XPS 13 9300 running hot

Question

I have a relatively new (<6 months) Dell XPS 13 9300, which I've enjoyed until recently. About a month or so ago my computer inexplicably starting running very hot. Even when the computer is idling, it runs at about 150F--I can feel the heat on my fingers while I type. When I try to do anything, and when I boot the computer, it gets to the 190F range.

High computer temperature immediately after booting up my computer, with low CPU usageHigh temperature when my computer is idling

Things I've tried without success:

Running Dell SupportAssist and updating all drivers
Updating BIOS to the newest version
Updating Windows 10
Setting power mode to "best battery life"
Installing Dell Power Manager and setting the thermal management mode to "cool"
Using compressed air to clean the vents

The above images were taken after all of these steps were taken.
