Note that that is a symbolic link to /etc/frontview/sensors/ULTRA66.conf (in your case for an Ultra6). 

Did you mean ULTRA6.conf ????

The problem with replacing the fan with another brand is that the "stall speed" may be higher, which sounds like your problem.  Your fan's minimum speed is higher than the stock one.  The fan comes on faster at power-on, and then gets trimmed to the necessary speed to maintain the desired temperature.  But the OS is trying to trim your fan to something below it's minimum.

 

sebcbien31: My Pro 6 doesn't have this issue.  The mininum fan speed (fan3_min) is set to 600 in my system.conf file, it appears to be set to 400 in yours.  One review I've seen says the minimum speed for your Noctua is 450 rpm.  

 

I'd probably just increase fan3_min to 600, but you could try 450 first, and see if that is enough.

Thanks Sandshark
I meant that it seemed that few hours after disk spun down, the system fan fall to 0 rpm.
I will try to edit system.conf as you suggested
