I just succeeded getting our (previously extraordinary loud) sh205
silent.

I applied the following modifications to the thing:

- break out the grille (? hope I got the correct word from my
dictionary) that covers the fan. This inhibits the noise produced by the
air flowing through the grille.

- mount the fan as deep as possible (a few mm) in the box. Slightly
increases the effect of the above mod.

- fill the parts outside the shielding (to the right of the drive) with
Pritex or something similar do damp resonances in the box.

The amount of noise reduction of these steps is compareable to pressing
the quiet button of a NEC P6.

- I replaced the fan by a silent one.

Now our Mega ST is louder than the drive. I think I will have to get a
silent fan for the Mega, too. I think, the above modifications which I
made a few months earlier are still necessary since they attack
completly independent sources of the noise of the drive.
