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

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.
