12900k + custom loop. High 80s / 90s immediately in cinebench. Help?!

[Srius1]

Recently fired up my pc after putting it all together and it’s spiking to 90s immediately while running cinebench. Is something wrong?! Help. 
 

asus z690 prime board.

Probably not. 12900k Is a VERY hot chip. You can check your fan curves to see, and check gaming temps. If they are all fine, then you know its just a pain in the ass to cool

Would help knowing what components you have in the loop.

 

That said, these temps don't really surprise me, the 12900K is an inferno of a CPU.

Specs are in my signature now, I just updated. Also I am on default bios settings so I think asus is going crazy with the voltage. What’s a good voltage and speed to use?

a -20mV offset should be pretty stable, depending on how good your CPU is you might be able to do much more. Leave core clock settings on auto.

Howuch radiator space do you have?

1 360mm

That's quite a bit low for 2 of the hottest running components you can buy. If you can fit another 360 in there that's probably a good idea.

 

That said, only thing you can really do to improve temps is undervolt and maybe swap the thermal paste with something better if its some no-name stuff.

yeah, each of those wants /at least/ a 240 each.  

 

You need more rad space.

I’m using good paste. I am going to try a 1.36 volt and see if it’s stable. It crashed on 1.32

Hmm now it’s only going to 4.9 hz. How can I change this?

Great…playing wz and it keeps freezing mid game…wtf
