FEATURES AND SPECIFICATIONS
Thermal Acoustic Products
Silent Drive is a thermal and acoustic enclosure designed to reduce the noise of a hard drive by more than 90% while still
SilentDrive™
maintaining the drive’s required ambient operating temperatures. A dense acoustical barrier and a thin decoupling foam line the
inside of the enclosure and prevent the transmission of noise outside the enclosure. Thermally conductive cold plates transfer the
heat generated by the hard drive inside SilentDrive’s enclosure to the ambient air within the PC chassis. SilentDrive can be
installed as original equipment by PC manufacturers or retrofitted into existing PCs by end users.
For reference, the typical noise level in a quiet room is 28 dBA. The noisiest of hard drives, in the 36 to 38 dBA range, will be
quieted to just below 30 dBA while others will be quieted to 28 dBA or less. (Note that a 3dBA reduction equates to a 50%
reduction in noise.)
Features and Benefits
s Silences hard drive noise. The hard drive emits noise
generally between 1 and 2 kHz, the most sensitive range
of the human ear. Eliminating this noise with SilentDrive
allows PCs to be used as a 24 hour appliance without
intruding into the user’s environment.
s High consumer acceptance
s Maintains drive operating specifications. Thermally
conductive aluminum plates ensure that the hard drive’s
operating temperature requirements are met, with no
degradation in performance, under elevated temperature
and load conditions in a host PC.
s No performance degradation
s SilentDrive installs easily into any standard 133.35mm
(5.25") bay of a PC. The product comes complete with all
required mounting hardware
s Easy assembly into PC chassis
