Okay, I bought a textorm 18 dba 12cm fan for my blowhole but saddly it's still too loud!!! Any way to quiten it? The hole it's blowing through is not round so can that make extra noise? It's sorta annoying... Or should I buy a muskateer and then regulate that 1 fan... But then, for the VU meter, can I still use my 5.1 audio or no? Help?
