The new AcoustiPack™ EXTRA Foam Blocks pack contains 3 acoustic foam blocks. AcoustiPack EXTRA Foam Blocks can be used inside any vacant drive bays to help increase the absorption of unwanted sound energy. Once installed, the foam blocks also help to reduce the internal air volume inside your PC or server case, which in turn may improve airflow velocity and the cooling performance.
Acoustipack EXTRA blocks are made from professional-grade dense acoustic foam, which is certified UL94-HF1 fire rating. The foam is especially effective at absorbing sound at higher-frequency, such as hard drive whine, or high-pitch noise from motherboard components. The foam is black, and flexible enough to squeeze into empty 5 1/4″ or 3 1/2″ drive bays to pressure-fit.
