i9-12900K Temp Question

[bonbons]

Hi All!
First time building a PC and was wondering if these temps are too hot? Sometimes the temps jump to 80-90+ in game and drops back down to around 60-70. Is this normal?
CPU cooler is Noctua DH-15S

Thanks!

I am going to assume you applied TIM (thermal interface material). With that in mind, one of the most common newbie mistakes is to use too much TIM. The purpose of TIM is to fill the microscopic pits and valleys in the mating surfaces to push out and prevent any insulating air from getting trapped between the device and its heatsink. Any excess TIM is actually in the way and counterproductive the most efficient transfer of heat. So the goal is to have a layer as thin as possible, but still provide full coverage over the CPU die.

Also it is the case's responsibility to provide a sufficient supply of cool air flowing through the case. The CPU cooler need only toss the CPU's heat into that air flow. And it is the user's responsibility to ensure case cooling is properly configured and working properly.

So, what case are you using, how many and what size fans, and how are they configured? Typically, you want good front-to-back flow through the case, with slight over or "positive" pressure (a little more air being pushed in than exhausted out).

The 12900k runs like a gpu by default. They will run at as high of a temperature next to 100-degrees if you let everything run as designed. Check the review of it from the main page. Pretty sure temps were high there as well.

Those temps are fairly normal for air cooling. I also see the voltage is 1.25v. Depending on the silicon quailty, it can be anywhere from 1.15-1.3v by default. More voltage = higher temps.

Hi,
Just skip to 1:30 and under volt it

By the way you don't need that much paste

But you can spread a thin layer on both surfaces though

If only there were a +12 year purchase limit for these CPUs until the MB suppliers put a lid on the PLs. Well it makes me smile every time.

I realize now 2 cores I hitting 100c with the best core being 18c lower. It is possible you don't have enough thermal paste or unevenly spread. The cooler mount could be wrong as well. I expect a 10c variation, but not nearly 20c, especially for just gaming with no overclock.

I would remount the CPU and make sure the plastic film is removed from the bottom. Easy to miss.

It looks like the E-cores are running cooler which they always do 71-82. Its the P-cores he's gota get down which are running 84-100.

Seems pretty normal to me. The P-cores on a 12900k do get warm especially if he's using a HSF. Depends on ambient too I suppose.

If your keen matey try do some under volting to get the P-cores down a bit.

Always worth trying an undervolt after redoing the repaste. I knocked ~0.32V off my Max Frequency/Load voltage and it helped temperatures dramatically. Also chose a more stable LLC setting which stopped the voltage rising/falling dramatically on/off load which helped with stability.

This myth has been going on years and years Using too much thermal paste will not matter the heatsink will create a lot of pressure, so even if there is to much it the thermal paste qill sqeeze out anyways, but using to little will cause gaps or bare spots not making proper contact with the heatsink or die

There are a lot of facts proven my statement, look up gamers nexus about thermal paste, and the op hes problem looks like not enough paste or a bad mount and core temps are not even, if you're gaming with a 10900k and getting into 80 to 90+ c that means what i just suggest more then likely, or bad air flow or if hes using a aio or custom water cooling setup maybe hes pump speed is not turned up enough or air flow for hes cas or air in the lines

I currently have a Corsair iCUE 7000x case with 3 fans in the front + 1 fan at the back

Im just saying while 80c is middle ground, having a 20c difference from best to worst core "could" be a mounting issue. 10c is more normal.

Also these temps are just gaming (red flag) and usually not all your cores are loaded fully. If you are getting 100c in games, it isn't a good sign.
