The surface of the motherboard 2 is fully in contact with the air and heat exchange is carried out, thereby cooling the motherboard 2, thereby improving the cooling efficiency of the motherboard 2; at the same time, the air outlet 34 and the exhaust hole 12 are both close to the motherboard 2, so that the air in the installation cavity 31 is fully in contact with the surface of the motherboard 2 and then discharged from the exhaust hole 12 and the air outlet 34, increasing the multi-directional discharge of air in the installation cavity 31, forming a more effective heat dissipation channel, and improving the cooling efficiency of the motherboard 2 by 22%; at the same time, the installation cavity 31 shields the radiator 41, and the inner wall of the installation cavity 31 changes the propagation path of the sound waves generated by the rotation of the fan, causing part of the sound waves to be reflected back to the fan or absorbed by the inner wall of the installation cavity 31, thereby reducing the sound energy directly propagated outward, reducing the noise of the NAS host during operation, and controlling the noise of the NAS host to below 28dB(A), thereby improving the noise reduction performance of the NAS host.
