How to check your Mac’s temperature and keep it cool

Macworld While people are at the greatest risk from high temperatures during the summer season, your Mac can also be at risk. (People can be water-cooled, and no current Mac offers that option, though some have tried.) An iPhone or iPad will warn you when it detects it’s too hot before shutting down, while a Mac may simply suddenly power off. If it doesn’t power down, you may be running it too close to its maximum capability and putting a lot of additional wear in the process on components that might fail later during other seasons. Knowing the temperature is one thing. The other is: how hot should your internal components run? Apple says you should only use a Mac when the ambient temperature–the temperature around you–is in the range of 50°F to 95°F (10° to 35°C) and 95 percent or lower humidity. Internal components produce far more heat than the ambient temperature, with around 100°F or 40°C often the minimum at which they operate in normal indoor cir
