Computer motherboard thermal solution

Introduction of computer motherboard:

Computer motherboard, also known as motherboard, system board, logic board, motherboard, backplane, etc.
A typical computer motherboard can provide a series of joints for the processor, graphics card, sound card, hard disk, memory, external devices and other devices to join. They are usually plugged directly into the relevant slots, or wired. The most important component on the motherboard is the Chipset. The chipset usually consists of a north bridge and a south bridge. The north bridge is mainly responsible for controlling the communication between CPU, memory and graphics card, while the south bridge integrates many circuits and control modules such as boot, reset, CMOS circuit, USB, IDE, SATA, PCI, etc , they are the core of the entire motherboard.

With the trend of increasing the frequency and speed of computer motherboard devices, the heating power has become the main technical bottleneck. How to obtain the optimized transmission performance through the design and introduction of heat-conducting and heat-dissipating components, and meet the requirements of high reliability, cost, etc. Different needs have become the key to heat dissipation engineering.
