Hello. I've just bought 7520 model with Ubuntu aboard also and seems  have the same problem (irritating fan noise even during idle or minimal usage).

Hardware diagnostics was passed successfully, but I have 4500-4600 RPM whole the time, even just after the power on.

CPU Therm sensor in idle shows 60 C, 76 C was the highest value during PSA tests.

BIOS version is A09

Hi SergiiR,

I would suggest you to update the BIOS on the system to A10 version using the link below which should fix the issue.

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.
