10 Pcs Copper Shim 20x20mm for Laptop, Desktop, Computer GPU & CPU Heatsink - High Thermal Conductivity Heat Pad

• 【Laptop Copper Pad】GPU CPU thermal heatsink copper pad provide 6 kinds of thickness (0.3/0.5/0.8/1.0/1.2/1.5MM) for you to choose. Easy installation for your DIY projects,with good heat dissipation effect
• 【Great Item and Ideal for Reconditioning old GPUs】Thermal conductivity is up to 401 w/mk, very nearly silver's thermal conductivity 409 w/mk, much higher than ordinary copper pad (20-30w/mk)
• 【Very Versatile Little Tools】Exposed to the air, the copper will inevitably oxidize and turn dark, but the cooling effect does not be affected. If you still worry about it, you can polish the of this copper shim by fine sandpaper or toothpaste. You can use them to spread heat between heatsinks, or connect various components
• 【Powful Fuction】heatsink copper shim thermal pads can solve laptop frequent crashes and other problems caused by thermal conductivity.
• 【Broad applicability】 the copper can be applied to the desktop computer north and south bridge connection, graphics card thermal conduction.
