⑴SpeedFan是一个免费但功能强大的硬件监控工具，除了常见的CPU温度硬盘温度及风扇转速监测外，笔记本风扇控制软件SpeedFan还具有调节风扇转速的功能（包括手动调节和自动调节，并且可以对CPU进行软超频（原理类似CPUFSB和ClockGen。个人感觉其“图表”功能很实用，可以让我们通过不断变化的曲线直观地了解到CPU温度硬盘温度及风扇转速的总体走势。SpeedFan用在超频时监测CPU温度及风扇转速变化情况很适合，当然也可以用它来监测一下如今很火的Prescott核心赛扬D处理器，看看其待机温度和满负荷运行温度到底如何。 当然，大多数主板都有其厂家推出的专用监控软件，不过，将SpeedFan作为辅助软件来使用也是不错的选择（特别是那些杂牌主板需要注意的一点是，其监测出的各项数据与MotherBoard Monitor和Hardware Sensors Monitor一致，但与个别主板专用监测软件监测出的数据有少许出入（可能与主板使用的BIOS版本有关。
