- Seal type independent air duct, which can discharge heat well and dissipate heat quickly; 2. With OLED temperature display, the M.2 heat sink is endowed with the function of real-time temperature display; 3. It is made of aluminum alloy and processed by CNC in many processes. The surface texture is fine with anode sand blasting process; 4. With small turbine fan cooling fan, air cooling more efficiency; 5. 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.
