XIANQI Material: Aluminum Heat dissipation method: air cooling The compaction process is adopted, the base is polished, and each fin is in zero-distance contact with the CPU to dissipate heat quickly. Wavy fins have a larger heat dissipation area The fins are all processed in a wave-shaped curl, the heat dissipation area is larger, and the peripheral gap is smaller, and the wind force at the edge of the fan can be effectively used to improve the overall heat dissipation performance. The "wings" of the 9CM ball bearing fan have a service life of more than 30,000 hours, the noise is less than 18dBa, and the maximum air volume reaches 53.5CFM. The fan blades are removable and washable for easy cleaning. Support multi-platform compatible Support Intel LGA7751155N 1156 platform, and AMD AM2AM2+\AM3FM1 platform to meet different customer needs. Packing list: 1*radiator
