Hi people. I just installed a 5800x into an aorus x470 with new bios and chipset updates. I have a corsair h100i AIO and am seeing really high temps idle is around 60 C and getting to 80-91C in games. On IQUE I see around 40-55 C. I run everything on extreme being the fastest fan and pump setting to try and help. I continue to see 80-91 C on HWmonitor though. Any ideas as to what is causing this. Which do I trust, corsair or HWmonitor ? I used the corsair tmx50 thermal paste and applied a generous amount to it. I don't believe that is the problem but I could check and re-apply.

Any help would be appreciated

-Thanks
 
Solution
Applying more thermal paste than necessary will degrade the thermal transfer properties. You only need enough to fill the tiniest of voids. If any paste extends beyond the CPUs exterior then it's too much. If you do decide to reapply your TIM then use Thermal Grizzly Kryonaut.

The H100i is the minimum 240mm rad for cooling a 5800x and would just cope without any Overclock.

Another cause of excessive heat is the thru flow inside your case and can make all the differance.

Describe your setup, the number and size of your fans.

Use HWinfo64 as another comparison (Do not use two temperature monitoring apps together) and stress test the system with AIDA64 to check your Thermals and Rail voltages under load.
With AIDA64 run the stress test...
What settings?

I'm not sure how you're assessing performance. Ryzen's way too dynamic with clock changes to look at clocks in utilities and infer performance at all. The only way to do it right is use a decent benchmark; cinebench 20 or 23 are very good. Do both multi-thread and single-thread; single thread is most important for gaming performance.

Many of the internet hacks for lowering temp are effective at that and may not hurt gaming performance if done the way they say but they can limit multi-threaded performance. Some (like the conventional all-core overclocking) might not hurt multi-threaded but can really kill single threaded.
Boost override, PPT, TDC,EDC. If you are really interested it’s in the video flayed linked in this thread. It’s a pretty good video. As many people say not to get the 5800x because of the temp “problem”. He basically said to change ur settings to his based on what cooler you have. I did so and it seems to be helping a bit. I am just scared of seeing 85-90 C because I don’t want my CPU fried you know.

His method is tweaking the PBO settings to lower temps a little. It doesn't hurt performance (much) but run Cinebench tests to know for certain as every CPU has uniquely different silicon, and every motherboard different setting biases from the mfr. Do it in a controlled fashion.

And again: 85-90C is within the temp range the CPU's are designed and expected to operate. AMD has said so. It's not the CPU that's stressing.

Ok so I’m fine to keep it stock and not worry about anything. I mean my cooler is pretty decent being the H100i Pro. There’s not much I can do really. I mean how much of a difference is Kryonaut paste gonna make if I were to get some in the future.
 
How about this then?
The 'problems' with the 5800X in particular lies under the hood, or the IHS. The cooler can do nothing when the 'side effects' of its little quirks don't reach it.
The 5800X is the only one out them that exhibits such 'volatile' behavior. You are one of many with concerns about this cpu:

Kryonaut is terrible for that cpu, unless you're ok with frequent repastes.

"Kryonaut uses a special structure, which halts the drying out process at temperatures of up to 80° Celsius."
The stuff 'burns out' faster with elevated thermals.
 
I have an NZXT H500 with two case fans one being an intake and the back one being an exhaust. The Room temp is 68 degrees Fahrenheit so it is taking in a decent temp. It is also on my desk. Then just the h100i. I think it's a decent amount. I had no trouble with my old 2700x granted it didn't draw that much power compared to the 5800x so I don't know the issue. I will do the stress test and upload a pic soon.

IMO the H500 is not conducive to good thermals with the 5800X and any fan upgrade to 140mm for exhaust should be considered.Also the 5800X runs hotter than the 2700X

Although your Max temps at the t/die under stress testing are more than I would feel comfortable with (if consistent) however you would very rarely stress the system thermals as AIDA64 has and after 20mins you are OK. Thanks for the upload for analysis BTW.

Remove the case front panel and point a desktop fan directly into the case and see if temps are reduced at all.

Do you run a none reference GPU.? Overclocked none reference cards will increase airflow temps considerably and larger exhaust fans would help dissipate hotspots.

A quick tip regarding Overclocking the CPU.
Try for an all core Overclock and disable turbo boost which will reduce thermal spikes.
Also ditch Ryzen Master for Overclocking and just use your Bios.
