Question Resocketing Laptop CPU from a i7-8750H to a 10750H ?

[Gamefreaknet]

NOTE: The above is my current plan as I am not 100% on:
- Swapping to a CPU with a higher core count
- If my motherboard will actually "allow" for this? (Alienware 03R2RY - i7 8750H, 2070MQ)

As of recent I've noticed the thermals across the CPU (using HwInfo) is "unstable" (there can be as much as a 15c - 20c thermal difference between 2+ cores sometimes) which can cause it to throttle because 1/2 of the 6 cores are hot (often 1/2 cores being 90c - 100c whilst other cores are closer to 70c - 80c).
Admittedly it has been a year now since I got it repasted (this will be its 3rd repaste if I do repaste it - I have owned this laptop for around 5 years now).
I am also intending to upgrade its memory (currently 2x 16GB - 32GB total) to 64GB (2x 32GB) however the memory upgrade will cost around £100ish.

The main push to a "better" CPU is I often find my CPU will be around 60% - 100% utilized whilst my GPU rarely goes over 15% / 20% usage (thus I suspect a slight CPU bottleneck).

I do intend for the swap to be to a CPU with:
- Same TDP
- Same core count (not sure if the mobo will accept a CPU with more cores - I dont see why it wouldnt but to be on the safe side although I wouldnt mind more cores if it's fine)
- Higher Base Clock (definitely one of my core preferences for the upgrade)

The 10750H fits those criteria quite nicely however I am fairly certain that the current CPU (i7 8750H) is soldered and I'm not too certain of how many shops would be willing to attempt a de/resolder job (likely due to how sensitive such a job can be).
Any Advice?

Full Laptop Specs:
Model: Dell Alienware M17 03R2RY
i7 8750H (with UHD 630)
RTX 2070MQ (8GB Vram)
2x16GB 2667Mhz RAM (modified)
1TB SATA III SSD + 2TB M.2. NVME SSD (both modified)
Killer E2500 Gigabit Ethernet Controller (with wireless)

(NOTE: Available on Intel Site: Socket - FCBGA1440 )

FCBGA is Ball Grid Array, which means both cpus are soldered to the motherboard.

The chipset on that motheboard is a HM370 which means it will only allow 8th and 9th gen CPU's.

More specifically they are showing only 8th gen i5/i7 and 9th gen i7. Since Alienware is owned by Dell, they like to stick to allowing only certain things, and if the bios does not have the microcode for any other CPU it won't work or work to its fullest.


But in short, trying to put a 10th gen cpu on that board will not work.

Are there brands that allow for more modularity?
I do know of the Framework Laptops (although from what I last saw they tended to be on the slightly pricier side) however are all brands pretty locked to only allowing certain things to be tweaked/upgraded/etc... or are some brands (like Asus, Acer, Razer, etc...) more "allowing" for things like CPU swapping aswell as the Memory, Storage, etc...

Everything is custom designed in most laptops. Things like the cooling is designed for that cpu/gpu combination. It is not likely to work on a cpu that puts out more heat.

This is almost silly to think about. First go find out what someone would charge just to swap the cpu with one that is exactly the same. There is a huge amount of time required to just dissemble and reassemble the laptop and then it takes very special tooks and someone very skillful to actually solder a cpu.

I bet it will be at least $250 if not a lot more.
