Features: Brand new and high quality Chemical polishing, prevent burr short circuit; Anti-rust, anti-oxidation passivation agent, no rust, no oxidation. Precision dimension calculation, prevent installation deviation, short circuit. The heat sink adopts nickel plated copper plate with high thermal conductivity. Radiators dissipate heat faster by exchanging heat in contact with air. The heat sink is used with ordinary silicone grease,but not other thermal conductive materials, such as thermal pads, metal silicone grease, etc. The thermal conductivity and heat dissipation of the made graphics card is pure copper, with a thermal conductivity of 386.4W/M.K. Specifications: Material: Copper Color: Shown as pictures Package Includes: 1 x GPU Thermal Pad note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
