RE: Dell Insprion 7520 high Intel PCH temp and high RPM of CPU fan

I decided to don't take a risk updating bios. A had a strange situation next day (the second day from the buying) - the temperature environment was the same, but the fun system behavior changed - became more adequate   - it looks like a car engine break-in - you have to pass some distance to make engine details fitted . Yes, I still have noise fan system sometimes, but now it can turn fans on and off depending on system load. Also I had Ubuntu updated to 12.10 before - not sure, but may be something changed with it also.
