XPS 8950, processor upgrade, i7, 13th gen?

This system will not take anything other than a 12th gen CPU.

@ejn63​ Thank you. All i find on Ebay are Intel Core I7 12700 ES QXQ4 8+4 12 Cores 20 Threads LGA 1700 CPU Processor.

Do you know what ES stand for. Is same as regular Intel Core I7 12700

ES = engineering sample.  They are not supposed to be resold -- they're for manufacturers to use in testing boards, systems, etc.  You have no way to know whether they're unused or have been thrashed to near destruction -- buy with care.

These aren't inordinately expensive brand new and warranted.  If you decide to chance an ES unit, make sure the discount makes the risk worthwhile (and that the seller is reputable as Intel will not warrant an ES CPU to an individual buyer).

@ejn63​ Thank you. I will just get retail on Amazon or newegg.

Thanks for your help

Op, be thoughtful and marking accepted answer after you received the answer(s) for your query would help others with the same or similar questions.

@vicm98​  To answer a couple of your other questions...

The i5 you have is 65w base with 117w max turbo.  The i7-12700 has the same base watts, but has 180w max turbo.  I don't know if you'd ever hit max turbo, or if the motherboard even allows it.

If you have the pancake style heatsink, there's a couple of options worth considering.  One is a tall heatsink with copper pipes and a fan in the middle.  Second option is liquid cooling.  See screengrab below.  I Googled "XPS 8950 heatsink."

As for PSU, your RTX 3050 is only 130w.  Needing a PSU upgrade is unlikely.

I don't know much about VRM heatsinks.  But it certainly doesn't sound like a bad idea to keep things running cool.
