High CPU temps under load

[MySQL]

Hi,

 

I bought new CPU i7 7820X and I am coolig it with NTXT Kraken X52, problem is when CPU gets uder load or if I try Aida stress test, core temps jumps out on 70°C  in second or two (it is far from TJ, which is 99°C I think). So my question is: aren´t those too high temps on AIO, I thought it will be cooler... I didn´t Overclocked it, everything is set to auto in UEFI, I´ve edited fan curve and pump curve but it doesn´t seem to make something better (maybe my curve is bad, but I really don´t know), but I don´t won´t to damage my new CPU.

 

Thanks lot for help.

That's by design though  

 

And Hi.

By desing?  so no problem whatsoever? I know it´s 16core which is little bit different from 8 core or others, but still 70°C... I don´t know

Oh you have a post now. When I responded, all it said was hi  

 

But yeah, the problem is A: high core count, high TDP and B: Toothpaste between the IHS and die. You can have a baller CPU, but if the transfer between die and IHS is meh, temps won't be amazing.

well  nevemind you have to start somehow

 

Toothpaste oke we can call it like this , well I used stock which was applied on AIO Pump (NZXT comes with Themal Compound) but I have Arctis MX2 I think, so I can change it, maybe then it will be better? I was thinking about bad contact with CPU die and cooler but it screwed tightly in place...

Yup, that's entirely normal.
My 6700k also jumps from 30°C to about 65° within a second as soon as I put it under load, even tho I run a custom loop.

Toothpaste is better than you think...

No it's not, it works for about 5 seconds

well if it´s normal then, yeah i saw JaysTwoCents video about using different compounds (things avaliable at home) but thanks lot i don´t want to use toothpaste better Thermal Compound

Depends on the toothpaste I guess.
Brian from TechYesCity got different results.

To get rid of the toothpaste you have to delid the CPU, that is take off the metal IHS (which you normally put paste on), remove whatever's on the die, put your own thermal paste, maybe glue the IHS back on, then apply paste on top for the cooler. This will void your warranty mind you.

 

Also, 7820x is an 8 core.

That's Aussie toothpaste m8.

so 70°C under load even with AIO are ok?

I don´t want to delid it at least for now  I don´t even have proper tools for it, yeah it is.

ok so if this is ok even with AIO then there is nothing more I can do maybe changing Themal Toothpaste between AIO and CPU. Thanks lot for help

you could also try drop the core voltage (Vcore) and CPU input voltage (Vccin), since you arent overclocking.

yeah that is possible way to reduce temp, but if 70°C is Ok as I sad under load in Aida stress test that I leave it as it is  probably, Once again thanks for help

Aida is hardly the most stressful one though. Give Prime95 a shot and you'll see

I didn´t heard about prime95 it´s stress testing app too as Aida? or something like that

it's not built as one, but it works well as one. They even tell you what settings forces most heat and what settings forces most power draw

oke so after I get back home (after work) i give it try  

[MySQL]

ok so i´ve runned Prime95 test and CPU temps got arround 82°C and 83°C so is it bad or not? Prime stoped with no errors or warnings (in that windowses which it opens)
