Sorry for totally abandoning this thread, I added some extra thermal compound around the CPU and fixed the intel gpu drivers (for some reason it defaulted to the ancient/broken xorg intel drivers instead of the modesetting drivers) and I haven’t heard it ramp up since then.
These drivers were also contributing to a variety of graphics crashes on my end. Was it xorg-x11-drv-intel by any chance? Removed it and everything simply worked.
Yep, they’re the old broken ones. My issue was there was OTHER x11 configs in /usr which were calling for the Intel driver, so when I uninstalled them it was tty only until I figured it out.
