funny to see how many ppl here still believe in youtubers who are filming their videos "-20C mem temp wow results must do it!" just for hype and likes and not even mentioning potential problems of misalignment (even if you are polishing them very carefully), potential short circuit problems and requirements to maintain thermal paste more often.

if the thermal pad is 2MM make sure you use 2mm copper shims.

It's a mistake already in the very first point. Copper pad is not flexible and can't be compressed. if you add thermal paste on top of 2mm copper pad where previously 2mm silicone thermal pads were installed, it will add even more making it 2mm+ leading to bad contact with GPU itself and causing overheating.

If its all a mistake how come its working perfectly? Even the guy in the video I dropped above did the same thing and still get the best result vs using a thermal pad, the same size as well.

I do not understand why create so many problems for yourself because of 5-6 degrees Celsius on memory.If copper thermal pads were maintenance-free, you would need to change the thermal paste more often.

I don't understand your English very well, are you saying that copper pad can only take down 6 degrees off RTX graphic cards? That's totally not correct, the first guy that took this step was on Youtube and damn the result is so good, you need to check this video out.

You are the wrong @soda37, copper shims are the best thing you can do to your 3080,3090 and 3070Ti graphic cards, you just need to do it the right way like

1. Make sure you use the exact thermal pad size to copper shims, if the thermal pad is 2MM make sure you use 2mm copper shims.

2. Some copper shims come with sharp edges, use sandpaper to smoothen the copper shims so that they will sit perfectly on the chips.

3. Use heat resistance tape like kapton tape to cover every space, capacitor and resistance around the mem chips just for safety purposes.

4. Use the thermal paste on the chips before adding the copper shims, you must add the paste to both sides of their copper shims before putting the heat sink on.

You will get a very good result, 30°C gone from mine after 110°C start showing on my 3070Ti and 3080, its been two weeks now, from 110°C to 76°C, fear is a bastard.

I like that reminds me of Dune's "...Fear is the mind killer..."

I'm copper modding few GPUs I have and I need help with a tool that I can use to cut copper shims easily, I will drop a picture below showing the type of copper shim I got and im looking forward to cutting it into 15mx15m size.

copper pads is the worst thing you can do for the card longevity, too high risk of breaking mem chips or short-circuit power lines leasing to GPU death. Better just buy good 12.5W termal pads.
