The fans installed in your Macbook help to cool down your laptop and bring it back to the optimal temperature so that the internal hardware components will not get damaged from overheating.
Often times, you’ll notice that your Macbook becomes hot especially when you’re performing heavy tasks or the processor is under high load. Under such circumstances, it’s important to let your Macbook cool and return to the normal temperature to prevent from any critical issues.
The design of the new Macbook models is in such a way that it keeps the fan inside the system silent. If your Macbook doesn’t cool down easily then one reason could be because the fan is not functioning properly. It can cause the system to get very hot on the front and back as well as on the hinges.
To find out whether the fan in your Macbook is damaged or not working properly, read the guide below.
How to Check If Your Macbook Fan Is Working Properly
Step 1: Launch Safari and head to CrystalIdea website.
Step 2: Download the Macs Fan Control software. Make sure to choose the Mac OS X version.
Step 3: Once the file is downloaded, unzip it and double click on its icon to launch the software.
Step 4: On the sidebar, you’ll see a list of all the fans that are installed in your system. There’s a column labelled Min/Current/Max RPM that shows the RPM values of each fan. The first value is the minimum speed your fan should be at, the second is the current speed and the last value is the maximum speed your fan should operate at.
Step 5: To find out what the current RPM of your fan is, check the middle value out of the three values shown. If the value is zero (as shown below) or below the minimum RPM then it means that your fan is not working properly. Otherwise, if the value is not zero and above the minimum RPM then it is functioning properly.
For some models of Mac, such as mine which is a 2014 Macbook Air, the system will safely turn off the fan when the CPU is running at low capacity. In this case, your fan still functions properly and will be turned on automatically by the system when appropriate.
If your system’s fan is damaged then the best option is to take it to a nearby Apple Store and have it repaired as soon as possible before it causes your Macbook to overheat and damage the internal hardware components. A temporary solution would be to keep the system air conditioned and close to an on-desk fan.
