Features: M.2 hard disk copper heat sink copper conducts heat, dissipates heat efficiently and cools rapidly. Copper heat dissipation can effectively cool down and protect the data storage safety of equipment. Strong heat dissipation continue to strong, and the heat of electronic devices is transferred to the heat sink through heat, thus reducing the working temperature of electronic devices and improving the stability of system. The thickness of 1mm copper sheet can be suitable for most notebook computers, and at the same time, the thickness of copper sheet can better provide heat dissipation effect. Super thermal conductivity adapts to mainstream notebook heat sink and silicone grease sheet, which only increases the installation height by 2mm, which is suitable for the installation of most notebook computer M.2 hard disk Specifications: Component:Copper Size:Approx.73x22mm/2.87x0.87inch Package Includes: 1 Set M.2 Heatsink note: 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
