Micro Cooling Fan hot swap

"Micro Cooling Fan" enough cold air subjected to heat exchange with the heat sink, the cooling effect is also not good. General requirements of aluminum fin heat sink fan pressure is large enough, and the copper heat sink fin fan air volume is required to be large enough; more dense fin heat sink fins relatively sparse compared to the heat sink, the need greater pressure of "Micro Cooling Fan", otherwise poor air flow between the fins, the cooling effect will be greatly reduced. So different radiator manufacturers will meet the appropriate amount of wind, air pressure of the fan as needed, rather than the pursuit of a single volume or high wind pressure of "Micro Cooling Fan".
