The performance of the notebook can play much, the heat dissipation function is very important. As one of the "three elements" of the notebook cooling module, the role of the fan is unquestionable, so when choosing a notebook, many users feel that the number of fans is the more the better. In fact, there are many factors that affect the performance of the fan. Looking at the same fan, the efficiency will always be greatly different due to these factors.

Among the three elements of the notebook heat dissipation module, the heat dissipation fan can make up for the lack of heat conduction and heat dissipation efficiency of the heat pipe and the heat dissipation fins to a large extent. This is why the heat dissipation performance is greatly different between notebooks with the same hardware configuration and seemingly the same design of the number of heat dissipation fans, heat pipes and heat dissipation fins.
Ensure smooth air duct
The cooling fans for desktop processors are mostly axial flow structures. We can understand them as reduced electric fans that push the air in a vertical direction, thereby accelerating the heat loss from the heat sink at the bottom.
The internal space of the notebook is limited, and the fan and heat dissipation fins can no longer be arranged vertically, but can only be placed in a horizontal direction, so this requires the fan to blow in the specified direction of the side.
Therefore, the cooling fans dedicated to notebooks are mainly of turbine structure, and the fan blades are arranged vertically in an annular shape with the rotating surface. During the working process, the air enters the space surrounded by the annular fan blades from the axial direction, and then is driven by the centrifugal effect driven by the rotation of the fan blades. The centrifugal effect is thrown out laterally, forming a swirling scattered airflow on the periphery of the fan blades, which is blown out tangentially from the air grille mouth by the flow channel.
so notebook fan blades is not the more the better?
Answer: Yes, there is a critical point in the number of fan blades. A balance must be struck between the number of blades and their spacing. Too many blades in too small a space means that not enough air is pushed out. To find this balance, OEMs often evaluate airflow changes through industry-standard simulation software.
       In short, these details affect the cooling capacity of the notebook, but also affect the performance of the notebook.
