Feature:1. APPLICABLE: SSD copper heat sink is designed for M.2 B Key or B Key disks and works perfectly with M.2 2280 SSDs, suitable for Samsung 850 EVO 860 EVO 960 EVO 970 EVO 950 PRO 960 PRO 970 PRO 980 PRO SN850 SN750 SN570 Firecuda 530 Crucial P2 Crucial P5 Plus and more.2. HIGH THERMAL CONDUCTIVITY: Hard disk heat sink is made of red copper with a thermal conductivity of up to 401W (m.k) and chemically polished to prevent burrs and short circuits. Dramatically increase the heat dissipation area of M.2 storage disks with 10C 30C cooling effect.3. 2 THICKNESSES OF NANO THERMAL PADS: 2 thicknesses of nano thermal pads with high performance 5W m.K thermal conductive silicon wafers that fit snugly on the surface of electronic devices, filling in the gaps of hard disk particles and keeping the heatsinks at the same height.4. ANTIOXIDANT TREATMENT: After multiple milling processes, the surface is treated with antioxidant to prevent rust and oxidation. It is not easy to leave fingerprints. Precise size calculation to prevent installation deviation and short circuit, suitable for laptop installation space.5. STABLE INSTALLATION: M.2 2280 SSD copper heat sink installs stably and protects your M.2 SSD better, with good heat dissipation performance, perfect for Laptop PC, for Play Station 5 heat dissipation.Specification:Item Type: SSD Copper Heat SinkMaterial: Red Copper, SiliconeHeat Dissipation Copper Sheet Size: Approx. 75 x 23 x 0.5mm / 2.95 x 0.91 x 0.02inThermal Conductive Silicon Wafer Size: Approx. 16 x 13 x 0.8mm / 0.63 x 0.51 x 0.03in, Approx. 16 x 13 x 0.5mm / 0.63 x 0.51 x 0.02inProduct Process: Anti Oxidation ProcessProduct Use: For M.2 2280 SSD, Does Not Support For MSATA Disks, Support For B Key, B Key Disks (Not Including M.2 SSD SSD).Package List:1 xSSD Copper Heat Sink1 x 0.8mm / 0.03in Thermally Conductive Silicon Wafer (5 Pieces)1 x 0.5mm / 0.02in Thermally Conductive Silicon Wafer (5 Pieces)1 x Screwdriver1 x Triangle Cocking Piece2 x Screw1 x Plastic BoxNote:Please allow some error due to manual measurement.
