Why is my headset showing a cooling fan issue notification?

I followed the steps above, including rebooting and performing a factory reset, but I still encounter the notification:

"SYSTEM ALERT
The cooling fan on your device is not functioning properly. Your headset may become warm or behave abnormally.
Please try rebooting. If the issue persists, contact customer support: https://meta.com/help/support/"

I tested the device and the fan is still working, but the headset only lasts 20 minutes before turning off. I would appreciate any support, as I am considering repairing the mainboard, though I don't have experience with this product.
