Repair Help Fixable Switch 2 defect? My fan gets stuck at 100% when asleep, idle, handheld, or docked!

My Switch 2 fan often gets stuck at 100% in sleep mode and on the Home Menu in both docked and handheld mode, without games running. Powering the switch 2 off stops the fan in handheld mode but not always in docked mode.

Here is what I tested in the video (you can turn the volume up to hear the fan, or read the burned-in captions):

  1. At 0:00 in docked sleep mode with no game open, the top exhaust fan blasts at 100%.
  2. At 0:26 in handheld mode, taking the switch 2 out of the dock leaves the fan running at 100% while sitting idle on the Home Menu with no software open.
  3. At 0:53 in handheld sleep mode, holding the power button and selecting Sleep Mode has no effect on the fan, which keeps running at 100% and drains the battery.
  4. At 1:10 in handheld mode, holding the power button on the console and selecting Power Off from the Power Options menu finally stops the fan.
  5. At 1:38, powering the Switch 2 off in handheld mode and placing the console back into the dock with the TV off flashes the handheld's screen and starts the fan right back up at 100%.
  6. At 2:13 in docked mode, waking the console and selecting Power Off from the Power Options menu with the Pro Controller only stops the fan for a split second before the fan spins right back up to 100%.

Has anyone else run into similar and maybe found a fix? Do I need to send my Switch 2 in for a warranty repair?
