This error indicates that a problem exists related to the heat removal system. One of two possible events is occurring:
The system fan is not spinning or not spinning properly.
The temperature inside the case is too high and the fan cannot spin fast enough to remove the heat.
To fix this error, use the following steps:
If you notice that the system fan spins and is blowing warm air from the computer, clean the exterior vents to remove dust buildup by blowing air through the vent openings. Do this while the computer is off. Dust can accumulate inside the vent opening and around internal cooling components, preventing the removal of heat. After dust has been removed, try turning on the computer to see if the error goes away. if not, continue to the next step.
Perform a hard reset. Performing a hard reset can reset recorded thermal values in memory and enable you to use the computer again — even if only for a short time to access and save any important files before service.
In some cases, updating the BIOS may help prevent this error from occurring.
Have the computer serviced to clean internal components and replace the system fan if necessary. Ensure that the following items are addressed during servicing:
Thoroughly remove dust from all internal cooling components.
Ensure that wires from the system and CPU fans are connected to the motherboard securely.
Ensure that the system fan blades spin correctly, and that the fan is not producing loud noises. If not working correctly, replace the system fan.
Remove old thermal compound from integrated circuits and heat sinks, and replace with new thermal compound.
