Dell recommends that you flash your system BIOS (see links in the table below). Each of these BIOS updates listed in the table below modifies the fan profile to help regulate GPU temperature fluctuations. Note: if you are already experiencing video-related issues like the bullet points above, updating the BIOS will not correct them. Dell will provide support for customers who have experienced GPU failure according to the terms of the system warranty. These BIOS updates will help reduce the likelihood of GPU issues. New systems are being shipped with the updated BIOS revisions.More info at Dell.
