How to Tell Whether Your Mac Fan Is Broken (3 Steps)


Hold your hand next to the heat vents. On a desktop model, the vents are on the back, near the top of the case. On a MacBook or MacBook Pro, the heat vents are on the bottom of the case, in the crease where the screen folds down. If you feel heat flowing out of the vents, your fan is blowing heat out.
Press your ear to your Mac's case. With either a MacBook or MacBook Pro, you should press it to the bottom of the case. If your fan is running, you hear a quite whirring in the case.
Feel the bottom of your case. During normal use, your Mac's case becomes very warm. If your fan is broken, the case becomes extremely hot.
