Can report the same 9C difference on idle from 54 to 52.

Antutu scores:
Before: 31438
After: 36099

Load temp max from 73 to 64.

Strangely everything feels smoother but could just be bias on my end.
Do you have pics? And how is the sensation at the screen area just above the processor? is it warmer? or you can't feel any difference?

I used a 15x15x0.5mm Copper shim. Thermal pads may be better as they give a cushioning effect compared to the shim. I used prolimatech PK-3 for the SoC-Shim side and CLU on the Shim-Plate side. Of course that isn't necessary you can just use any paste available.

PK-3
CLU
Copper Shim

Couldn't take pics as i didn't have any other cam to take pics with. No difference as my phone was already getting warm anyway, well a difference is that the heat seems a bit more spread out now. I used to feel it concentrated on the top portion where the chip is but now its just a general warmth on the entire top half.

How difficult was the phone to take apart? iFixit rated it pretty low I think.

Its actually very easy. Ifixit has yet to rate it, but others have and it is one of the easiest around

Maybe there's a reason why LG didn't put a thermal pad on the cpu (besides saving a few $$$). I'm not sure that this mod is a safe mod.

The metal plate was never designed to be heat sink in the first place. This isn't something recommended unless you understand the impact of what you're doing. The mod runs the risk or burning your screen.

Have you noticed any issues with the screen after a week plus with the mod?

I just modded mine tonight with the same setup you used and I do notice that the screen gets noticably hotter than before. Although I notice a reduction in thermal throttling in games, CPU temps hover at around 60C now instead of 70-75C when playing games which would throttle down to 1100mhz.

I'll post pics later.
