If you want to impress your friends in conversation, you should keep track of your Mac’s fans and relay to them how fast they tend to spin during particular tasks. If that doesn’t solve your issue, consider heading to an Apple Store, or another authorized repair shop. In these cases, resetting the SMC often works-this is the low-level controller that manages thermal management and other things.
If the hardware report says everything is fine with your fan, your issue is probably a software one. But look at all the steps carefully, and only proceed if you’re completely confident you can get this done yourself. It’s not impossible, however: check out iFixIt‘s guides if you want to attempt the repair yourself.
I managed to replace my own broken fan on a 2011 MacBook Pro, but the internals inside more recent Macs are a great deal less friendly for home repair. My advice: head to the Apple Store or any authorized Apple repair shop. If you have a broken fan, you need to replace it. Your Mac will test your hardware, and let you know if your fan is broken. Turn your computer off, then hold the “D” key while turning it on. Think your fan might be broken? The first thing you should do is launch Apple Diagnostics, one of the hidden startup options on your Mac. But for the occasional test, it’s nice to have control-just turn things back to automatic when you’re done. I really do not recommend disabling the automatic fan control: leaving your fans on constantly will wear them out and waste energy, and leaving them off will overheat your Mac over time. Turn the fan up and see if you can hear anything.

The same goes if you see a low CPU temperature-say, around 45-and the fans are running at full speed. If you see high CPU temperatures-say, over 80 or 90 degrees-and that the fans aren’t running, you might have an issue. The minimum, current, and maximum speed are shown in that order. For the most part, however, we’re interested in your fan’s current speed.
