Seal type independent air duct, which can discharge heat well and dissipate heat quickly; With OLED temperature display, the M.2 heat sink is endowed with the function of real-time temperature display; It is made of aluminum alloy and processed by CNC in many processes. The surface texture is fine with anode sand blasting process; With small turbine fan cooling fan, air cooling more efficiency; The radiator is equipped with nano silicone thermal pad, with a thermal conductivity of 8W / km, which can well conduct the hard disk to the heat sink.
