Have you ever experienced an eMac fan noise that suddenly becomes louder? After a certain period, the MacBook’s battery drops quickly, and then the whole Mac computer becomes hot. If you look at the running applications in the dock, you will find that maybe safari and a few other applications are running normally.

Normally, there should be a running application process that is abnormal; this results in excessively high GPU or CPU on the eMac. However, some processes may occupy and use computer energy. In this case, we can use some cool apps like the activity monitor app, which can find and close. However, some processes may not be occupied continuously, and in this scenario, it requires long-term monitoring.

Additionally, disk read and write operations, maybe on a large amount of data, can also cause this issue, but it resumes normal operations after you end the operations. So, do we have a way in which we can deal with this problem? You do not have to worry. In this article, we will show you how to handle this eMac fan noise issue.

Tips on how to quickly fix eMac fan noise

1. Use activity monitor

Check the activity monitor (CPU), then sort running processes from %CPU column starting from high to low. The next step is to check if any of the application or service processes may be taking up much of the CPU. However, some of the processes may not be responding, and if you find so, close it. After that, choose the memory tab then sort the process starting high to low in the memory column.

2. Sync then download data from iCloud

At some point, there can be many photos and maybe other data that are syncing and downloading to the disk drive from the iCloud. In this case, there is connection instability with an apple server or a continuous network application and a disk data writing which can cause the eMac fan to work faster and produce higher noise. These are steps on how to do it;

  • Check the system preference
  • Identify Apple ID, then iCloud
  • Next, try to switch off the iCloud drive then turn it on at another point in time.
  • Switch off the iCloud drive on mac.

3. iPhone backup and time machine

If you backup your mac to a time machine with the external disk, it makes your computer stuck, and because of that, the fan often accelerates, more so when macs are using SATA and fusion hard drives. Therefore it’s better to connect the time machine disk backup on the two computers only during the hours that you are not working. It is good to click the time machine icon from the menu bar and see if it is working.

4. IPad and iPhone backup and sync

Similarly to the above two cases, when your iPad and iPhone are in connection with your eMac, then the mac might be synchronizing and at the same time have many photos be backed up by the process, music, and maybe other data on your iPad to the computer. After a while, it comes to an end, but it all depends on data in your iPad, iPhone, and also the capacity of the iPad or iPhone device. And you may be able to see the back process or sync in finder or iTunes in Catalina.

5. View the login service items

Normally when one views the items for login in system preferences, it is still hard to find any login items. However, some of the applications will open automatically when you start the mac, but many of the automatic login services will maybe not be displayed there. If you find that the activity monitor login process is consuming a lot of CPU, killing it may only work this time.

Additionally, after you start the computer, it runs again. At this point, we use the power suite to check all of the power login items, download and then install the power suite, then choose the startup boost tab. After that, it will display all the auto-login services and applications, and you can also click the switch button to remove them from the auto-login list.

6. Applications old auto-running 32-bit

If you are using macOS Catalina, it may not support the application of the old 32 bit. Might you be having application-related components or old 32-bit applications and plugins which probably are running on your computer? For instance, some of the programs may constantly need automatic upgrade checks. Sometimes I used to come across old Microsoft offices with auto-updates for a good period of time, and, unfortunately, this used to occupy 250% of my computer’s CPU. It uses the energy for the computer, resulting in Mac overheating and also fan acceleration.

It is very important to completely remove applications of old 32 bit and the related files in your macOS Catalina computer. After that, you can download and install the power suit, then choose the app uninstaller tab. It has the capability of scanning all applications on the mac, then using the option for sort- starting with 32bit to 64, all 32-bit applications will be displayed on your mac, choose them to delete files and applications related to the application.

7. The application takes up GPU

As far as I am aware, by default, the Google app can switch on hardware acceleration, and this can consume a lot of GPU when you use chrome and have many website pages open. This problem can be resolved if you switch off the acceleration hardware in chrome. To complete this,

  • Move to chrome preference
  • Choose the settings option
  • Go to advanced, then system
  • Finally, select the switch off option

Of great importance, note that you should use hardware acceleration only when available. However, if other applications may use that feature of hardware acceleration, try to switch it off.

8. Check your applications and tabs

The more applications and browser tabs you load, the higher the chance your eMac needs to use its fan to ensure that the system is kept cool. It is important to stop your multi-tasking by shutting programs, especially when using graphics-intensive tools such as Photo editing and iMovie. 

Ensure you open the Task Manager and select CPU to check which apps use most CPU resources. Chrome is more a resource consumer than Safari, in my experience, so you might attempt to swap your browsers for a better internet experience.
