Macbook M1 Pro Fans running constantly at near max capacity

I've had this laptop for over a year now with no issues. 64 gb, m1. Absolutely love this laptop.

Now all of a sudden, the fans start to spin at more 4k-5k RPMs (very, very loud). This happens immediately on login, when I have nothing running, etc.

I tried doing a clean install of Mac OS Ventura, Mac OS Sonoma. I have run diagnostics as well, nothing came up. However, I know this isn't normal behavior. I never heard the fans up until a few weeks ago. Even if I quit all my applications, the fans continue to go insane. The noise is so much I have to wear earphones just to focus on my work.

I have two of these laptops, one of them from my work. This is only happening on my personal laptop. So I know for a fact this is very, very not normal.

I'm okay with the fans running if I'm doing some heavy rendering work - but if all I have is a few firefox tabs open? That's unacceptable for such an expensive machine.

I went to the Apple Store twice (I have Apple Care). They're telling me this is normal behavior. I know it is NOT.

I've attached a screenshot of my Activity monitor and Macs Fan Control.

Has anyone run into this issue? How were you able to resolve? Apple Support has been very disappointing.
