95c on full load on a 360 is a miracle. Every review I watched on YouTube it immediately shot to 100 max throttle. I suppose the undervolt saved the day?

Yes 100% true undervolt keeps it under 100℃. Here is the real reality of just using the CPU if you do not change stuff.
Both my 14900KF can do 400Wats trying to compete with RTX 4090.

And that's with the 100 cap? What if you unlock it to 115 will it hit the ceiling?

Truthfully I thought about it and to see how far it will go,I read it tops out at 438 Watts. I will test it out and see if I can hit RTX 4090 600W levels

Deactivating hyperthreading yielded 5% better ST scores on my 13900ks.
That should get you over 1000 points for the screenshot

Have fun !

Not trying to be rude these were just normal test on normal settings,not going for the highest scores. Of course I can get over 1000 on CPU-z

Did you try to undervolt it ?
Probably you can go much or less under 1.35V, so this would reduce temp/watts.

Well it is undervolted from default using offset CPU voltage.
I am going to assume you mean a manual voltage with straight LLC setting that does voltage 1:1 then yes I did.If you mean something else please let me know the BIOS has many different ways to under volt.

Or are you just refering to the 400Watt screen then if you are that was on purpose to see the wattage on an overclock.

Yes I mean offset and LLC.

Well the CPU are new and default settings hit 370 watts out of the box. I will be doing various overclocks but for now I settled on the 14900Kf to run
all P-cores 6000Mhz with boost to 6300Mhz
E-Cores 4400Mhz
Ring 4800Mhz
Set TVB if any temperature hits 90 to downclock.

14900Kf 6000 Mhz+ Cyberpunk Style

Thought you may find this interesting
Opps 14900KF Forgot I had LLC 6 on Asus Board 475 Watts before downclock and no crash lol.
Had Temperature set to 115℃ and was seeing how many watts these 14900's can use.Just using AIO 360MM maybe need chiller or phase change .

U guys need a triple rad like me if you're doing this for fun

 

[gerardfraser]

Someone will take the screenshot to serious and be another nut on the internet with all kinds of crazy.These PC parts are for fun and entertainment

I’ve got a 420mm on my 14900KF. I think I’ve seen it peak around 102 on a few cores while Priming, but mostly stays around 90 during Prime.

General usage the 420mm keeps it fairly cool. Loving this setup so far…

That's just 32% more power for 4% more performance compared to my undervolted 13900K. These top-of-the-line CPUs are overclocked out of factory and very long past the point of diminishing returns.
