Ryzen 3900x Thermal Problems

[LoneyMakkaroni]

Hey guys . Greetings from germany. I hope that you guys can help me and im sorry for my bad englisch.

 

I just got the Ryzen 9 3900x . I got the 3600x before and the thermals were good. i got an Custom Waterloop with 2x 360mm Rads a quite decent pump an ocool waterblock for my 1080ti and the new hydro X Series waterblock for the cpu. i got the MSI MEG x570 Ace Motherboard and as RAM i got the Corsair Vengeance DDR4 3200 C16 2x16GB. The Watercooling loop is what i run for years beside the CPU and GPU Block. The flow for the loop is good too. Now heres the Problem. I assembeld everything and looked at my Ryzen Master Programm. and The Problem now is that even under a very very small load the temperature is going up very fast. i mean if i start chrome the temps go from 38 to 58 in just a second . if i run cinebench r15 at 3.8 ghz it maxes out at 95 degrees. i even tested that i just press the block down with my hands cause i thought it has like a gap or smth that the cooler doesnt reaches to the die. i even tested the air cooler that comes with it and a cooler master ml240 AIO cooler but there is no diffrence . the cpu goes to 109 degrees and then shuts down. at gaming the temps are around 60C, the GPU is just fine. even after 30 mins of Furmark the temps even with overclocking wont go over 40degrees C. What is suspicious to me is when i run r15 the PPT goes to 130% the TDC goes to 122% and the EDC goes to 90% without even touching the CPU so its on Stock settings i didnt touch the CPU Settings at all. i hope you can understand my problem and im hoping you guys can help me. Im sorry again for my bad englisch and if anything is dont understandable im trying my best to explain further . i did a Photo of my rig but removed the fans just so you can maybe see what is going on . Thanks for your help guys !

Crank up the pump speed?

Increase fan speed?

Check if flow is decent?

Check if the CPU has good contact with the block?

See if radiators are way too hot?

[emosun]

the only thing i can think of off the top of my head is that either the water isn't cold enough , or the cpu block isnt made very well , too thin or too thick.

is the room temperature actually cold?

[caldrin]

Temp jumps seem normal even if just using Chrome or something.. its just the way the new CPUs work.

My 3800x can be doing very little and all of a sudden the CPU usage will jump up and then the temp will go up as well. When AMD released their chip set driver they also had an article that explained this was normal even when using the AMD balanced windows power settings. Its because they wanted t the response times on the CPU to be really fast.

But that does not explain the really high temps  its a strange one really it sounds like you have tried a few different types of coolers and you get the same issue. Maybe the AMD auto clock stuff is pushing the voltage to high you could always try manually setting that lower.. maybe someone can pop along with a better suggestion.. hope you get it sorted.

the radiator is cold just as normal just as the GPU temps. The GPU is 30C at idle and under load max 40C

[LoneyMakkaroni]

the strange thing @caldrin is that before i got the 3900x i got the 3600x and i ran it with the normal air cooler because the waterblock wasn´t here yet. the temps were normal

When gaming my 3800x usually sits around 65 to 75 sometimes spikes a bit higher.. not tried any synthetic benchmarks so unsure what kind of temps i would hit with those.. might give some a go tonight and see.

 

Running an NZXT x62 AIO..

so i ran furmark for a couple minutes now and that are the temps that im looking at heavy load for my gpu. so the loop is just fine i guess. it should because 6x 120mm fans on a 2x 360mm copper rad should be enough

Update the bios and undervolt w bit. Some boards overvolt quite heavily cause the vendors rushed

[LoneyMakkaroni]

i set the cpu Voltage on 1,33125 volts now but its still not better

[LoneyMakkaroni]

i updated the bios and the chipset driver a few days ago

Have you tried rotating your cold plate/water block?

[LoneyMakkaroni]

you mean just rotate 180 degrees?

[bignaz]

Welche Pumpe laufen Sie? Auf was ist Ihre Pumpendrehzahl eingestellt? Stellen Sie einen Spannungsoffset über 0,1 V ein und prüfen Sie, ob Ihre Temperatur sinkt. Versuchen Sie es mit Ihrem Block, damit das Logo unten ist. Die Mikrofinnen befinden sich nicht direkt über den Kernen.

[LoneyMakkaroni]

okay bignaz i will try that thanks

Np. I got the same block and with a single 240 50mm thick I never seen it go over 80c. At 1.32v 4.4ghz all cores I idle at 42c load at 65c.

I have the same waterblock (Corsair xc7) on my 3900x. 3 things to watch out for. 

1) make sure you have thermal paste

2) make sure your block is screwed in tightly

3) this shouldn't make much of a difference, but Corsair recommends having the water flowing in on the right hole and out the left (based on the orientation of your pictures, water flowing in from bottom port and out the top port of the block)
