Framework AI 300 (HX 370) overly warm?

Hi folks!

I just upgraded by Framework 13, 7640u to the HX 370, and I’m suffering heat and battery life issues, including while idle. I know Ubuntu isn’t marked as supported yet, and I so I’m posting here to check and see if folks have experienced similar issues on Ubuntu 24.04.

Here’s my system details report from ubuntu’s settings.

What I’m seeing: with my 7640u, I would rarely have heat or battery issues on ubuntu in “balanced” mode, but the HX 370 seems to warm up even when the laptop is closed in power saver mode.

When active, but doing basic activities, the device seems to run the fan and get hot, despite the fact that the HTOP load isn’t too crazy, I believe in the 5-10% range, and most of the active processes are just gnome shell (when in use, not sure when idle).

Have other folks experienced similar issues of idle or light load battery / heat issues with this mainboard? (I have also used the 1240p, which this seems to run much hotter than when closed / idle as well)

Potential theory: It says “Software rendering” in the info above, shouldn’t it be hardware rendered? Is the problem that I have an older kernel (6.8) and therefore outdated drivers? I assume 25.04 would help, though the “upgrade path” to it is currently disabled due to that kubuntu issue.

Just an update on this in case anyone experiences the same thing:

I attempted to upgrade to 24.10, and the laptop then failed to boot, with the white-screen of death. I backed up and reformatted the laptop with the latest OS, and 25.04 is working great. Although the laptop is warmer than the 7640u, I expected that. I am not confident what the specific issue, but some combination of 25.04, the newer kernel, or a reformat fixed it. I believe the underlying issue was the desktop was rendering in software mode, which was pegging the CPU and therefore causing it to run very hot.
