As the core of the mini computer hardware, the heat dissipation performance of the ITX motherboard is crucial to the stable operation of the system. While pursuing ultimate compactness, how to ensure heat dissipation has become an important consideration in the design of ITX motherboards.
First of all, the heat dissipation performance of ITX motherboards is mainly achieved through components such as heat sinks, heat pipes, and fans. Due to the small size of ITX motherboards, the heat dissipation space is relatively limited, so the heat dissipation design is more refined. Heat sinks are usually made of materials with high thermal conductivity to accelerate heat dissipation by increasing the heat dissipation area. The heat pipe uses the principle of heat conduction to quickly conduct the heat of key components such as the CPU to the heat sink, and then dissipates it into the air.
However, with the advancement of technology, fanless designs are gradually being used in ITX motherboards. The fanless design not only further reduces the size of the motherboard, but also reduces noise, providing users with a quieter environment. In a fanless design, heat dissipation performance is mainly achieved by optimizing the heat sink structure, using efficient heat dissipation materials, and enhancing the heat conduction efficiency between the heat sink and the heat source.
For fanless designed ITX motherboards, the key to thermal performance lies in the contact area and contact pressure between the heat sink and the heat source. In order to improve the heat dissipation effect, some ITX motherboards use a reflow soldering process to tightly weld the heat sink and the heat source together, thereby increasing the contact area and increasing the contact pressure. In addition, some high-end ITX motherboards also use liquid metal heat dissipation technology, using the high thermal conductivity of liquid metal to further improve heat dissipation performance.
To sum up, the cooling performance of ITX motherboards is closely related to the fanless design. By optimizing the heat dissipation design, using efficient heat dissipation materials, and enhancing the heat conduction efficiency between the heat sink and the heat source, it is possible to ensure that the ITX motherboard achieves good heat dissipation in a small space, thereby ensuring the stable operation of the system.
