The Enermax TB Silence range is extremely impressive, the 120mm unit in particular is the quiet fan. The BatWing blades on the TB Silence 120mm are clearly not just a gimmicky name designed to attract geeky sci fi fanatics. The TB Silence 140mm is another great performer, with very low levels of noise meaning it is inaudible unless your ear is a few inches away from it. When you consider the airflow is also 77cfm then Enermax are onto another winner. They have earned a position as excellent products. For their and overall quality, they earn the Bjorn3D Silver Bear Award.
