Choose from the "Micro Cooling Fan" appearance from the outside surface should be relatively thick overall, relatively pure colors (especially black, the color of the fan is not important), at the edge of the box leaves no edges, looking blades Thickness (very important since too thin easy to break), there is not much time Yong Shounie frame deformation. First, the choice of "Micro Cooling Fan" must be able to provide sufficient amount of exhaust, under the high temperatures of the hot air inside the cooling device; when a relatively low temperature and heat flow is relatively less time to do the opposite of work. Secondly, the "Micro 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.
