Used for a PC multimedia room, what I wanted was a silent priority and quality food. For quality, I trust the very positive test many sites unanimous on the subject. Apart from that the packaging and finishing of the object we are not questioning our purchase. For silence, then it's really impressive is ZERO decibels. Nada, nothing, zilch, one wonders if the PC is powered on. No hissing, no rattling, no irregular noise. Silence ... BE QUIET!
