A noisy fan can indicate several things about your MacBook, but one thing always happens: your MacBook is overheating. This could be because the fan isn't doing its job, or it could be because of your software. Below are 5 tips to help you deal with fan noise on your Mac.
1. Dusty old fans
One reason MacBook fans work overtime is that they don't work efficiently. Over time, pet hair, dust, and millions of other potential contaminants find their way into the MacBook case.All of this debris can accumulate around the fan and other areas of the MacBook, meaning the fan's airflow or effective rotation is restricted.
Using a YouTube tutorial, you can unscrew the back of your MacBook and remove it for cleaning. You want to make sure you're not violating any warranty agreements, and you can even hire a computer repair shop to do that for you. The most important thing, however, is to be proactive and not reactive: make cleaning routine (i.e., execute a cleaning procedure). once every two months) to keep it in good condition. This is one of the most important steps to ensure the long life of your MacBook.
2. Airflow
Dirt inside the case isn't the only cause of poor airflow. Airflow may be restricted due to the placement of your MacBook. On the bed, it's a common cause of noisy fans, plus it's usually placed in a tight space with poor airflow. Make sure your MacBook is always placed on a hard, level surface so its feet can do their job. If not, you can use a laptop stand to elevate the device higher for better circulation.
3. Energy Resources
Your MacBook may overheat due to problems with the processor. The processor may be working very hard because many programs are running at the same time or the memory is full. Then go to Activity Monitor (tap "Apps" then "Utilities") and open the "CPU" tab to see what's running in the background. Tap the X to close unnecessary background apps and make sure you have enough free memory.
4. Reset SMC
The System Management Controller (SMC) is the driver responsible for most of the hardware in your MacBook, including the fans and processor.So if there is a problem with the SMC, the CPU and/or fans may be affected. Here's how to reset the SMC.
5. Disk Space
Your startup disk/hard disk may be almost full, which can cause your MacBook to slow down and overheat. Check the remaining disk space by accessing the memory settings and deleting programs, caches and logs that you no longer need. Some third-party apps can clean those congested but unnecessary junk files and background processes.If the problem isn't with the hardware, a general clean-up might assist keep the computer cool.
