The fan operates at a set speed until the inlet air temperature exceeds the lowerset point (see Table 1).
如果环境空气温度不超过最低设置温度，风扇一直以设定温度转动(见表1)。
2
Systems should be designed to provide air around the boxed processor fan heatsink that remains below the lowerset point.
系统应该设计为使盒装处理器风扇散热器周围空气温度保持在设定点的下限以下。
3
System integrators should design systems that ensure that the air temperature around the boxed processor fan heatsink is kept below the lowerset point for the lowest noise level.
