Aluminum Case Matel Shell Heatsink Aluminum Alloy Box Assembled Heat Dissipation Shell For Raspberry Pi 4

  Features: Ultra-thin design Easy to install Fast Heat dissipation Smooth and straight aluminum material All ports and slots of the case can match with Raspberry Pi 4 Computer Model B perfectly Open case design, you don't need to worry it will effect wifi signal any more Reinforced aluminum material, lightweight and durable, long-lasting stainles We use silicon cooling pad (the thickness is only 0.5mm) to touch the shell body to dissipate heat. You can use the CPU grease to relace the silicon colling pad to get better heat dissipation.   Dual Fan:  Noise: 18dB  Low Power Consumption Design  Dual Cooling Expericnce, More powerful heat dissipation  Very Quiet Cooling Fan, get rid of the fan noisy   All of the Fans were Tested by Our Engineer, Very Nice Quality Control  Update Thermal Tape Can Make Sure Best Heat Conduction Effect
