Sudden high idle temp on 5800x

Something is going on here, I'm sure. That Noctua should be enough, especially considering your load temps are ok.
Personally, my next move would be full Windows reinstall. Something is causing it, I don't believe it's hardware.
The 5600 will surely do you fine if you cba messing about any more, though.

Im leaning towards keeping it. Maddeningly the temps seem more respectable now, everything is back to stock and it seems to be around 40 ish now on desktop. Driving me bonkers.

Im calmer now I found the AMD bumf that confirms being at 90 is expected behaviour by design, just not used to it. Must decide now if I want an albut silent system with a 5600x or trade off silence for performance

I also noticed icue is a big culprit and closing it dropped temps but oddly reopening it and letting it run didnt cause it to sit back at 60.

Are you sure the fan is on when it's idle?

Good point, fan is definitely on.

Ultimately my cooler, a U12s, is rated for up to 125w ish and at full tilt the cpu is pulling in 135w at least.

Im tempted to pop it back into 95w eco
 
Cheers dude. Will give that a watch tonight.

Ultimately I dont think my cooler is up to the task. That said desktop temps are 40-45 and its behaving more in line with what I would expect. Perhaps it just needed a few hours for the paste to cure a bit or something.

Going to keep the chip. Next step will be to see if I can pick up a used Noctua D15s as an upgrade I think
 
Even with great cooling they run warm. From what I've ready it's down to the very small surface area and having one CCD with all 8 cores enabled. The 5900x has 2 CCDs so double the area to transmit the heat to the cooler but only 50% more cores so it doesn't run as hot.

So, seems the cpu is running as intended given my noctua is classed as ‘entry level’ cooling which is fine.

I now have a decision, accept it’s a hot chip and the fan noise that comes with it. Or switch to a 5600x.

Your idling hotter than intel CPUs on load.

Think I just have to accept ‘hot’ is my new normal for now for a bit and that is fine as it’s designed to be hot
 
there was something about a certain monitoring software that caused the cores to not sleep hence higher temps but actual load was very low. have you shut down all monitoring software and used something like hwinfo to check temps?
 
I used some settings suggested by Joxeon to set up PBO.

PPT 125 TDC 84 EDC 125 with curve optimiser -25 all core with a 0mhz core offset.

What are your idle and load volts?

This is mine using the above settings.

The idle volts do fluctuate abit and does go up to ~ 0.850v.

EDIT

My temps are ~ 27c idle and ~ 65c load but am using a 360mm AIO.

Very nice mate. Will have a play in the week. On the verge of getting a Noctua D15s as an upgrade.

Something is definitely going on here. God a few programs opening, got cctv viewer running and doing some light desktop work and the cpu is at 42. There seems to be no rhyme or reason yet Meanwhile earlier just being sat on desktop, nothing additional running and no activity form me it was sitting at 60

Some versions of Windows like to download and unpack updates ready to rollout. If you have a home network especially that could be what is going on.
 
Ill take a look at that cheers.

Ive another 16gb of ram coming today, so will in total have 4x8 (32). Hope having all four slots filled doesnt magically push my cpu over the edge!

Prime/Cinebench 100% all core load?
 
I'm cautiously optimistic I found the culprit. 'Qfinder'. The qnap app for finding nas drives on the network. DIsabling that put my cpu on desktop down to 35-39c. :mad:

Edit: Nope, after and hour or two bobbing along in the low 40's with chrome open watch netflix its now solidly low 60's at desktop. FML


EDIT: After some further testing and rummaging on the AMD pages, seems culprit is definately iCue. Completely removed that and desktop temps are mid 30's.

This is my ClockTuner results with PBO on Auto. Not bothered about running Prime as my system is stable doing everything i want it to do. ;)

Nice one, hope that is sorted for you once and for all now :)
 
I think curve optimiser -15 worked for me, if you want to get temps down further.

As you've found out, anything which maintains a single core load will keep the chip in a state where it will attempt to use PBO for single threads which is something like 1.5v. Which is made worse on the 5800X because of the concentration of heat on the 7nm die.
