Technical Field

[0001] The utility model relates to the technical field of heat dissipation fans, in particular to a high-performance CPU heat dissipation fan. Background Art

[0002] Among the internal accessories of a computer, the CPU on the motherboard is one of the main accessories, ensuring that the performance of the entire computer can be fully utilized. However, the CPU will generate a lot of heat when working. If the heat on the CPU is not dissipated in time, it will easily cause the computer to crash, and it is more likely that the CPU will burn out. Therefore, a cooling fan is needed to dissipate the heat of the CPU.

[0003] When the existing cooling fan is used for a long time, due to the lack of a dust blocking device, a lot of dust is easily accumulated on the cooling fan, thereby reducing the heat dissipation performance of the cooling fan. For this reason, we propose a high-performance CPU cooling fan. Utility Model Content
