relatively quiet ... replacement for the older weaker source of sestravy the Lenovo IdeaCentre h535 where some kind vjetnam hauntkey or so ... but he was completely inaudible, but he had a 120W less power ... let's see if they can handle GTX750 not completely silent, but certainly not uncomfortably loud ... sort of fan sound normal over time.
