I had Ubuntu 11.04 on my Acer 1410, and everything was working smoothly. I made a fresh installation of 12.04. Now the fan works heavily (noisy) all the time, even when no software is open. Here is the result of sensors command:

Adapter: ISA adapter
Core 0:       +30.0°C  (high = +105.0°C, crit = +105.0°C)

Adapter: Virtual device
temp1:        +55.0°C  (crit = +63.0°C)

I think the problem should be associated with drivers, but why on Ubuntu 12.04, and how to update drivers properly?
