Laptop fan noise when booting or running

Update Time: 2023-06-30 11:51:20

Cause:

It is normal for the fan to make a sound when running. The fan speed is intelligently adjusted according to the machine loading to ensure better heat dissipation and noise experience. When running large programs (such as games, high-definition video, large audio and video, graphics editing software, etc.), the CPU occupancy rate is higher, and the fan will relatively increase the speed to dissipate heat for the machine, so the sound will naturally be slightly louder.



Solution:

Please follow the following troubleshooting steps one by one:

1. Whether the fan is noisy when booting:

  • The system may get updated automatically in the background when first booting so if the device is used for a long time, it will heat. The update will be done at one time and when it's completed, the fan wouldn't be noisy. 

  • Please check if your computer has too many startup programs or some demanding programs (such as large games, audio/video/graphics editing software, etc.) waiting to be started, which will lead to high system resource usage and startup fan running when booting. We suggest you right-click the desktop taskbar and open Task Manager > Startup to disable the uncommon applications.


2. Whether the fan noise when running:

  • There are programs running in the background that will occupy high CPU resources, resulting in faster fan speed and increased noise. We suggest you right-click the desktop taskbar and open "Task Manager > Applications or Processes > Rank by CPU Usage" to see what process is taking up a lot of CPU, if this process is not needed, please right-click to end this process.


  • Some programs running in the background will take up a lot of CPU resources, resulting in faster fan speed and increased noise. We suggest you right-click the desktop taskbar and open "Task Manager>Applications or Processes>Rank by CPU usage" to see what process is taking up a lot of CPU, if this process is not needed, please right-click to end this process.


If the above is not effective, we suggest you back up your data and bring the relevant documents to the nearest realme customer service center for testing.
