I also have the Belkin and I believe the noise you refer to is the cooling fan.
To me the noise is minimal but that is a personal observation. I have a IBM 60GXP
installed in it and I can still here it so the fan isn't much of a problem. I did
a lot of research before buying the Belkin and didn't see a better choice.
