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)
