My computer was so loud I'd have to turn it off to talk on the phone. I had recently got an Addtronics full-tower (very similar to the Supermicro--in fact, the lady at Addtronics says that they manufacture the Supermicro cases). I set it up with two fans blowing inwards from the front bezel, and one blowing out through a vent at the top front of the side panel next to the external disk bays.
I had seen a comment on one of the cooling sites about fans being noisy on account of the "vacuum cleaner" effect: If they are mounted too close to a wall. I experimented a little and found that by themselves the fans are almost silent.
Now I have two fans sitting on top of my vid card blowing directly at the cpu and memory -- noiselessly, as they aren't up against anything.
The drawback to this is that they don't directly pull air into the case. The way to remedy this without sacrificing decibels would be to mount the fans in a box with enough recess that it doesn't generate noise, and run tunnels from the box to the case for intake.
I saw something like this in a couple of places, I think the Intel site was one, except the tunnel takes the air directly from a case-mounted fan to the cpu, which wouldn't cut down on noise.
Next step is to figure out how to build the box, tunnel, and provide an opening in the case for air to come in.
Also could probably use something similar in the upper chamber for the exhaust side as I only have the power supply fan blowing in that direction.
