How to Solve Fan Noise?

Article ID Code：GK-FAN-01

During device operation, the fan within the cooling module is the primary source of noise. Typically, GEEKOM conducts noise tests before the device leaves the factory to ensure the machine does not generate excessive noise under normal usage. However, certain factors may cause abnormal rotation speeds of the cooling fan or lead to it emitting sharp sounds.

Symptom

A.High CPU Temperature Causing High Fan Speed

Verification Method：Use monitoring software (such as HWMonitor, Core Temp, or MSI Afterburner) to observe the CPU temperature (normal idle <50°C, high load <85°C). If the noise increases in sync with the temperature rise and there are no other abnormal sounds, it is a normal thermal response.

B.Incorrect Fan Speed Policy 

Abnormal high-speed noise caused by incorrect fan speed settings. Regardless of the level of hardware resource usage, the cooling fan consistently maintains a high rotation speed.

Verification Method：Open Task Manager and check if the hardware resource usage (CPU/Memory/GPU) is consistently below 10%. Observe whether the fan continues to maintain a high speed during this time.

Software Faults

• Fan Control Software（General）

  • The software forcibly limits the fan speed percentage and runs within the Windows system.

  • 

• BIOS Fan Settings（General）

  • Change the machine's operating mode in the BIOS.Referring to this Video:https://support.geekompc.com_quietmode
  • Step 1: When powering on or restarting, repeatedly press the Del/Delete key to enter the BIOS menu.
  • Step 2: After entering the BIOS menu, navigate to the Advanced tab, look for the PowerMode option, and change it to QuietMode. Then press F4 to save the settings. The machine will automatically restart to apply the configuration. If this option is not available under the Advanced tab, you can find it under the Main tab. If the option is not present, adjust the FanMode instead.

    If this operation is ineffective, it is recommended to update to the latest EC firmware for the corresponding model, which can reset and optimize the current thermal management strategy.Referring to this tutoria：https://service.geekompc.com/faq/update-bios-ec/

• Model:IT15

  • Update the thermal fan control strategy to optimize cooling performance at the fundamental level.

Optimizing Heat Dissipation Methods

1. Optimize system load: Close background programs (end high-usage processes via Task Manager).
2. Improve ventilation: Ensure the ventilation ports on the bottom/sides of the computer are not blocked, and use it on a flat surface.
3. Long-term maintenance:  
   If the device is used intensively in a dusty environment, it is recommended to clean the dust every 6 months.  
   For normal usage in a standard indoor office environment, cleaning every 12 months is sufficient.  
   (Use a soft brush to remove dust or a can of compressed air to blow out the vents.)
