Sapphire HD 7850 2GB fans RPM on auto at idle - experiences?

[torro]

After about first 120 hours of nice and silent fan operation at 1150-1250 RPM on auto during low to moderate GPU 2D load producing really low temperatures (27-33°C), my brand new Sapphire non-OC HD 7850 (SKU 11200-07-...) switched to permanent loud 1800-1900 RPM on auto even at idle and right from a cold boot (20°C) -- most likely, due to the fan controller acoustic enhancement mode hardware logic failure.

Contacted Sapphire support to no avail (they even had a nerve to state that "the fan is impossible to run at 1100-1200RPM"), so as a last resort, I would really appreciate Sapphire HD 7850 owners GPU-Z screenshots showing fan speed percentage and RPM on auto at idle and, say, up to 40-45°C.

MTIA!
