MacBook Overheating Fix: Quick Solutions Before It’s Too Late

Ever heard your MacBook sound like a jet plane or get hot? You aren't alone. Even with the complex cooling systems inside every MacBook, they still tend to overheat when used during long working sessions, gaming, or editing videos.

Overheating is also not just annoying. It can slow down the MacBook, or even worse, make it shut down. This issue is leading to considerable damage to the battery and internal components. The good news, though, is that most overheating issues can be fixed and resolved relatively easily when acted upon quickly.

Common Causes of MacBook Overheating

Let's discuss the most common causes, the most common and quick-resolving ways to tackle the overheating issues, along with important ways to make your MacBook run cool and quiet.

1. Dust Buildup

Dust Buildup is the one thing that can be annoying to any electronic. Over the years, the Dust that can be collected inside a MacBook, the ventilation, and the fans. Dust covers components of the systems or blocks components, and that is when temperature can increase to high levels quickly.

2. Too Many Background Apps

MacBooks are multitasking beasts. But, like any great multitasker, there are limits. Due to multiple tabs, Spotify, Photoshop, and some background updates, MacBook fans can get hot.

Every open app takes a space of your system’s power. The more it’s pushed, the more heat it generates. That constant strain is what makes your MacBook hot and sluggish.

3. Blocked Air Vents

A MacBook pulls in cool air through vents and expels hot air through some of the MacBook’s vents. Some vents are blocked when the MacBook is being used on soft surfaces. The vents work best when the MacBook is placed on a hard, flat surface, such as a desk or table.

4. High CPU Usage

Even if an app is not in use, programs running in the background can increase CPU usage and, in turn, cause overheating. Background processes, cloud syncing tools, and Chrome extensions can fire up the CPU, out of your focal range.

If the CPU is set to maximum functioning, uneven fans can be under pressure and thus spin faster for cooling. This is the moment you hear the noise of the fan.

5. Old or Worn-Out Battery

With age, a MacBook can reach a point of near deterioration, where the MacBook Battery starts to age and, in turn, degrade. A failing battery generates excessive heat while holding a charge. In rare instances, a battery can swell, and these instances require immediate attention.

6. Outdated Software

Using an outdated version of Mac software, or macOS in particular, can be a factor in bug formation in the processor. Problems with excessive battery consumption and system stress in the functioning of the processor or system are fixed in the updates, so always remember to assess the system.

How To Fix an Overheating MacBook

In this section, you will find the quickest tips to cool down your MacBook without calling a technician.

1. Quit Unused Applications and Browser Windows

Having multiple apps open simultaneously increases the amount of CPU and RAM the computer uses, and the overall workload increases.

Here’s a suggestion:

  • Hit Command + Q to quit apps that you’re not using.
  • In Safari and Chrome, getting rid of some open tabs will help.
  • These tabs do not do anything and still consume memory, which in turn, slows the computer down.
  • Note that you will likely get better results on a Mac with Safari than with Chrome in regard to battery life.

This simple step alone can cool down the MacBook’s temperature by several degrees.

2. Find and Shut Down Resource-Intensive Apps

There may be a single app that could be the sole reason behind the MacBook's overheating.

Here’s how you can find the problem:

  • Go to Activity Monitor (Applications → Utilities).
  • Select the CPU section.
  • Sort by % CPU to see which apps are the biggest power hogs.
  • Highlight the unnecessary processes and hit the Uninstall (X) option.

If you see an unknown app with a large CPU usage, the task is not in the scope of the problem, and is just the Mac managing temperature. But if you see an app like Photoshop or Google Chrome Helper and they are used a lot, they can be updated as required.

3. Use Clean and Clear Vents and Fans

The MacBook needs to be clean for it to work efficiently. Dust settles in as much as you try to avoid it.

Try this -

  • Turn off the MacBook.
  • A can of compressed air with short bursts can be used to clearly remove the dust that settles inside the vents.
  • Never use a vacuum, as it can generate static and damage components.
  • If you are confident that your Mac is out of warranty, you can open the MacBook’s bottom to clean the fans inside. Otherwise, an Apple technician can clean it for you.

4. Use Your MacBook on a Hard, Flat Surface

Sometimes, it is the simplest of things that matter the most.

  • Soft surfaces trap heat and block the laptop’s ventilation.
  • The laptop works best on desks or tables, while enhanced air circulation can be achieved with a cooling stand or a metal riser.
  • Placing a thin book under the rear of the laptop also aids circulation and can be very helpful.

5. Update macOS and Your Apps

Updating your apps is important. They can be valuable in offloading the CPU and improving the management of the fans.
