Ryzen 9 3900X Idling at 87 degrees w/ 360mm AIO

[JefeB]

Help! My Zen 2 Ryzen 9 3900x is idling at 85c!

 

My rig is set up in an Lian Li O11 XL with 10 fans: Three 120mm exhaust through the 360mm H150i AIO rad at 1200RPM, Three 120mm side intake at 1200RPM, Three 120mm bottom intake at 1200RPM, and one rear 120mm exhaust at 1400RPM. There's good airflow around the case and the pump in the AIO is set to 2700RPM. 

 

I set the power plan to "AMD High Performance" using the Control Panel, so my CPU is operating at ~1.400v, 4.257GHz.

 

The only non-cooling elements are my AMD ROG Crosshair VIII Formula MoBo, GPU (Aorus 2080s triple fan intake), 4 DIMMS of aluminum heatsink RAM, an ElGato 4K60 capture card, an actively cooled 850W TT PowerCool PSU, two NVMe SDDs, a Samsung QVO SATA SSD, and the fan/LED controllers.

 

I suspect the power plan is the culprit. I'm not much one for OCing or BIOS tweaking, so I haven't changed anything there. Is it the Power Plan or  am I doing something else wrong?

Even if you overclocked a bit it should be that high when gaming not idling. Thermal paste could be the problem. If you forgot to apply it or didn’t put enough on. Or if the pump is broken, try listening closely and listen for a higher pitched noise, if you don’t hear it the pump might be broken. Somethings clearly not right though. I suspect this is an issue with cooling, not overclocking. If you did think it could be the power plan, try turning it off and checking temps.

I used Arctic 4 and if anything may have overapplied. I also shut down all the fans and listened for the pump and most definitely can hear the "whine". Normally with temps like this for my friends, the first thing I'd check is to make sure they removed the protective plastic on the pump head, but none came attached to this one.

This isn't making since. Either it's not mounted right. Or the pump is doa. If your not use to listening to aio pumps. Then the noise you hear could be mistaken. 

 

Also how is the rad mounted in the case?

The rad is mounted to the top of the case with the fans on the bottom of it exhausting though & out the top.

 

I agree, it doesn't make sense. I've tried messing with power settings, cooling settings... anything not BIOS, and it's still running high. The temps I'm getting are directly from the MoBo's sensor & display. When I look at it through iCue's dashboard, it says 31 degrees. Is there a reliable freeware out there that'll help me determine if I've got a bad sensor?

31c water, 85c cpu. That's not right.

Can you use "hardware info" to check cpu temp?

 

1.4v is high for load. But temps should still be better.

Now using afterburner, it's reading 47c. So 39c in iCue, 85c on MoBo, 47c in Afterburner. This is very frustrating.

A bit of advice, Icue is known for showing inaccurate temps

It would be better if you could just use hardware info.

Just post a pic of cpu temps.

 

Also please close all other monitoring software

Wait, so it's your motherboard temperature sensors reading 85°C and not the CPU? 

 

What does hwinfo64 show for temps

Yeah, I'm not sure where to place my faith. I'm hoping I can put my money on Afterburner.

There's only 2 reliable software for ryzen cpu monitoring. 

Hwinfo

Ryzen master

HWinfo64 doesn't have a core temp breakdown. Basically says that it's running fine.

Sure it does

 

Reluanch it, select sensors only, then scroll down.

AH! thanks! It says 47c under 11% load. I'll take it.

After a little lesson in HW, 47c under 11% load. I'll take take over what must be a faulty MoBo sensor.

Looks fine. Now run prime 95 or c20  loop for like 30+ min and see what the temps under load

Thanks so much for your help!

Yep yep
