@Mr. Takashi Iwai, checked the Live system using cat /etc/fstab. Confirmed!
Live system is ext4. So, did a Leap-15.4 on ext4 install on SSD, too. Result
is, the 60���C idle temp issue is also present on ext4, it seems to be at least
as prevalent as in the btrfs case, i. e., I could not find one case in 5
reboots, where temperatures would cease to 45���C and the fan would move to level
0.

To conclude investigations on that ThinkPad W530 being used so far: the
Leap-15.4 ext4 Live System doesn't have it, but a Leap-15.4 on SSD - ext4 as
well as btrfs - does have the 60���C idle temp issue, no matter what.

That's it for now, thanks for reading,
