Tiny Cooling Fan ventilation

"Tiny Cooling Fan" is good or bad depends on the bearing type, blade diameter, fan speed, blade weight, and shape of the blade cutting angle using the fan page. Good heat dissipation fan in addition to a high pressure (the higher pressure can produce a large flow stream), other than large ventilation, reliability is also very important, which the "Tiny Cooling Fan" bearing presents comparative stringent design requirements. Some people think that the heatsink provides better cooling, this is actually a misconception fan "head" large, the speed is usually slow. Big "Tiny Cooling Fan" has the advantage of long blades, heat dissipation area, so the larger gas flow. But if not properly designed, big fan of cooling capacity may not be as good a small fan.
