Kernel log

I have Gigabyte GTX 560 Ti Ultra Durable (01:00.0 VGA compatible controller:
NVIDIA Corporation GF114 [GeForce GTX 560 Ti] (rev a1)) and Nouveau doesn't
report correct fan speed. Reported value is exactly twice the actual speed.=

When I follow Documentation/thermal/nouveau_thermal and the speed to 100%,
nouveau reports "fan1: 6840 RPM" while the highest reported RPM b=
y Windows
(both Gigabyte tools and CPU-Z) is 3390 or 3420 RPM. Similar to when I set =
the
lowest speed (I have modified bios and my pwm1_min is 30) nouveau reports
"fan1: 3180 RPM" while Windows shows 1560 or 1590 RPM.
Could that be because the card has two physical fans? Reporting the speed of
single fan would make more sense IMHO.
