Dell Portable Systems Encountering Fan Noise and High Temperatures


Dell Portable Systems Encountering Fan Noise and High Temperatures



The following article contains information about Dell portable systems experiencing loud fan noise and high temperatures.


Fan Noise and High Temperatures

You may experience your portable system getting hotter than usual and the fan running at a high speed when running CPU intensive applications.

The systems specific to this behavior are:

Troubleshooting Steps

The system BIOS should be updated first, the latest BIOS can be found on the Dell Support Product Support Page:

  1. Select your system model.
  2. Select the "Operating System."
  3. Under "Category," select "BIOS."
  4. Download the latest system "BIOS" and save the file to your system.
  5. Double-click the BIOS setup file and follow the on-screen instructions to complete the installation process.
Warning: Dell recommends disconnecting any external devices like external hard disk drives, printers, and scanners before updating the BIOS.

Dell portables must have the battery that is installed and charged to at least 10% before you begin the BIOS update. Dell recommends connecting the system to AC power before proceeding with the update process.

To learn more about updating the BIOS on a Dell system, see the Dell knowledgebase article: Dell BIOS Updates


Once the system BIOS has been updated, run the system's built-in diagnostics (ePSA diagnostic) to verify if there are any hardware issues.

  • If the diagnostics fail, note any error code and message. Then contact Dell Technical Support.
  • If the diagnostics pass, try the steps below.


The next step would be to download and install the latest version of the Intel Dynamic Platform and Thermal Framework.

  1. Go to the Dell Support Product Support Page.
  2. Select your system model.
  3. Select the "Operating System."
  4. Under "Category," select "Chipset."
  5. Download the latest version of the "Intel Dynamic Platform and Thermal Framework" and save the file to your system.
  6. Double-click the Intel Dynamic Platform and Thermal Framework setup file and follow the on-screen instructions to complete the installation process.


Boot your system to Windows and open the SupportAssist program. If SupportAssist is not installed, it can be downloaded here.

  1. Go to the "Troubleshooting" tab and click "I want to check a specific piece of hardware."
  2. Click "CPU" under "CPU Devices."
  3. Select "CPU Stress Test" and click "Run Test" (Figure 1).

  4. Listen to the system fan for excessive noise and feel the system for excess heat.

Updating the system BIOS and Intel Dynamic Platform and Thermal Framework should help with fan noise and excess heat issues.

G-Series Portable Systems

Dell G-Series portable systems can install the Alienware Command Center application to further help troubleshoot fan noise and excess heat issues.

  1. Install the Alienware Command Center application.
  2. Open the Alienware Command Center application.
  3. Click "Thermal" at the "Active Default Theme" and set it to "Performance" (Figure 2).

  4. Restart the system.
  5. Once the system boots into Windows, open SupportAssist.
    • If SupportAssist is not installed, it can be downloaded here.
  6. Go to the "Troubleshooting" tab and click "I want to check a specific piece of hardware."
  7. Click "CPU" under "CPU Devices."
  8. Select "CPU Stress Test" and click "Run Test."

  9. Open the "Alienware Command Center" and go to the "Fusion" tab.
    Monitor the "CPU Frequency" for 5 minutes and ensure that it stays within the Performance Mode parameters below.
    CPU Type Base Frequency Cool Mode Performance Mode
    Intel Processor i9-9880H 2300 MHz 2300 MHz ~ 4500 MHz 2500 MHz ~ 4500 MHz
    Intel Processor i7-9750H 2600 MHz 2600 MHz ~ 4100 MHz 3000 MHz ~ 4100 MHz
    Intel Processor i7-8750H 2200 MHz 2200 MHz ~ 4100 MHz 2600 MHz ~ 4100 MHz
    Intel Processor i5-9300H 2400 MHz 2400 MHz ~ 4000 MHz 2800 MHz ~ 4000 MHz
    Intel Processor i5-8300H 2300 MHz 2300 MHz ~ 4000 MHz 2700 MHz ~ 4100 MHz

    Also, monitor the CPU temperature during the stress test.
    • The CPU peak temperature should be less than or equal to (≤) 100 ℃.
    • When under high stress, the computer's average temperature can be expected to be less than (≤) 100 ℃.
    Note: The CPU average temperature can be expected to reach 95 ℃ under cool mode for the Dell G5 5590, G7 7590, and G7 7790 models.

Note: When the computer is running at heavy load, it produces more heat, therefore it is normal for the fan to spin up and generate slightly more fan noise. Some models like the G-Series notebooks are fitted with dual fans (CPU fan & GPU fan) to cool the notebook faster. While the dual fan operate simultaneously, it will produce more fan noise. The computer is working as per design and there is NO hardware change required.
