20 pcs 15mmx15mm 0.3mm to 1mm Heatsink Copper Shim Thermal Pads for Laptop IC Chipset GPU CPU

Description:
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

Feature:
1. Thermal Conductive coefficient: 400W/(m.K)
2. With this copper pad to greatly lower gpu temperatures, can be used for Graphics card, north bridge, CPU chips.
3. It can be applied to HP,Dell,Acer,Thinkpad and all alptop and computer heatsink solution!
