Excellent service, informative website

Changing the fan on my old computer saved me from having to buy a new machine. Thanks, Quiet PC. Julian Kenny, 16th November 2015 (via Trustpilot)

Acousti APEXTB1 AcoustiPack 5.25

The AcoustiPack™ 5.25" Foam Block can be used inside any vacant optical drive bay to help increase the absorption of unwanted sound energy. Once installed, the foam block also helps to reduce the internal air volume inside your PC or server case, which in turn may improve airflow velocity and cooling performance.

The blocks are made from professional-grade dense acoustic foam, which is certified to UL94-HF1 fire rating. The foam is especially effective at absorbing sound at higher frequencies, such as HDD whine or high-pitched noise from oscillating motherboard components. The foam is black and flexible enough to perfectly friction-fit into any empty 5¼" drive bay.

A smaller 3.5" bay version and a three-piece kit is also available.
