QUIET QUIET QUIET! What else can I say? The pump is so quiet I can't even hear it from a few inches away. Same goes for the dual 120mm fans. Just a few feet away and they're quiet even on 12volts. Imagine what the results would sound like if a fan controller was used. I wish I could say the same for my hard drives
