First off you don’t need a 360mm rad as a minimum, I am currently cooling my 14900k with a NZXT Kraken 280 @ 288w with a .050v undervolt. I am getting my performance and good temps. Unfortunately my beloved ND-D15s could not handle my 14900k, if I gave it low wattage the temps would be fine but the chip would under perform.
I just retired my NH-D15s to another build because it was not handling my 14900k and put a Kraken 280mm aio. It’s doing great at 288w and .050v undervolt in xtu. Cinebench23 is mid 80’s to low 90’s. Going to keep working on it. You are correct for not settling for less performance, you paid for that chip to serve you.
The 7800x3d is going to age like milk.
Meh, I have one it’s nothing magical.
