I have that laptop and yes it has 2 fans but I assume 2 heatpipes but I am not sure. I am using an old dock not sure what model number but I have a 130w barrel plug brick that plugs into it and for some reason it still gives me a warning that the power adapter doesn't have enough power but even while doing heaving tasks I don't see any battery drain when gaming on this. I can run the Outer Worlds and Cod Warzone 2.0 at low settings 900pish and i get 70-90 fps with intel xe gpu usage at %100 and cpu usage never goes past 40% or 50% you shouldn't have any issues with that. Hope this helps.  
Hi, I'm considering to buy an XPS 15 9520 with the i5-12500H CPU, without a dedicated GPU. I suppose this configuration has the same cooling system (2 heatpipes with 2 fans) as the one with nVidia GPU, so it should run cooler and quieter. Can someone confirm this please? Or any other experience with this configuration? This no GPU laptop has a 90W power adapter, so I suppose the Dell Dock WD19S USB-C 130W with 90W power delivery should work well even if the 180W version is recommended by Dell. Is it so? Thank you.
