Acer :: Copper Mod On Aspire 4937G (NVIDIA G105M)

i believe many of u experience gpu reaching near 100 degrees when gaming, causing laptop to jus turn off by itself.

a gd news here..copper shim solve the problem, which means it lower down temp to prevent tat from happening.

received copper shim in my mailbox yesterday.

thickness is 0.044", 1.11mm, 0.1cm

size is 0.75", 19.05mm, 1.9cm (kind of too big for gpu, becos the seller hav tat size for tat thickness, but nvm, look below)

wat i do next is to use a sand paper(fine one, not rough one), i use 1000cw since i had tat at home. lazy to go out to get more fine one.

do it on a flat surface, sand until like mirror effect.

now proceed to dismantle the whole laptop.

it seems tat the heatsink is too small for tat copper shim, but no need to worry, the surrounding alum is a little lower than tat copper.

using Arctic Cooling MX-2. apply on both cpu, gpu, n on copper shim after placing over gpu.

Stress test results

*Ambient Temperature: 32 degrees

Before copper mod, wit default thermal pad. i immediately stop the test b4 it blackout.

After thermal pad was replaced by Copper Shim.
temperature was still steady at 88 degrees after 11mins!
