Features: 7pcs 6mm high-load heatpipes are paired with 2pcs 120x120x15mm fast speed fans, each of which has been dynamically balanced twice for stable and reliable operation.Thermal design power consumption (TDP) of 250watts. The fans adopt pure copper sleeve axial hydraulic bearings for lower noise, stable performances, and longer service life. Conductive air ducts: 2x-fan powerful heat dissipation enhances air circulation, improves cooling efficiency, and rapidly dissipates heat to ensure that the CPU runs quickly and without delay at room temperature. Copper base brazing effectively reduces the temperature of motherboard tubes. Precise Size Adaptation: Ensures perfect compatibility with memory and Input/Output panels. Wide range of compatibility: for LGA1700/1200/115X interfaces and AM2/AM4/AM5 interfaces, supports multiple platforms, and can be installed without additional converters.
