Copper Shims for Laptop and Console Repair

This set provides ten copper shims measuring 20x20x0.8mm for DIY thermal management. They target builders servicing laptop BGA CPUs, VGA chips, RAM ICs and consoles such as Xbox 360, PS2, PS3 and PS4. The shims replace aged thermal pads that have lost conductivity over time.

Sustained Thermal Transfer at 401 W/mK

Each shim delivers a rated thermal conductivity of 401 W/mK, far above ordinary copper at 20-30 W/mK. This high value maintains consistent heat flow from the die to the heatsink during prolonged gaming or compute sessions. The material resists the aging and pump-out that degrade polymer pads under continuous load.

Verify Die Height and Mounting Pressure

Measure the gap between the bare die and the cooler cold plate before ordering; the 0.8mm thickness must match that clearance exactly. Ensure the mounting mechanism can supply even pressure without bending the thin copper sheet. Buyers needing thicker or thinner gaps, or those without a flat contact surface, should look elsewhere.

Questions about this item

Will the 0.8mm copper shims add noticeable heat or noise when running all day?

The shims are passive copper pieces with no moving parts, so they generate no noise and add no heat of their own; they simply spread heat from the component to the cooler.

What else must I already own for these 20x20mm shims to work?

You need a compatible CPU, GPU, RAM or BGA chip with a flat surface, thermal paste or pads for both sides of the shim, and a heatsink or cooler that can clamp the stack together.

Can I use these 10 copper shims alongside the original thermal pads in my older Xbox 360 or PS3?

Yes, the 0.8mm thickness lets you replace or supplement aged thermal pads on Xbox 360, PS3, PS4 and similar consoles, restoring contact between the chip and the stock heatsink.
