Question : Problem: acoustic mode in the bios of s5000vsa

To use acoustic mode in the bios of s5000vsa do I need closed loop selected in the throttling mode? I currently have open loop selected.
Does it make a difference? My fan is driving me nuts and this is why I am adjusting. I have replaced 4 fans.

Fan control issues are often fixed in BIOS updates.
