TLDR: Copper heatpipe modding added the same amount to sustained wattage as LM did to stock PTM.
So my brother and I have been messing around with copper heat pipe modding on the L7i, coming to the conclusion that adding the most conductive mass at the shortest possible route between CPU and heatsink (see pic) will add the most sustained wattage to your laptop. You may not even need to bother with the left hand side of the CPU in the pic as that only added like 5% benefit (but should theoretically benefit the GPU wattage more).
If you want the same results while having everything neatly tucked in your laptop that won't bulge or anything, then further info below:
The way I built it is as follows: make a base TIM on top of VC with PTM7950 (yea I know, maybe putty would have sufficed but I digress) . On top you add 1 mm thick copper heatpipes all the way to the heatsinks (10-14 mm pipes, 3 to 4 next to each other). Anything thicker than that and you will end up with a ugly backplate that won't fit. On top of that you add a thicker 2.5 mm heat pipe that is slightly shorter. You stop well before the first layer or else your plate won't fit. Add generous amounts of putty (TH949/TGPP10) to mold the pipes together. On top you add yet a third layer of pipes to connect to the secondary heat pipes at the sides of the laptop. Sprinkle heatsinks here and there where you see fit.
The effects are substantial.
Wattage output at the end of CB R23 cycle with no PL2 limit (room temperature):
-With stock PTM: 115W (didn't include in graph)
-With conductonaut LM: 130W
-With conductinaut LM + heatpipes as shown: 155W
With a quick bench with AC cooling to show the proof of principle, managed the following:
CB R23 score: 25888
Haven't tried timespy.
TS settings:
Overclocks: 4.8P/3.5E
Core UV: -148 mV
E/P Cache UV: -40 mV
Tbh idle temps are -4c lower compared to even LM.
