Tiny Cooling Fan is how to control the wind speed?

First choice "Tiny Cooling Fan" must be able to provide sufficient amount of exhaust (speed), under the high temperatures of the hot air inside the cooling device; when the temperature is relatively low and less when hot air is to do the opposite the work. Secondly, the position sensors installed option should pay attention to "Tiny Cooling Fan" sensor in the proper position, try to make the sensor can be directly clamped surface to be cooled. In the cooling fan is running, a temperature-controlled cooling fan will run at a faster pace if the thermistor feel higher temperatures; and at lower temperatures, it will operate at low speed; in these higher and intermediate low, "Tiny Cooling Fan" will hardly speed due to temperature change.
