Another r4 15 repaste. (i7 8750 1070) Next will be copper shim with liquid metal. :)

I need to figure out how to tame the beast that is the i9 in my 15r4, any suggestions welcome. A repaste stopped it throttling in cpu only benchmarks, but it still throttles in games.

I have a 17 r5 , and i also want to repaste as my cpu temps are in low 90s while gaming . But i have never done it before . Can you guys link me some detailed videos about opening the system up and pasting it? And do you actually recommend me doing it by myself?

Copper shim with liquid metal is a terrible idea because it will move your heatsink up and your heatsink wont make contact with the memory chips or the power inductors anymore.
Where you fix your differential temperatures, you will pay in sheer fps drop because you cant cool your power delivery or gddr5 memory anymore.

So what do you suggest, No copper shim just liquid metal?

sorry for the late reply, I am overseas for business
This post by me should give you some idea, if anything is confusing, don't hesitate to message

Have you ever tried a Graphite pad rather than a shim + TIM?
I’ve had really good results with the IC Graphite pad on my M15.

I haven’t tried the Graphite pad as of yet

The tripod design on the 17Rseries were quite bad. People tried it and it made no difference what so ever.
It’s due to the uneven pressure of the heatsink. I’ve just ordered another tube of kryonaut to repaste.
Liquid metal is still the best performance. I can play at 4.5ghz at low70s and in the 50s for my gpu. But I move around a lot so I had to wipe out the liquid metal in the end and use ceramic paste in the end.

I tried copper shims with normal paste and failed terribly. Remember to post your method and results, please.
I did it on multiple systems and heatsink revisions and with the right thermal pads to account for the different balance, this works fine. My temps never go over 80c for CPU and 70c for GPU.
I always only did the CPU side, never the GPU side, the heatpipes bent slightly to compensate anyway.
I used ICD7 between the CPU die and shim, pressed down and after apply ICD7 on top of the shim before placing the heatsink itself.
I used 0.3mm shims because 0.5mm is slightly too thick.
How did you fail? What were your temps afterwards?
So this method 1: just reapplied thermal paste(artic Mx-4) - - - no shim
I couldn't get an even surface with the copper shim, also I think it makes things worse by having the heat sink slightly raised on the CPU side since I only did one side. So I ended up with worse temps overall (mid 90s). Getting the shim to stay in place was hard enough with normal paste so I didn't try liquid metal with it.
Yeah how thick of a shim? yeah I will definitely have the shim on both sides. 0.5mm thickness
I’m going to try liquid metal without the shim and see how it goes.. so far my temps are about 10-12 c better than the stock bad paste.
Before paste on apex legends: temps were mid 95s. Now they are low 80s after 2 hours .
Next step tomorrow will be clean and try liquid metal.
If you can live with 80s temps, I'd say be happy and forget the Liquid metal. I now have to buy a new board on my own after mine failed due to what I suspect was a leak or spill of the LM.
