There is the results from IPDT test
...i9 14900k, you know, when i bought the i7 13700k i was also surprised that water cooling is almost futile, and it can NOT keep it under 100°C at default settings = no power limit (it does max out at about 280Watts witnout OC)
NZXT Kraken 360mm is not good enough, i run double 420 rads with Watercool Heatkiller IV Pro, and it still can't keep it cool, but for few minutes the CPU can run at 250W and not reach 100°C, but rather 90~95°C.
One 420 rad is bigger than your 360, on top of that, mine are 50mm thick.
What is the thickness on that Kraken 360? 35mm?
You said "I have checked the cooler is mounted properly" , and i can tell you, that you may think that you did that, but in reality, there is a like 10µm bigger gap on side, and that makes the temperatures go higher than expected.
Hint - use XTU to limit TDP to 120~150Watts, the 12,13 and 14 gen run at that TPD with optimal speed, anything more and the gains are so little, you won't even notice.
Yes, you won't be able to use it at 'full power' , but the question is, was that CPU ment to run at full power in the first place?
At room temp of 20°C and if i let it idle for few minutes, the idle temp will be about 28°C, i assume you get the same idle temp.
Now at default settings, which in my case should be 250W, the cooling for a short period of time is good enough to let the mother board run higher than 250W.
The thermal paste i use is Noctua NT-H2 , it is i would say bette than kryonaut, at least for me it is, bcoz i get higher power readings with it, as opposed to max 265Watts with kryonaut.
Yes, it takes few minutes to find out if the cooling block sits perfectly on the CPU.
It does not really matter how i spread the thermal paste, what matters most, is how well the cooling block sits on the CPU!
And if it is just the memory stress test for 1 minute, the temp will not reach 100°C or in other words, there will ne no thermal throttling at all:
The max TDP i can run continously is 230W, this will never trigger thermal throttling.
Run the memory stress tests yourself at various TDP limits, to find out, what is your water cooling capable of.
As far i know, i9 14900k easily does 350W without OC on default settings.......and you try to keep it cool with a single 360mm rad.
BTW, for the test you see on the screenshots, all fans on the 420 rads were running at bare minimum, bcoz there is barely any difference in fan speed....bcoz the colling block on the CPU releases water, which is NOT warmer than 50°C, it's the CPU that is horrible at transfering heat to the cooling block!
Get yourself at least one MO-RA3 420LT radiator, if you plan on actually using almost the full power.
