And one day, you will see an alert popup window that says, “Your startup disk is almost full.”

However, when you have used this laptop for a few years, the excitement is now completely gone as it performs slower and slower. On an iMac or Mac Pro, you can download a free app like smcFanControl or premium app like iStatMenus to monitor the temperature.We all know that feeling… receiving a brand-new MacBook… the smell of the packaging reminds us how smooth this computer will work. On a MacBook, it should be obvious to the touch when a Mac isn’t hot enough to warrant loud fan noise. Fans exhibiting this issue spin loudly all the time, regardless of how hot or cold your machine is. This is different from a CPU or GPU under load. Sometimes, the SMC needs to be reset, and one tell-tale sign is fans that just won’t shut up. The System Management Controller (SMC) is responsible for managing aspects of your Mac including power, battery and charging, sensors and indicator lights, and thermal management features like fans.

If you’re seeing issues like that, it might be a good idea to run some hardware diagnostics or book the machine in for repair. You might get random restarts and freezes, or even see strange colors and glitchy graphics when trying to render 3D environments. This will cause problems with your computer around 3D and other GPU-related tasks. The only thing you really need to worry about is whether your GPU is getting too hot.

Remember, it’s perfectly normal for your GPU to heat up under load, and for the fans to ramp up considerably to deal with it. There’s not a lot you can do about a hot GPU beyond avoiding activities that use your GPU.
