CPU-5: The processor seems to be overheating causing the system to become instable

Article Number: CPU-5

​​The motherboard BIOS or system monitoring software reports extremely high CPU temperatures and the system is experiencing random crashes, shut downs, blue screen errors or other system instability.

When under a full or heavy load, a processor will often run hotter than when at idle or under a light load. Some degree of temperature increase is normal.  As long as the processor is under its maximum operating temperature it will function fine.

An abnormal processor temperature can be related to the use of an incompatible heatsink/fan combination (HSF), improper installation of the HSF, or incorrect airflow within the system case.

The following recommendations can help resolve the issue:

  1. Determine the temperature of the processor immediately after a system instability error occurs
    1. Check the reported processor temperature recorded in the BIOS
      1. For more information on how to view the processor temperature, refer to the motherboard manual or contact the manufacturer
    2. Compare the reported temperature against the maximum operating temperature of the processor
      1. To determine the maximum operating temperature of any AMD processor refer to AMD's Products Resource Center
    3. If the temperature of the processor is reporting under the maximum operating temperature, the processor may not be at fault or the motherboard BIOS is incorrectly measuring the processor's temperature

      If the processor temperature is not reading correctly, a BIOS update may be required

      If the processor is above its maximum operating temperature:​

      1. Ensure an AMD approved thermal solution is being used with the processor
        1. AMD Processor in a Box packages come complete with an AMD qualified HSF, which has been specially selected and paired with the supplied processor for optimum cooling
        2. If using a third party HSF, refer to AMD's System Building and Compatibility Info page to verify the compatibility of your HSF and AMD processor
      2. Ensure the HSF is properly installed
      3. Ensure a proper amount of thermal grease is installed between the HSF and processor
        1. The AMD Processor in a Box HSF unit comes pre-applied with the correct amount of thermal grease
      4. Improper installation of thermal grease can create a heat pocket between the processor and HSF unit.
      5. Ensure the bottom of the HSF is leveled on the top of the processor
      6. Ensure that the fan is connected correctly and that it is spinning when the system is powered on
      7. Verify that the airflow within the system case is circulating correctly
        1. Check whether there are any loose cables stopping the fan from spinning or blocking the air flow within the system case
          1. Check whether each case fan is pointed in the correct direction
          2. If all case fans are pulling air in the same direction, it can create an overpressure inside the case and cause the temperature to rise
          3. Air should flow in from the front of the case and out through the back of the case.
