Copper Shim Heatsink

This Copper Shims thermal conductivity up to 401w/mk, and ordinary copper thermal conductivity is only 20-30w/mk. CPU and GPU graphics card in the inside part of the laptop using a thermal plastic thermal conductivity, thermal plastic at high temperature for a long time easy to aging, and ultimately lost, leading to overheating of the CPU or GPU, the Laptop will not start after overheating. And this copper heat sink solve thermal problems caused by frequent crashes laptop, etc Features: - 100% new and high quality. - Smooth surface, smooth edges and corners, no burr. - Has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, can be welded and brazing. - To improve the thermal conductivity of filler, applies to the graphics card and radiating module and conduction gap, reduce the repair rate card. - Applications: mobile phone, tablet, notebook CPU chip, North and South Bridge chip, memory chip, memory chips and card small chip, small chip hard all kinds of computer electronic chip auxiliary heat. Instructions: - Cleaned surface of your chipset and heatsink and be sure no residu compound in it. - Be sure you have painted the silicone grease when fix the heatsink. - Be more patient when do it.
