MacOS – does the Macbook become extremely hot when using Boot Camp

boot-campmacmacos

The bottom of my Macbook becomes extremely hot when I use Boot Camp (Apple's built-in solution for running Windows on a Mac), especially when I play games. Sometimes my Macbook shuts itself down because it gets far too hot.

Why does this happen, and what can I do to cool it down or keep it from becoming too hot?

  • The heat is due to heavy CPU usage. Be sure the exhaust vents on the back aren't being blocked by anything -- if the MacBook is sitting on a blanket or your lap, airflow will be reduced and the fans won't be able to cool as well.

    My two-year-old white MacBook has never actually shut down due to high heat, but I don't use Boot Camp on it. Perhaps Windows is trying to manage the fan speeds itself and doing a poor job of it? (I'm not sure if Windows even controls fan speeds or if the BIOS does it. Correct me if I'm wrong.)
