Is there any software that can tell you the speed of the cpu fan, the temperature of the cpu, and also speed the cpu fan up to its maximum possible speed (100%)?

Usually your motherboard comes with software to do that sort of thing. However, if you bought a prebuilt computer, they usually dont have the sensors and controllers to do that.

-C

Use MotherBoardMonitor 5 (Google it, it's free)

When you set it up just choose your mobo make and model and it will do all the rest pretty much. Then it will tell you your CPU and Case temps in the system tray all the time. Plus it will tell you the fan speed of all fans connected to the mobo.

There is another wonderful freeware Called SpeedFan,

Apart form monitoring cpu fan speed it also shows hard disks temperatures too.
