The problem is not exclusive to just Macbooks. Regardless, when these issues get out of hand, it becomes almost impossible to use the Mac, especially if you need some peace and quiet to concentrate on a very important task.

If loud noises and overheating are something you have to deal with as well, this article ought to be of great use. Continue to read more of what is written here and find out what are the main causes behind the issues.

Cause #1 – Too many active apps

Overburdening the Macbook with too many active running apps causes a lot of problems, including overheating and loud noises from internal fans.

The system cannot process everything simultaneously. The toll can become overwhelming, so you need to be more conscious about the applications that are running in the background.

The Activity Monitor tool is great as you can sort the process by memory and CPU usage. Some applications like anti-virus are integral and ought to be running in the background at all times. However, you should be able to find ways to trim the list of active applications and save the resource of the system.

Cause #2 – Poorly optimised web browser

You may notice that the temperature and sound rise when you launch an internet browser. Meanwhile, doing anything else on the computer causes no problems.

Poorly optimised web browsers will consume a lot of memory and ask too much of the system. You may even find that finding a replacement is the best option. After all, there are multiple choices when it comes to internet browsers.

As for the optimisation itself, keep the number of open tabs to a minimum. Even when it is idle, a browser tab still consumes resources. Removing caches regularly and not installing too many extensions or add-ons will help maintain the browser in a better condition.

Cause #3 – Running of resource-heavy applications

Heavy resource consumers like video games are another example of how an application can make things worse. Some people would argue that Macbooks are not that great for gaming in the first place, and people who play video games on a Mac will continue to experience the problem.

If you love gaming, it would be better to purchase a console or even consider building a gaming computer.

Cause #4 – Accumulation of filth inside

Clean the dust and dirt inside the computer regularly. The task should be part of a maintenance routine. If you neglect it, do not be surprised to hear a loud noise or strong heat radiating from the Macbook.

There is an option to take the computer to a service store in case you are afraid of taking it apart yourself. You will have to pay money, but the expenses are well worth it.

Cause #5 – Poorly ventilated room

Poor ventilation only encourages the problem. If you have to use the Mac when it is summer, lack of air conditioner in the room will make it more or less impossible to accomplish anything while on the Macbook.

You might have heard about cooling pads. The accessory is great and will lessen the burden of the system, but you should still aim to focus on getting the room’s air circulation in order.

Cause #6 – Lack of disk space

Relatively small hard drives are one of the biggest disadvantages of Macbooks. Users struggle to keep every file on the computer. Trying to fit everything leaves very little storage space and leads to various issues.

You need to free up disk space. Start with removing junk files like caches and temporary backups. Deleting old applications, downloads, and email attachments will also help.

Finally, transfer some of your data to external storage devices and clouds.

Cause #7 – Viruses and malware

There are all kinds of cybersecurity threats, such as viruses, malware, trojans, or ransomware. The list continues to grow.

Many users probably think of malware and viruses as a means to gain and use personal information. But you may encounter some that strains the system by making it mismanage the resource usage. It escalates the temperature and leads to overworking internal fans.

Scan your system for threats and remove them. Also, make sure that a reliable anti-malware tool is always running in the background.

Cause #8 – Cluttered desktop

The habit of keeping everything on the computer’s desktop is not good. Each icon consumes resources, and the more files you have on the desktop, the worse off you are.

Keeping things organised will do wonders for the overall performance of the Macbook. Transfer the files to proper locations, and you will notice the difference immediately.
