Thank you for taking the time to provide us with your feedback. I am sorry to hear about your overheating issue. That can be very frustrating. Here are some tips to try to help your computer stay cooler,

It is essential to make sure that your computer is running the most up to date bios. You can check by using the link below.
BIOS is an acronym that stands for Basic Input Output System. Also known as " System Setup," the BIOS is embedded software on a small memory chip on the computer motherboard. This chip is referred to as the Complementary Metal Oxide Semiconductor (CMOS). It acts as an interface between the computer hardware and operating system, allowing the software to control the hardware.
The BIOS contains instructions that the computer uses to perform basic instructions, such booting from a network or hard drive or which drive to boot from.
BIOS is also used to identify and configure hardware components in a computer. These include the hard drive, floppy drive, optical drive, processor, memory, and Plug-and-Play devices. This is called the ESCD (Extended System Configuration Data) and is stored in additional non-volatile memory known as Non-Volatile Random Access Memory (NVRAM).
Over the years, as technology has changed, people still refer to the BIOS as both CMOS and NVRAM. However, they are subtly different. The CMOS contains the BIOS and its settings. The NVRAM contains the ESCD, thus updating the BIOS does not clear the NVRAM.

Dell recommends updating the BIOS as part of your scheduled update cycle. Like operating system and driver revisions, a BIOS update contains feature enhancements or changes that help keep your system software current and compatible with other system modules (hardware, firmware, drivers, and software) as well as providing security updates and increased stability.
Unlike Windows and anti-virus program updates, which are automatic, BIOS has to be updated manually.
Dell provides an easy-to-use self-installing update package.
The XPS 13 7390 BIOS update for fan performance was included in revision 1.3.1 – however, there is a more recent BIOS that contains critical security updates that should be used in place. https://dell.to/2yymQtX
