Acer Aspire 9813WKMI fan runs all the time after suspend to ram

Perhaps it would be worth experimenting instead with OSI when booting and see what happens then? e.g.
acpi_osi="!Windows 2006"
(Perhaps OSYS also triggers an SMI trap which does or doesn't do it? Worth a shot at least).
acpi_osi="!Windows 2006"
acpi_osi="!Windows 2001 SP2"
acpi_osi="!Windows 2001 SP1"
acpi_osi="!Windows 2001"
It is same with all. On cold boot fan stop ~1-2 seconds after Grub (Scope PR INI) and never stop after suspend.

Best you create a bug for that at bugzilla.kernel.org (and add me to CC or post the bug no).
Full (or none) fan is a real blocker bug that should generally be resolved.I've also had a report from a user the other day that hit the same bug on an Aspire 5710 series (which seems to have the same root cause, from glancing over the DSDT):

Does this BIOS expose an ACPI fan device correctly?
Acer BIOS's never expose the fan, AFAIK (and it's not available through WMI either).
Is this kernel bug or not?

Is the temperature ever updated after s3?
It seems that we have some similar bug reports for this problem. Please refer to bug
