First, if the "Small Cooling Fan" stop turning, and probably one of the reasons is that the fan speed does not reach normal speed radiator needed for the work. As a result, the radiator "Small Cooling Fan" is very likely because they are not supported by sufficient momentum slowed speed or stop working, there would be a corresponding cooling effect of greatly reduced. At this time we can try to "Small Cooling Fan" blades make some adjustments so that it can meet the speed requirements of the appropriate power radiator work, this one to not only solve the problem, but also eliminates the need to replace your new device trouble.
