Dell Inspiron G5 15 5505 - Temperatures and suspend

sensors returns the following:

What is the difference between k10temp-pci-00c3 values and the CPU value of dell_smm-virtual-0? The former is usually much higher than the later under load (around +20c). Following the guide, I can use ryzenadj to set he maximum temperature which is read by k10temp-pci-00c3. However, the script to control fans use the CPU and GPU temperatures from dell_smm-virtual-0.

Next problem is suspending. I have enabled S3 sleep via a bios hack. The only way I can make it suspend to ram is to close the lid and then write "mem" to "/sys/power/state" via ssh. If the lid is open, it suspend and resume immediately. It does so under gnome or KDE. I have tried disabling all devices in "/proc/acpi/wakeup". When I do "systemctl suspend", I get an error "systemd-sleep[12894]: Failed to find location to hibernate to: Function not implemented".

My boot parameters:

root=LABEL=Roots rootflags=subvol=/roots/arch rw quiet splash selinux=0 amdgpu.runpm=0

dmesg | grep S3  
[    0.383216] ACPI: (supports S0 S3 S4 S5)

Power states:

cat /sys/power/state                
freeze mem disk

cat /sys/power/disk 
platform shutdown reboot [suspend] test_resume

cat /sys/power/mem_sleep 
s2idle [deep]

Systemd sleep.conf:

[Sleep]
SuspendMode=suspend
SuspendState=mem
HibernateMode=suspend
HibernateState=mem
