5900x running very hot

image_2020-12-27_020923.pngHi! 

I've build new system with 5900x, gigabyte x570 master and z63 for cooling.

But my 5900x is running around 70 in idle.. I am no expert, but i think that is a lot for watercooling. I've set pum to max. 

Bios and drivers all have been updated.

What can be done to lower temps? 

My previous 2700x (with same z63) was running 35-40 idle

 

edit: it turns out that those numbers were while downloading game from gog.com.. Right now 43. But I am still Thinking that 70 just for downloading kinda hot

Wrong

 

Check your usage before you post online

Re: 5900x running very hot

Ok. Right now I have 13-17% usage with 67-70 temps

Pump running on max, pupm fans at 70%

Is it normal?

Re: 5900x running very hot

Which watercooling are you using?

If your cpu is doing 13~17% at idle, you should check for malwares.

Re: 5900x running very hot

NZXT Z63

well, it was not idle, it had some download on background

Example: I'm playing ESO, usage around 15%, temps 70

I do not think it is malware - it was clean install. And from the start that kind of behaviour

Could it be - small amount thermal paste?

You should try the negative Vcore offset.  Try 0.0500V~0.1000V offset.

It will definitely lower the core temperature.

Re: 5900x running very hot

what cooler?
what thermal paste?
is it built correctly? = remove cooler, clean CPU and cooler, add new thermalpaste, put cooler back on

Re: 5900x running very hot

the 5900x runs really hot.. i have a similar water cooling system but with 3 fans and if the computer stay at idle for like 10 minutes i get 38c but if i open a webbrowser or something it jump to 50-55c
And when i do gaming it easy jump to 77c or even 83c at max.
When your cpu run at 70c then something is very wrong.. Try and grab your cpu cooler and see if it sits loose or if its tight.. also you only need to appy a tiny amount of paste when you install the cpu cooler.
And check hte manual of your water cooler it actual does matter how you turn the cpu cooler and how the water pipes poossition.
I found it usefull to remove the side of my computer ( its made of glass ) to let the heat out thet inside of the case simply get super hot.. one reason is that my case the water cooling is in the top and there is not much room for the air to exit the case so it kind of get blown "down" into the case instead of out.
I will create some holes in the top of my case manualy ( remote a plate or something to bypass this.
( heat rices up )

tip you can in bios adjust the fans speed ( profile ) so they spin faster at x temperature, in general i think you should run at about 950rpm when your computer is idle and max when its above 75c. Then create a nice curve and apply.

Its a really great cpu but its not okay for AMD to release something that is hard to cool with ordinary hardware it create tons of issues and instabilty.

I like to recommend that you maybe consider to move your water cooling to example the front of your case where many cases typical have big fans that can help cool.. its not ideal  but acording to some tests it will only make your case a tiny bit hotter 1-3c.. And ofcourse install 3 fans in the top of your pc to blow hot air out in the top  ( hot air rices )

tip after you update your bios, then do a Restet to factory default just to make sure any changes are set as default els that can create issues as well.

Re: 5900x running very hot

Ok, noob question how to make negative Vcore offset)? or any video explaining how)? Will it influence performance?

On the other questions:

It is build the same way system on 2700x was built - and it never reached above 65

As for cooling I have 011 xl case with

3 fans side intake

3 fans bottom intake

2 fans top aio nzxt z63 outtake

1 fan back outtake

I was thinking to switch to z73 aio, but as far as i saw reviews, it is not that big of a difference.

Interesting point: i saw amd statement in which they've said that cpu running up to 85 is "completely natural phenomenon". What are your thoughts about that?

Re: 5900x running very hot

According to AMD, your temperature is perfectly normal.  Nothing to worry about.
