Hi @SoulLeadian  does the Alienware m15 Thermal Testing, Overclocking and Undervolting video Here answer your question? 

Every gaming laptop in the thin and light category has thermal issues right now. It's an intel chipset thing, not something the manufacturers can really address.

Intel's 10 nm process is overdue due to delays in the research and development process, which has resulted in Intel slapping more cores on the outdated 14nm process CPU's, which is what is causing the whole CPU overheating thing.

Hi, Your temps are too high, even at idle, have you done a repaste?

I recommend using Noctua NT-H2 paste, from what I've seen Dell's paste is not good at all. You will continue struggling until you do this, mainly because the heatsink is not doing its job efficiently. These laptops are great, they just lack some care when built...

Hi @SoulLeadian  note you report Alienware m15 R1 too hot, again.

Hopefully the Alienware Thermal Repasting process was used, see video Here. Did this video use "Thermal Grizzly Conductonaut Liquid Metal Thermal Paste" with a Thermal Conductivity of 73 W/mK.

You have already used Cooling Master to re-paste your CPU and GPU. There is a best thermal paste review Here and the "Cooler Master MasterGel Maker Nano" with a Thermal Conductivity of 11 W/mK is included in this review.

A high thermal conductivity paste is good for serious overclockers and essential for the m15 R1 whose CPU and GPU run hot for other reasons. It is also worth noting to check the paste Lifespan, shelf-life (e.g. 3 years) and life after installed (e.g. 5 years). 

Check to see if you are you are not using shelf-life expired paste and/or that its has previously not been installed for more that its rated lifespan. 

And one thing to mention about liquid metal, your cpu is delided right?

That means it’s a BGA cpu and since it uncovered the copper heatsink coating will wear off cause of the liquid metal and since the bare die of the cpu is uncovered the liquid metal is electrically conductive.
