Cooling fan heatsink area the greater the effect will be better?

　　We usually will note that due to the heat by conduction to the heat sink, and then bring the cold air blowing fan products work and the heat generated when the heat sink away, while the cooling fan and the number of calories that can be conducted heat sink area size. Fan

　　In general, the contact area of the heat sink and the air the greater the cooling fan cooling, the better, but the premise of this argument is that there is a certain, and that is the case in the case has enough free space. If your computer's chassis had space for heat dissipation is not large, there is not enough space left in it, a very large area is difficult to install the heat sink into the chassis, even if barely able to install the chassis, much of the contact area will be blocked fins hot air around quickly dissipated, leading to an overall internal chassis temperature is too high, so that affect the performance of the entire computer, so I recommend the size of the heat sink area should be chosen to match the chassis, not a pursuit of space.
