Don't see that as helping much, you're adding more material and more resistance to heat transfer. Also it not being polished to a shine means that you have less effective contact due too imperfections and thermal adhesive or pads won't help. Leave the copper shim out imo
You're better served with higher efficiency thermal pad
Shims help when you have plenty of surface to contact and can use thermal paste (the gpu itself for example) vrms are too small and the thermal pads contact them and the area around themEdited by Echoa - 7/6/16 at 3:16pm
