Why do you need to turn off your chassis fan out of curiousity? A program like speedfan should work, but if the fans to noisy you might just consider replacing it with a quieter fan.

Pretty sure speedfan wil only monitor/slowdown fan connect to a sensor on the motherboard ,therefor the fan cant be one power directly from the power supply .
i have been using window for many years and have never seen any option in window to turn off fans ,
the computer bios does not monitor fan that are plugged into the power supply

from the above link
SpeedFan can find almost any hardware monitor chip connected to the 2-wire SMBus (System Management Bus (trademark belonging to SMIF, Inc.), a subset of the I2C protocol)
suppoerted sensors list .

That is true of any fan controller-there is no way to control a fan hooked directly to the psu.

some OEM models do have them on the motherboard, but they also sell fan controllers that fit in the rear expansion slots or in a 3.5 or 5.25 inch slot up front that allows you to control the fan manually.
