Feature: 1. High Quality Material: Made of copper with a high thermal conductivity of 386.4w/(m.k), chemically polished to prevent burrs and short circuits; After multiple grinding and milling processes, the has undergone oxidation resistance treatment, which does not rust or oxidize, making it more than ordinary copper sheets. 2. Combined with high-performance thermal conductive silicone pad, it has better heat dissipation and is not easy to leave fingerprints. The will not oxidize and darken after long-term use. 3. With Thermal Conductive Silicone Pad: Thermal conductive silicone grease is soft and flexible, paired with high-performance thermal conductive silicone pad, which can tightly fit the of electronic devices. It can also fill in gaps in hard disk particles, keeping the heat dissipation fins at the same height, achieving rapid heat dissipation and extending the lifespan of the hard disk. 4. Snap Fit Design: Adopting a snap fit design with strong compatibility, the heat sink can be directly fixed to the hard drive, eliminating the height increase problem caused by rubber ring fixation. Specification: Installation Tutorial: 1. Clean the dust and oil stains on the of the solid-state drive to facilitate the installation of thermal conductive silicon wafers for a more complete fit. (Install and fit the entire piece) (Small piece can be accurately attached to the main control and cache chips of solid-state drives, providing more accurate heat conduction) 2. Tear off the double-sided protective film of the thermal conductive silicon film and onto the hard drive itself. (The thermal conductive silicon film has a slight viscosity and can be easily adsorbed on the hard drive) 3. Add a heat dissipation copper plate and fix it without a rubber ring. size: Length 74mm x Width 22mm x Thickness 0.8mm Material: copper colour: copper note: accessories are randomly colored.
