Depends on what you consider quiet.
I would recommend the Scythe SFF21F and the SFF21E as quiet fans that push a decent amount of air. The Nexus D12SL-12 (also available as the Yate Loon D12SL-12) is another great fan, as is the Noctua NF-S12. All of them have a more-or-less silent noise profile at full speed and they push a reasonably good amount of air at this speed.
