Does Vertical vs. Horizontal Actually Matter?

Both Sony and Microsoft designed their thermal vapor chambers and cooling blocks to operate reliably in either orientation. The viral reports that PS5 liquid metal "leaks vertically" were traced to previously opened or damaged consoles whose hermetic APU foam barrier had been compromised. In an undamaged console, gravity does not cause liquid metal to spill.

The True Danger: Thermal Recirculation

The number one cause of jet-engine fan noise and premature silicon throttling is thermal loopback: when hot exhaust air (often 55°C–65°C / 130°F–150°F) cannot leave an enclosed bay and gets pulled right back into the intake. Both consoles need at least 10 cm (4 inches) of unobstructed clearance on all intake and exhaust vents.

Stand & Cable Bending Rules

• Always use the stand: In horizontal mode, the PS5's curved plates choke bottom airflow without the stand clips.
• Xbox Series X Chimney Effect: The top green-accented grille is the primary exhaust. Do not place objects or a low shelf within 10 cm of this top.
• Cable strain relief: Thick HDMI 2.1 and power cables require ~5–7 cm bend radius at the rear.
