IT DOESN’T MATTER whether you’re running the latest Mac mini or an ageing MacBook, they all suffer from one unavoidable affliction: heat. The harder you push your Mac’s hardware, the hotter it gets - so every time you do anything taxing, from playing games to editing video, its insides heat up.
The cumulative effect is to stress your Mac’s components and reduce their lifespan, a problem compounded by the fact your fan isn’t necessarily doing all it can to mitigate the rise in temperature. Macs prioritize keeping themselves quiet over cooling your components, relying on their built-in ability to “throttle” the CPU when it hits a certain temperature. Throttling reduces performance while the fan sits practically idle when it should be cooling your Mac.
