Re: Ryzen 9 5950x running very hot 74C

If your CPU is 60C in idle and 80C in heavy load then it looks like your CPU is not maybe idle.

Can you verify it with process explorer how is your System idle processes and PPT in Ryzen Master while idling with 60C, I would think something must be processing.

Re: Ryzen 9 5950x running very hot 74C

We’ve been through this, Trek. You’re stating what other people were saying in the first 3 pages. Please, read the whole thread and comment after you do that. Don’t mislead people. What he is saying it’s absolutely true, the cpu on idle has those temps. A lot of people have the same issue, and most of these people are certain their cpu is on idle. Just read the thread man, it takes 10 min to go through it.

It's totally possible for your CPU to hit 60C at idle if you have crappy cooling and poor case airflow. But combining that with only 80C at full load, that seems very unusual to me, unless you capped CPU temp to 80C rather than 90C in PBO. Otherwise I would expect any CPU hitting 60C at idle to quickly hit 90C at load.

I was running a 3700x (i know, not quite the same class) with the same cooling and case and was running at 30c during idle. This is with 1-2% usage. I changed nothing on machine except swapped in the 5950x and my idle temps (again 1-2% usage) are at 60+. Can you explain why a so-called more efficient cpu is emitting so much more heat to do the same amount of work (almost none)? Logic would say it should be cooler, no?

 

I should also mention my case is completely open-air right now to remove any other variables, with 6 intake and 3 exhaust fans.

Hahaha. It's so funny that you don't have any proof or arguments and you are doing these no sense questions by making someone looks so dumb or silly? 😂 Yeah we are all probably so silly here and we don't know what is Idle and our cpu was running crazy by having notepad opened and nothing else. So it wasn't at idle 😆

You are really funny buddy. Thanks for making my day at least 😆

Re: Ryzen 9 5950x running very hot 74C

Ero, I understand you might not to believe me, however if you have 60C idle and 80C in heavy load then it indicates that your CPU is not maybe in idle. There were numerous cases where some application, service or other process is continuously running.

It is probably also your case, because if you had some issue you would have 60C idle and in heavy load it would shoot very high above 90C to 95C maybe more.

 

You can use Process explorer application to determine whether there is some application using CPU all the time and Ryzen Master to determine power consumption of CPU in idle.

Re: Ryzen 9 5950x running very hot 74C

i'm with you trek lol , can't read 24 page either , this is too much , every one keeps coming to say "me too" and gives some bricolage adjustment adding to the misleading with possible other problems not exactly the same ... in fact i totally agree 80 at fuill load is absolutely normal for an AIO, so not a cooling problem ... and i fact i just see that the author of the thread did not respond after the first pages ... maybe the problem is solved for a long time ...

and 60 at idle seems ok for "cpu package" reading maybe ... depending of the tools you use to read temps ... or as you say maybe some task running in background, idle for me means cpu usage between 0% and 3% for some time , with a 16/32 core cpu , more than 3% seems not total idle for example and can increase temps , as i see on mine

This why you need to read from the beginning. Most users have nerfed the performance of the CPU via settings to get to where you are commentating on. As the title of the thread says upon initial installation CPU was running at around 74C.

Honestly if the CPU can't run a few things in the background its not working as intended and hasn't been tested properly prior to release.

Re: Ryzen 9 5950x running very hot 74C

@xlox and @trek, i think you might have missed some of my points.

I'm not running a AIO cooler, i'm running a full custom loop with 2 360mm radiators connected to the 5950x only (no other heat emitting sources connected to the loop). The two radiators have a cooling capacity of 1000w+.

When i see the 60c idle temp, the system is idling with 1-2% cpu utilization. On a cooling system with this much cooling capacity, you should see much lower temps.

Using HWinfo, i can clearly see the CPU being fed 1.35-1.45 volts in idle, this is where the issue is. It's generating a huge amount of heat because the motherboard is excessively feeding the CPU power.

To add to this, and to underline that something isn't right, please think about my flatmates scenario. He's also got a 5950x with a noctua NH15 (air cooler) connected. His idle temps are in the low 40s.

Again, we also swapped CPU's and he has the same low temps while mine have issues.

To further add to this, i am seeing the high idle temps and excessive voltage when i am in the BIOS. So not even booted into Windows, the motherboard is pushing high voltages.

Re: Ryzen 9 5950x running very hot 74C

as xlox said voltage is dropping with load, I made screenshot to prove this with my 5950x

idle - 1.5V

load (prime 95, blend, 32 threads) - 1.375V

if you have 1.35 in idle then it means massive load, not idle
