The DELL seems to be tethering at the 'edge' of thermal threshold for the CPU. My point was that in the G5 at least, it seems that (thus far) dropping temperatures was a challenge at best. Seeing how laptops have uneven cooling assemblies and poor thermal efficiency of the cooling assembly in the G5 15 SE, it is inconclusive whether Kryonaut (or any other thermal paste) would be sufficient in bringing down temperatures on the CPU. Application of Kryonaut might be beneficial, but someone needs to test it out. And if Kryonaut is able to do that, then it stands to reason that Liquid Metal (with foam barriers) might be able to bring the temperatures down to (possibly) 95 degrees Celsius for the CPU when its stressed - if this is achievable for the CPU with LM, it might also allow the GPU to function as it should. That said, as you mentioned, disabling the turbo boost for the APU seems like the best option for the DELL (in which case, only Kryonaut would be needed - and I'd apply that thermal paste on both CPU and GPU). As for GPU undervolting, as I mentioned before, it should be possible to enable Wattman via MSI Afterburner. Wattman may not visually apply voltage changes, but it seems that it still applies them either way... it would need to be tested while a GPU benchmark is running to see whether the temperatures on the GPU are dropping (or if the performance is improving). What also concerns me is what Frank Azor mentioned... and that is the fact that in the DELL, the 5600M is drawing 70-80W as opposed to the 90-100W as it should. I don't know whether this GPU power limitation is because of the inefficient cooling or it was set like that in the vBIOS. If its the vBIOS, then it would be a problem and the GPU would never be able to achieve its full performance (which should be on the level of RTX 2060 at least) without vBIOS modifications ... but alas, someone needs to test this out.
