stand upright and put on a fan is good.
