    Single vs. Double Ball Bearing Case Fan: Which is Noiser?

    I am aware that double ball bearing (or dual ball bearing) case fans last longer than single ball bearing case fans.

    However, I am finding conflict report on the NOISE levels of these fans. Some say that DBB is noiser than regular fans; others say that DBB is quieter.

    Which is true? Can you link to an external reference as well so I can read up on this more.

    Also, for the Antec TriCool 120mm (regular not DBB type). Is this a single ball bearing or sleeve bearing type (the website is coy about disclosing this; only the DBB says it is ball bearing)?
