XPS 8940, CPU upgrade from i7-11700K to i9
I'm hoping to upgrade my XPS 8940 i7-11700K to i9. I'm not sure if it will be the i9-11900K, it might be a slower one. However, do I have upgrade my current specs (power, cooling etc) to support any i9? If so, which would works best without upgrading my current specs? If I have to upgrade, which parts do I need to upgrade?
Current Pre-Built Specs:
500W Mineral White Bezel Chassis including optical drive
32GB, 16Gx2, DDR4, 2933MHz
11th Gen Intel(R) Core(TM) i7-11700K processor (8-Core, 16M Cache, 3.6GHz to 5.0GHz)
NVIDIA(R) GeForce RTX(TM) 3060 Ti 8GB GDDR6 (LHR)
a) Can I upgrade by simply swapping the CPUs (assuming I follow the correct CPU switching steps)
b) Do I need a larger PSU than the current 500W?
c) Do I need to upgrade the current CPU fan? (Currently using the pre-built "luxury cooler" that comes with this)
This is similar to this post: (However I'm starting with higher specs)

You already have a 95 watt processor, so your PSU is good. If you are going to the trouble of upgrading . . . get the best CPU available, which would be the i9-11900K. As in the thread you linked, I would always recommend AIO liquid cooling for a 95 watt processor. I don't know what the "luxury cooler" means.
How are your CPU temps with your current cooling solution under your particular usage regime?

Since the XPS-8940 never shipped with Liquid-Cooling (so there is no easy/established provision for it) ... I would suggest you keep what you have ... especially if everything is now working 100% properly.
IMO, that Intel-i7 and the RTX-3060-TI are a nice match.
Does it boot from a NVMe-SSD? If not, that will definitely add some speed if upgraded-to (480gb NVMe-SSD or bigger for C-Drive).
Is any other drives (that you load programs and/or games from) at least a SATA-3/600 based SSD?

For all the troubles of cpu swap etc., practical benefit of this swap seems very little.
https://cpu.userbenchmark.com/Compare/Intel-Core-i9-11900K-vs-Intel-Core-i7-11700K/4110vs4107
the two cpus performance is too close to be worth it.
But if you were to sell this pc, i9 would sound better than i7, therefore this swap would be good to buff up the spec.
For yourself, if you would like to feel better about the cpu spec regardless of actual performance boost, maybe do it if you can sell off the i7 to defray i9. For more immediate tangible performance boost, better invest on faster gpu than 3060ti. A gpu investment has more future proof than cpu. You can move the gpu to XPS 8950 but you can’t move the cpu.

Hello, do you have steps of parts or a video of how to upgrade to this version shown here?

Both are 120mm All-In-One liquid cooling solutions. The Corsair H80i is a thicker rad.
