[Framework Desktop / Fedora 43] Fan spins during suspend

I’m running Fedora 43 on a Framework desktop and noticed that when I suspend the system, the fan will still spin up at times, which is quite annoying overnight!

Based on System Power Management Sleep States, it seems that only s2idle is available on my system:

$ cat /sys/power/mem_sleep
[s2idle]

Is there any specific guidance/limitation on which other states can be enabled on Framework desktop? Would appreciate any relevant user guide on this as well. Thanks!

You could use smokeless UMAF to enable [deep], no guarantee though.
