Features: The aluminum cover plate with holes, which accelerate air circulation and allow the heat generated for M.2 SSDs to dissipate more quickly. Cooperate with the internal fan system to better enhances the heat dissipation conversion effect. The heat dissipation aluminumalloy cover plate combined with PVC filter can greatly reduce the accumulations of dust in the SSDs expansion slot and enhances heat dissipation performances Allowing heat dissipation system to ensure air flows through the radiator to improve cooling capacity and prevent SSDs overheating and deceleration. The better the SSDs cooling effect, for M.2 SSDs hard drive will be.
