Review on 🎧 Black 2-Piece Sound Dampening Acoustic EP0M Silent Foam SF01 - 21"x15", 4mm Thickness - from Silverstone by Andrew Young

I used this on a NZXT Phantom 410 PC case. I have previously swapped out the fans for quieter ones but it didn't help with the vibrations that bothered me . What worked was to cut them into half inch strips and glue them where the front and top plastic panels snap together. Voila - no vibration. The plastic parts on the housing were to blame. Since this product contains two large sheets, I also made a side piece (one without the glass) and I have almost a whole sheet left. The fact is that if you want to insulate both sides, two panels is more than enough.
