Overview

• On August 1, Nintendo Japan’s support X account officially advised that both Switch models should only be used in environments between 5°C and 35°C to avoid heat-related malfunctions.
• Early July reports from Japan detailed Switch 2 units overheating with fans at maximum speed and unexpected crashes, even during less demanding titles like Splatoon and Pokémon.
• Record summer temperatures in Japan reached 41.2°C, highlighting the challenge of using hybrid consoles without air conditioning.
• No hardware updates have been announced to address the thermal limitations beyond this advisory.
• Switch consoles’ recommended operating range is narrower on the cold end than comparable devices such as iPhones, underscoring inherent cooling constraints in Nintendo’s hybrid design.
