Digging further more, the issue, which is "new" (probably after having
switched to stretch?), is:
* in the BIOS or with kernel acpi=off
  The fan runs and runs well (at least, enough to avoid overheating)
* without this parameter the fan does not run (enough?) to avoid
  overheating (encoding a 2 minutes video => hard poweroff)


$ grep -h ^options /etc/modprobe.d/*
options snd_hda_intel index=1
options rtl8723be debug=1 swenc=0 ips=1 fwlps=0 msi=1 disable_watchdog=1
options radeon hw_i2c=1


$ cat /proc/cmdline 
BOOT_IMAGE=/vmlinuz-4.9.0-3-amd64 root=/dev/mapper/xxx ro radeon.dpm=1 cgroup_enable=memory apparmor=1 security=apparmor


$ lsmod|egrep 'think|fan|therm|temp'
