We don't have any sound measurement equipment in the labs, but subjectively, it's safe to say that this board is very quiet. The supplied CPU cooler is a low profile unit and it doesn't even have a copper insert which is common place on pretty much all CPU coolers these days. The fan operates at a very low speed and you can control this further in the BIOS - AOpen's SilentTek options give you far more advanced controls over the fan speeds than you would find on most other motherboards.
