做为硬件监控speedfan是一个免费软件，它不仅监测CPU风扇、机箱风扇的转速，还能从传感监测芯片知道CPU、芯片组、硬盘、工作电压等硬件环境。更为出色的是广泛的硬件支持。它主要的特征就是能够依照你的计算机内部环境情况控制风扇的转速，减少噪音和功耗。另外它也能查看S.M.A.R.T.硬盘安全数据（需硬盘支持）、 FSB调节等。就它的最基本功能，但我觉得已经够用了。 新版加入对nVidia nForce2芯片组的支持，及W83L785TS-S、ALi M1535D/D+等等。

v4.29更新内容：
added full support for AMD K8 (Sempron, Opteron, Athlon 64) internal temperature sensor
- added full support for Intel ICH8 SMBus
- added full support for NVIDIA MCP04
- events can now send EMAILs using the built-in multithreaded server
-SEND MAIL for events sends an email containing all current readings (temperatures, fans, fan speeds, voltages and hard disk status)
- implemented hysteresis in fan speeds control (this should greatly reduce fluctuations)
- optimized chart repainting
- fixed multiple instance detection of video cards
- added detection and support for new revisions of IT8712F
- added detection for some Analog Devices chips
- added support for hardware monitor at unusual addresses on W83627EHF
- identified some new Winbond W83627 revisions
- hard disk temperature is recomputed in the IN-DEPTH ONLINE REPORT
- fixed "error loading event" message at startup

买主板时有送中文版同类软件．

v4.29是8月3日刚刚更新的版本。

值得下载．

可惜我的主板不支持CPU的温度监控和风扇转速调整。还是支持一个。

SpeedFan v4.30 Final

更新内容：
