EPIA ML-Series Operating Guide
Noise Level Data
VIA and the EPIA series have been at the forefront of the quiet computing initiative. The VIA EPIA ML-
Series has been designed to be totally non-obtrusive with noise levels equivalent to a person whispering.
With noise levels ranging from the totally silent VIA EPIA ML5000EA to 25dBA for the VIA EPIA ML8000A,
a new wave of system design innovation and exciting opportunities are being created in an almost
limitless number of emerging new market segments - ranging from fanless thin clients, flat panel small
form factor desktop replacement systems, LCD PCs and a host of other space and power saving systems.
