nvidia video card fan control

I replaced an nvidia 7600 GT with nvidia 9500 GT. I used nvclock to control fan rpm.
With 9500GT I tried nvidia-settings to change fan rpm, but I only am able to increase it from 40% and I can't get it lower than 40%. Maybe it's a security measure from nvidia.
The interesting thing, that nvclock shows the fan - duty cycle value the other way around. It is 40% but nvclock shows 60%. When I adjust the control to 80%, fan is more quiet, so it's on 20% in reality.

With the old card, this value was displayed correctly.

Is it possible to get lower fan rpm with nvidia-settings than the manufecturer's default?
What do you think the issue is with nvclock?

One more thing. If I have the fan slowed down with nvclock, nvidia-settings still displays 40% for the fan.

What do you think the issue is with nvclock?

Have you tried installing http://aur.archlinux.org/packages.php?ID=41012 to see if it behaves better with your video card?

Is there any difference between the one in community repo and the AUR one? It seems the same for me.

Okay, I installed the AUR package, but everything is the same.
