Tiny Cooling Fan selection and installation considerations

First, the choice of "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 hot air when it is to do the opposite work. Secondly, the "Tiny Cooling Fan" to select the location of the sensor installation should pay attention to the sensor in the proper position, try to make the sensor directly clamped surface to be cooled. In operation, a temperature-controlled fan will operate at a faster rate if the thermistors sense higher temperatures; and at lower temperatures, will operate at a lower speed; at these higher and lower middle, "Tiny Cooling Fan" will hardly speed due to temperature change.
