How can I tell what is running my Mac fan?
The first thing you should do is launch Apple Diagnostics, one of the hidden startup options on your Mac. Turn your computer off, then hold the “D” key while turning it on. Your Mac will test your hardware, and let you know if your fan is broken. If you have a broken fan, you need to replace it.
What is making my Mac fan spin?
If your Mac is clean and grime-free and you are keeping your apps and tabs in check and the fan is still spinning frequently and loudly, then try resetting the System Management Controller (SMC).

Why do I hear a fan running on my Mac Pro?
If you hear the fans in your Mac Pro running at full speed and you aren’t performing any intensive tasks, check the enclosure. Make sure that your Mac Pro is locked and fully seated, or that the top cover or access door is closed and locked on rack-mounted models. Some Apple products have vents that let fans bring in cool air and expel hot air.

How can I tell if my MacBook Air is overheating?
How to Tell When Your Mac Is Overheating. There are several tell-tale signs that your Mac is running unusually hot. The most obvious is that the Mac feels hot to the touch, particularly on the underside of the chassis if you have a MacBook. While your Mac is hot, you should expect the fans to attempt to cool it down.
Why does my MacBook Pro keep getting hot?
If your Mac can’t “breathe,” then it can’t cool down sufficiently either. For example, the MacBook Pro sucks in cool air on the bottom of the machine near the right and left edges of the chassis. It exhausts hot air out of the back, behind the display hinge. If you are blocking these vents, your Mac will get hot even under regular load.
