ACPI does not control the fans on the Acer 5315.
There are no active cooling trip points under
the _TZ/_TZ01 -- the only ACPI thermal zone on the system.
And there are no PNP0C0B fan devices.
Re: the temperature reported by the ACPI thermal zone:
Method (_TMP, 0, Serialized)
{
If (ECON)
{
If (DTSE)
{
Store (DTS2, Local1)
If (LGreaterEqual (DTS1, DTS2))
{
Store (DTS1, Local1)
}
Store (Local1, \_SB.PCI0.LPC.EC0.SKTA)
Return (Add (0x0AAC, Multiply (Local1, 0x0A)))
}
}
Return (0x0BB8)
}
if (!ECON) you would get a constant reading:
0xBB8 = 3000 -> 300.0K -> 27C
Hmmm, but you're seeing 55C after resume -- is that always
true no matter what temperature was upon suspend?
also, if !ECON, a lot of things in the DSDT would go away....
eg. does /proc/acpi/battery/*/* still make sense after resume?
Perhaps you are open to some debugging with a modified DSDT?

Might be non-trivial, because past experience suggests
that nobody at Acer has ever run their ASL through
http://linuxfirmwarekit.org/ etc.
but first, perhaps you can poke some easy to turn knobs.
any difference booting with
acpi_osi=
or
acpi_osi="!Windows 2006"
(this may effect other things, such as HPET, or video display events)
BTW, here is yet another platform-specific item in this system
that Linux doesn't know about:
Device (MIR)
{
Name (_HID, EisaId ("ENE0100"))
I have no idea what it is, but in Windows you'll see this device
on IRQ 4.
