EK-AIO Defective or 5800x3d Notorious Hot?

[morytox]

Hi, i recently asked about a config for a new Torrent Case because my hardware is running hot.

There i reported temps from Within my Lian-Li o11d and a suboptial Fan usage (corsair QL in Pull Config). Link to other Post

 

That Changed now. 

I ordered myself a Torrent, 3x Noctua NF-A12x25 and a NF-A14 and reconfigured to: 

 

Front Intake with Radiator, 3x NF-A12x25 in Push config.

3x Fractal 140mm in Bottom, Intake

1x NF-A14 in Back exhausting.

 

Flow seems good, GPU seems Happy (leave you to judge).

 

BUT: CPU still getting over 90° in Stresstest? With a 360 AIO and Noctua fans?

See Pictures down below, test ran around 7-9 Minutes, with both Prime 95 and Furmark both in Stressmode...

 

QUESTION: 

Is it normal for the 5800x3d running hot with the stacked silicone on the chip, might my AIO be Faulty?

I am really out of ideas. Do i scramble my head for nothing?

I assume you tried remounting the coldplate/pump? Seeing temperatures are consistently high across the board makes me believe you have an issue with the cooling rather than the chip. Are you running the AIO pump at max speed?

[morytox]

jep i remounted the AIO, applied new Hydronaut Thermal Compound, Checked that mounting pressure is high.

Pump speed is on PWM header, should be maxed out around 70°C. Could still try to leave it on 100%, but i do not know if it is necessary, to leave it on 100% all the time.

Well since they are consistent around both builds, i might think: 

a) AIO is not really taking the heat.

b) CPU is a hotboy...

the cpu isnt really that hot. Its a 105w chip, and without overclocking available on the chip, its as much as it really will pull.\

 

 

 

 

I dont see any sensor for pump speed and coolant temp, are there sensors for those you could check?

[morytox]

I did change pump speed to Full Speed in Bios, still, running Prime95 in under a minute a got temps over 90°C mark... That should not be normal...

No EK-AIO does not have such, Just a PWM and a A-RGB cable, that's it. Pump speed maxes at 2600-2700 RPM (PWM signal)

*Well it Pulls 130 watt when under lode, but still too high numbers for that.

The 5800X3D is not a hot CPU.

 

I mistook the lower power consumption of the 5800X3D vs the 5800X to mean that it also ran cooler. This is obviously a fallacy, as there are other factors.

thats... annoying. Seems like a basic feature for a watercooler, but idk

 

 

 

weve talked about pump speed, what are fans on the aio spinning at?

[morytox]

So snapping up temperatures are sign for bad heat dissipation, not a bad radiator performance. 

This could mean, the pump/coldplatecombo isn't taking the heat or cpu does somehow produce more heat than it should...

 

Pump-Block pressure is checked, also Paste is fresh, 

Maybe just flatness of either component is bad, so there is just no good contact? I even used a very high grade thermal paste... 

 

Really out of ideas..

[Levent]

Do you have another AM4 compatible cooler around that you can test out? Preferably not another AIO.

[GuiltySpark_]

EK's AIO's report pump speed, that's it. It should be steady at around 2600RPM unless its the Elite model.

Fan profile is at 100% with 75°C, As it is NF-A12x25 it should be around 2000rpm

There it goes, should have taken the D15 ... 

no other than AIO, i first had a Coolermaster ML360R, but it had the same issue, so i thought it was aged, or something else, so i switched/bought a EK-AIO, since it got best ratings for AIO's...

From what I heard EK has a relatively good customer service, might wanna shoot them an email and explain your situation to them as well. I am not a fan of water cooling because in the long term they ALWAYS cause more problems, I just ditched mine for a tower cooler and I am not going back. If your issue was persistent across two coolers, you might have an extremely bad IHS surface. If you have a flat surface where you can put the CPU IHS down and shine a light through the other side and see how much of it comes up.

 

I have a metal ruler with perfectly straight edge which I use it for checking surface flatness.

Would that be an AMD RMA than ? (i might want to check).

As far as i heard, Noctua have a slightly curved cold plate to conquer that kind of problem? Which tower cooler R u using?

If you are still within return period I would return it instead of RMA'ing. I replaced PF120 with a Arctic freezer 34 esports duo or something like that. Temps are lower AND I dont have to deal annoyingly loud pump whine, CPU core temp also increases more gradually so that is also a plus. D15 would be more than enough for your use case.

What's your ambient temp?

As others have alluded, yourself included, this is your smoking gun. A 360mm AIO should have enough thermal mass to absorb a considerable amount of heat with only the pump running, even if you had zero fans. So you basically could only have 2 things wrong: a bad mount (be it faulty hardware, plastic under cold plate, etc...), or the pump has failed.

something in the 20's, maybe 25°c ?
21°C outside, small room, so between 25 and 27°c, but i guess this is not the source of the issue.

How is it not hot when run at 130W? Its about same for the ccd temp as running 5950x 250W:s and 3d has even worse heat transfer to the heat spreader.

Well pump has faild, would not explain why temps would go down so fast after turning off prime 95 i checked there is nothing but thermal paste between cold plate and cpu and also the mounting is fine. no idea really.  Do not totally get the saying with smoking gun. (not a native speaker)

Jep i had those ideas as well.

Well my 14 days for CPU have been over. I've tried out too many build possibilities to ensure it is not me...

It hits 85C constantly on reviews with CB r23. It just runs hot when under full avx load. Should not matter at all for the thing its made for, gaming.
