Configure New PC 7950x or 13900K

<< < (3/3)

I have 13900K in my laptop in form of 13900HX and it does absolutely fine with the microscopic cooling that laptops provide ;- ) Yes it's super loud but that is other thing. And I can run it 170W sustained for hours.

280mm vs 360mm is absolutely meaningless distinction. It's 392cm2 vs 432cm2 in the crudest possible calculation :- ). So less than 10perc. of difference in surface area.
Buy what is available and has good price. ML360 is perfectly ok AIO.

Every AIO will do the same job within +/ 5C degree difference. Arctic is popular because it's one of very few that provide thicker radiator, but every one on market will do ok job.

None of these details will make meaningful difference.

My only advice is to buy good case the first time, you will not enjoy swapping everything, selling the old case, etc. Buy a good, well-sized case the first time and that's it.
And don't underestimate power delivery. Reputable brand with 1000W rating is the right way to go. One thing where saving money is not good idea.

I've just taken delivery of my new workstation. 

It's got the 13900KS (so runs even hotter than the K/KF I believe), I went with the NH-D15 and DDR5 RAM (196GB), I've also got a 4090 in there.  It's absolutely fine in terms of temperatures and I've done plenty of rendering with the CPU at 100% already

Next to it I have an old i9 7980XE and a Threadripper 3990x.  Going off touch alone, the 13900 is the coolest of the lot when they're all rendering.

In terms of power delivery I ended up going with 1200W.

Admittedly I'm in the UK where the climate is nothing like Brazil, but in peak summer my office get's really hot, mainly because I have all my PC's in here, and I'm in a roof space with skylights, so the sun is shining into the office all day during the long hot summer days.  I've not had any overheating issues with any of the PC's.  But I do have a portable AC unit to keep me cool rather than the PC's :)

I understand, I'm going to try to buy a slightly better tower, now you say that the power supply has to be a 1000w one? Remembering that I'm going to use an RTX 3070...
