Can I use acoustic materials directly against hard disks, or to help with vibrational noise from hard disk drives?
: We would NOT recommend using any of our acoustic materials directly against hard disc drives (HDDs) as a method for vibrational noise dampening (although it is quite effective!), as these components normally require cool air circulation around them or good contact with metal for direct heat transfer. Acoustic foam is a thermal insulator, and as such is not recommended due to the potential for overheating to occur. HDD airborne noise is perhaps better attenuated using a product like the SilentDrive or an alternative disc enclosure. Of course, the best solution to HDD noise is to obtain a low-noise disk – such as the Seagate Barracuda IV or V. Other manufacturers like Samsung (SpinPoint) and Western Digital are also now producing fairly quiet hard disk drives. HDD vibrational noise can be attenuated by mounting a HDD using rubber grommets – these are already available pre-installed in some PC cases (for example, Antec Sonata and the AcoustiCase C6607).
