Symptoms experienced if the system is overheating:

Fans constantly run at high speed
Slow performance
The computer is too hot to touch
You can try these troubleshooting steps to reduce the overheating on your system:
Make sure the system is in a well-ventilated area
Use laptops on flat surfaces to improve airflow. Hard table tops are recommended and avoid using any type of cloth or any other soft material under the laptop
For desktop systems, make sure there is enough clearance around the system to allow the air to flow. If the system is in an enclosure, try to move it to a more ventilated area for testing
Check that the air vents are clean and that there is nothing obstructing them. See General Maintenance For Maintaining Your Dell Computer for instructions on how to clean your system
Update your system BIOS to the latest available in the Dell Support Site
You can reset your BIOS settings to undo any changes that could be causing the system to overheat. See How to restore the BIOS (System Setup) defaults on a Dell Product
