Are these setting accurate:

wall power reference(W)     hashrate(GHS)         comment
400                                  800                       echo mode
570                                  1000                       normal mode
950                                  1300                       turbo mode

Assuming they are.  I can run 2 Avalon 4.1s using my Corsair ax1200i power supply at normal mode.   Is that right?

On Normal mode what is the dB at default settings?

Also for reference, what is the dB on turbo mode?

I will be putting these in my office so i want to make sure they are quiet
