Found out by experimenting:
One can set
configure->advanced->ADT7490->pwm3 to manual
And then pwm3 setting controls the memory fan.
Since I have stable load I turned off auto control and tuned for low noise while keeping an eye on temperatures.
I can shut memory fan down, I chose to leave it at 10% (~300 rpm, which the program displays as fan 2 I believe). This was almost all my noise.
The second "pwn1" for me is the only cpu fan I have, I pegged that also. The cpu fan may need changing at some point, it seems that will take more work.
I had to repeat some of the settings after a reboot, I dont have to keep speedfan running otherwise with pegged values. Reboots are rare for me.
In summary Any's guide gave me a quiet stable setup, thank you!!
