Fix MacBook Pro Fans Not Working

Most Macs, excluding the 2015 MacBook and 2020 MacBook Air, feature cooling fans. The smooth and efficient running of these fans is required to keep processors and other electronic components cool. However, you are not often aware of the fans not working issue until something goes worst. Maybe you hear the loud fan noise. Here is how to Fix MacBook Pro Fans Not Working.

How to identify if a MacBook is overheating?

Most of the time, it is hard to tell that the fans are running at an abnormal speed. The reason is that they hum along quietly in the background. When the MacBook overheats, you are hardly able to touch the area around the fan.

Check the CPU temperature regularly to ensure the workload is not putting too much pressure. If you find the fan sound suddenly increases when computationally intensive apps run, there is something wrong with it.    

How to prevent MacBook fan failure?

Before you reach the Apple support team, try implementing the following things to Fix MacBook Pro Fans Not Working.

Check active browsers & apps

Your MacBook Pro fan will create a loud noise if multiple browsers and applications are running at the same time. It can also make your MacBook overheat excessively by constantly running a fan at a higher speed.

Ensure vents are not blocked

The MacBook’s fan is responsible for throwing the warm air out and taking the fresh air inside. Blockage of any of the vents can make your system keep getting hotter. Vents are usually blocked when users put them on soft surfaces such as cushions or beds.

Hence, no matter which MacBook model you are using, ensure the vents are not clogged up. Place your laptop on a flat and hard surface, such as a desk.

Stop power consuming processes

Click Utilities and then open Activity Monitor. Click the %CPU column to sort the process list by highest first. Select the activity that is using a higher amount of CPU time, choose it, and tap X. Click Quit.

Disable flash in your browser

By default, Flash is now disabled in the Firefox browser. However, in Chrome, you can use the Flash control function to disable the Flash instances. You can still see Flash on a per-site basis as required.

Disabling Flash is significantly important because it is one of the main causes of GPU and CPU overload. It will eventually increase the MacBook Pro fan speed as it is extremely intensive on the hardware.

Accumulated dust and dirt can sometimes block the cooling vents. If you don’t clean it regularly, the dust goes inside the MacBook and clogs the fan. This sometimes leads to MacBook Pro fans problems and producing abnormal sounds.

So, open up your MacBook and clean the vents & fan properly. Remove the bottom panel with a small screwdriver. Or you can use a can of compressed air or a small piece of lint-free cloth for cleaning.
