Features: We adopt copper sheet with high thermal conductivity of 6.0w/m.k through multiple processes and plate oxidation resistant treatment, which are more durable than ordinary copper sheet; The heat sink enhances heat dissipation by increasing surfaces area and thermal conductive materials, effectively transferring heat from the ssd to the surrounding environment. Better heat dissipation with high-performances thermal conductive silicone chip, and not easy to leave fingerprints; The improved design of this heat sink ensures efficient heat dissipation for M.2 SSD, optimizing its functionality. Designed for users who want to optimize the stability and reliability of their M.2 SSDs by controlling temperature and reducing the risk of overheating.
