By going Eco mode you cut the temperature 30 degrees you also cut the performance a bit but that is the trade off and you can always switch back directly from Windows.

You should also look for a good case with great airflow combined with a big AIO. The Artcic Liquid freezer II 420 is quiet good and yet cheap compared to the competitors. You could also throw a Noctua NH-d15 but from experience I know you will get better results with the bigger AIO, unless you go for a quiet expensive case with superb airflow (fractal design torrent) and cut the margin even more.

Keep in mind that for Intel you need to go for Win 11 to get the best possible performance. You can also play with the settings in Bios to achieve better temperatures but Ryzen is much easier for that. You asked about the difference between 13900k and kf. K is with the onboard VGA while KF is without it. The cpu's should be identical in performance but you always have the silicon lottery part.

I don't know what to tell you about the ram. To be honest ddr4 had ok prices a year ago while ddr5 was 50% more expensive (depends on the market). Now, looks like overnight to me :) prices have been cut in half or even more. ddr5 is cheaper then ddr4 used to be and ddr4 is just crazy cheap now :)

At the end of the day it all depends on your budget and the prices available to you in your market/country. Whatever you choose you won't make a mistake since the performance of both Ryzen and Intel is really close if not identical sometimes ( for our case scenario, rendering, modelling, etc...). Just play with the components, watch some reviews and see what you can get for a good price. Good luck!

Do you think that a 360MM water cooler is no use, does it have to be a 420mm one?

First of all, don't worry about the CPU temps :- ). Let's go over it:

- These CPUs are designed to survive 90+ C just fine. When they reach threshold, they will simply downclock. They're designed this way, to maximize the boost performance, but they will never (almost!) self-destruct ;- )
- They will also always run hot simply because of their architecture. They're built on modern, dense node. The actual chip under the heat spreader is tiny. So the problem with cooling them, has very little do do with cooler on top, and how capable said cooler is at dissipation of heat into space. Problem is heat transfer between the chip (or chip+heatspreader) and the contact area of heatsink.
- And because of that, it makes very little difference what cooler you actually get. Any big-tower like Noctua NH-D15 or AIO kits like Arctic Freezer will do excellently. And since your worry is about living in hot country, the issue would be your room ambient temperature and no cooling system outside of sub-ambient ones (like AC, ICE or Pelter, etc..) can fight that.

So, don't worry about that at all.

Both Intel and AMD also offer easy "ECO" modes that limit the power-draw. There is power curve to these chips where the difference between 100W and 200W can often be <5perc. Negligible. But your chip will run cooler and your room will be cooler too ;- ).

For Intel:
K includes iGPU and has higher stock clock
KF has no iGPU but keeps higher stock clock
F is budget version without iGPU and with lower stock clock

Both Intel 13gen and AMD 7xxx are excellent choices.

For completely new build, DDR5 makes completely sense. Intel + DDR4 is good if you have a lot of memory you can re-use. Otherwise, DDR5 it is.

You shouldn't be going anything below a 280 in my opinion for the 7590x or 12900k. 360 is ok of course and even the 280 Arctic Freezer gives better results then a 360 in some online reviews.

Thank you very much for the tips, the water cooler I was thinking about getting is this WATER COOLER COOLER MASTER MASTERLIQUID ML360R RGB and the case is the Gamer Rise Mode Galaxy Glass Standard Cabinet, I don't want to spend so much on aesthetics, the case isn't one of the prettiest but it looks like It cools well, it is compatible with 10 fans, it fits 360 mm video so I think at the moment it is enough for an RTX 3060 12 GB, but when I invest in a GPU I would perhaps change the case to support larger cards, but My question is whether with this case and this walter cooler support it will be enough for the 7950x?

unfortunately here in Brazil ARCTIC Liquid are very limited, it is not a brand that you can find in any store here, and that is why it is much more expensive than other traditional brands but which are well accepted in my region, I found this one from ARCTIC Liquid 280 but much more expensive than other brands, I'll do some research to see if these others are as efficient as it, thank you very much...
