Vornado Zippi totally silent. I was using it when I was keeping a tube amp in a rack with somewhat limited shelf space. I had the fan blowing upwards over the top of the amp so the heat would blow out the side of the rack and not heat the upper shelf too much. Worked perfectly.
Looking for Silent Fan Cooling f my ARC Tube AMP
I have my ARC tube amp in a corner. I like to stick a fan behind it . The one from radio shack worked great but made a little noise. Any suggestions . Thanks to all !
