They are labeled 5900 RPM (different label than pictured) but they hot like 7200 RPM Rims, they're loud like 7200rpm drives and they report to SMART like 7200rpm drives. These are discs with 7200 rpm. In fact, they SMART report how (and physically look) HGST Ultrastar 7K4000 HUS724040ALA640 7200 RPM drives. I don't have cooling for 7200rpm drives.
