Scythe announced today three new sleeve bearing Ultra Kaze 120mm case fans. Unlike the common fans with 25mm thickness, the new Ultra Kaze 120 fans come with 38mm thikness. The slowest model (DFS123812L-1000) has the following specifications: 1000RPM, 19,81dBA and 44,44CFM. Furthermore, it is designed for silent operation in a PC system. Other models of Ultra Kaze 120 - DFS123812L-2000 and DFS123812H-3000 - aim for enthusiasts who are seeking high performance and high airflow for their PCs.
I just ordered this one so I'll see how it works.
