I'm wondering, why acerhdf is even loaded for your notebook, as no
MODULE_ALIAS matches:

[...]
MODULE_ALIAS("dmi:*:*Acer*:pnAOA*:");
MODULE_ALIAS("dmi:*:*Acer*:pnAspire 1410*:");
MODULE_ALIAS("dmi:*:*Acer*:pnAspire 1810*:");
MODULE_ALIAS("dmi:*:*Acer*:pnAO531*:");
[...]

Which distribution do you use? Does the distribution somehow autoload acerhdf? Or do you manually load the driver?

Boris, I agree, we really should check the cpu specs. A quick search got me to this page: http://www.hardwaresecrets.com/article/Maximum-CPU-Temperature/143/5 where we clearly see, that the core 2 have much lower critical temperatures.
I added all those 1410* and 1810T* entries on behalf of people telling they'd have the fan control working with these lines for some weeks without problems and I didn't care about searching for the netbooks specifications. My fault.

I would propose to enhance the bios_tbl by the default temperatures. What do you think?

thanks and kind regards,
