And you are right, its better to get the K version to make use of the quick sync feature.
That, and also for redundancy iGPU offers.
I am not sure about the D12L cooling a 300W CPU. NSPR of 148 is equivalent to 250W of heat load?
D12L won't hold up for OC or 100% load, but for daily driver it is enough.
In that TechPowerUP review you linked, 2 pages on (page 24), temps of i9-14900KF are seen;

NH-U14S is able to keep the CPU on stock clocks at 81.3 C during gaming and 93.8 C at full load. That's below 100 C what CPU is capable of. NH-D15 drops those temps ~5 C. So, air cooling is enough.
Hey , Aeacus , i want to change the MB to 790 (ASUS TUF Gaming Z790-Plus D4 Motherboard Socket Intel LGA1700) , also the PSU , to CORSAIR CX750 ATX 750W Power Supply - 80 Plus or Corsair RM850e (2023) and Cooler to Noctua NH-D15S chromax.black , what do you think.
That's much better MoBo.
Same goes to CPU cooler, essentially king of air coolers.
But why do you want to cheap out on PSU?
🤔
Corsair CX, at best, is only good for office builds, without dedicated GPU.
Corsair RMe is better than CX, but worse than Seasonic Focus.
My take on this is: if you have money to buy Core i9 and RTX 4070, then you'll also have money to buy proper PSU. And while i suggested Seasonic Focus before, which is still good PSU, but now, i'd switch my suggestion to Seasonic PRIME, preferably 80+ Titanium unit. Since that PSU is one of the best, if not the best PSU money can buy. And i know this 1st hand since i have two Seasonic PRIME TX-650 PSUs in use (one in Skylake build, another in Haswell build, full specs with pics in my sig).
Take your pick,

Now, if you can not afford proper PSU, then don't buy Core i9. Instead buy Core i7 which is cheaper, so that you can have money for proper PSU. Or don't get RTX 4070, instead get RTX 4060. There are loads of ways to save money for proper PSU.
Keep in mind: Since PSU powers everything, it is
the most important component inside the PC.
Moreover, with that high-end hardware, i'd also look towards UPS as well. True/pure sine wave output, line interactive topology, in ~700W/1200VA capacity.
E.g CyberPower PFC Sinewave CP1300EPFCLCD (1300VA/780W),

I have the very same UPS in use, times two. One for Skylake build, another for Haswell build.
IMO, every PC should be backed up by an UPS.
