Question i9 9900 temp to high?

[i99900]

Hi!

I have a 9900k with some high temp at 4.7Ghz at default bios settings. Xmp enabled. I reach 85 C in prime 26.5 within seconds. CPU-z shows 1.2V Vcore at load. This is very high isn't it? I tried to refitt the Noctua D15 Cooler 3 times.
With these temps overclocking is totaly out of the question. At 5Ghz 1.3V i reach 105C easy on most of the cores. Even at 4.8Ghz i reach 95C at 1,250V

Mobo is z390 master. PSU is HX850I

I know the I9's hot! and there is at thing called Silicon lottery. But geez i reach 5ghz temps at 4.7ghz compared to others. Is the Cpu faulty? RMA?

I would try running other tests like Realbench and Cinabench and see what you get
Prime pushes the cpu to really high temperature (for no good reason in my experience)
Have you checked your fan speed settings?
Airflow inside your case?

As far as i know that's normal. Most reviewers recommended at least a 360mm aio for that cpu.
You're also running an artificially created load which is higher than anything you'll encounter on regular use.

I use the prime version without AVX so that i can compare to others. Intel Tun

Yes. I set fan speed to the max. Airflow is also good.
Tried cinabench, Intel tuning utility, realbench. Temps are much better and normal
Its just that i see that others get so much lower temps running prime with the same setup.

Noctua D15 is tested better than most AIOs exept really expensive ones and custom build.
It should manage 5Ghz. But not more.

4.7 GHz is the factory all-core turbo spec, and although few are going to celebrate 85C at those default speeds, it's not really a case of 'defective' cpu, just a case of a 'less than optimal for an overclocker fan'...; you can always live with factory specs, or, risk a delidding, although, unless you have a 2080Ti and a 144 Hz monitor, I'd probably not bother. (I 'lived with' factory clock speeds on my 7700K for perhaps 6 months before even testing it in MCE/all-core core turbo at 4.5 GHz, later testing at 4.7 GHz just out of curiosity instead of need....

My own 7700K only hits 72C (at 25C ambient) at 4.7 GHz on the same cooler as yours, so 85C instantly is rather unusual, IMO. (Maybe your BIOS is overshooting on core voltage? Perhaps you can undervolt even more if your reported voltage is higher than is being read..) However, my temps go downhill quickly above 4.7 GHz, being unstable at 4.8 GHz without a .05V core bump to 1.30V, which then results in 85C at all-core 4.8 GHz....

9900k has a soldered heatspreader. Delidding it would be extremely hard and dangerous and would yield an improvement of only ~4C (according to Der8auer)
So definitely not worth it.

Sounds normal to me with your cooler. Prime will get things rather toasty really quick, as its a massive load, that will never be replicated in real use. IIRC the TDP is 110 for the i9. I tend to think the i9 is better suited for water cooling as well.

What type of water cooler do you recommend?

Well i have seen someone getting better results than that. And it doesnt seem that difficult with the proper tool. Maybe some CPUs have bad soldering and would benefit from delidding than others.

I can get to 5 gigahorses with MCE enabled and AC/DC loadline set to powersaving. Everything else is auto. Temps in cinabench and realbench is here close to the 90C and max 100C. After 14 min i get "BSOD page fault in none paged area" This is a RAM issue. But i cant find something wrong with my RAM setup even with XMP enabled and disabled.
