I got about 6 VERY LOUD fans going in my case, including 2 deltas (38 cfm ones). Is there a way to silence them? I've heard of people using Dynamat sound deadening stuff. Does this work? Mostly the noise is the air movement since of the deltas, two 120 mm going @ 108 cfm, 1 60 mm fan going @ 38 cfm and a 80 mm fan going @ 50 cfm. It's sooo loud I can't even hear the phone ring.
