Hmm, acerhdf is a driver for, originally, acer aspire one netbooks with
noisy fans. We have static limits which turn on the fan at 63 °C and
off again when the temperature reaches 58 °C - those are at least the
defaults.

Now you have a Core 2 Duo U9400 for which I can't find the specs after a
quick search but it looks like something a little bit more powerful than
a netbook cpu but still ultra low power. So, before we dig further into
this, is your fan noisy at all?

Peter, it looks like we support not only Atoms with that driver. Maybe
we should check the cpu specs of the 1810T for example (and google says
there are several different cpu types packaged with those laptops)
before we enforce temperature limits on them...? And let me ask you
this: are all those 1810T* entries in the bios_tbl there because of
noisy fans ...?

Thanks.
