What's the best way to minimize noise on a current mining rig? I've been considering a few options:

-Lower the fan speed of the graphics card
-Put a water block on the graphics card
-Get a fanless graphics card (one that only has a heatsink)
-Use a special cooler (such as Accelero)
-Use sound dampening strips (such as Dynamat)

Any suggestions on how to make a current rig less noisy or tips on building a new, quieter rig would be greatly appreciated.
