Am I Experiencing Abnormal CPU Temps?

[B1Lancer656]

I just put my new build together so far but I has been noticing my 5800X3D has been idiling at around 83C with max temps being at 90C while doing tasks. Not sure what's going on or whether or not this is normal??? (And yes thermal paste has been applied). I have 3 exhaust fans and 3 intake.

 

CPU: AMD Ryzen 5800X3D

Cooler: Corsair iCUE 100Hi Capellix

An 83 idle temp is not normal, check cooler mounting (I know you said you pasted, did you remove any plastic film on cold plate?), make sure all fans are operating. Any overclocks applied?

Idling at 80C is way too hot, it should be at somewhere around 40-50C. Double check your cooler mount, it seems like something is wrong with it, either there's a gap between the CPU and cooler that's barely being filled by paste or the plastic sticker is still on the cold plate.

No overclocks and yes plastic has been removed.

I'll double check the mounting in a couple of hours as I wanted to verify it was abnormal. I do know for sure there was no plastic as that was the first thing I removed when setting it up. Not sure what else it could be but I'll come back to this when I get a chance to look it over.

The other possibility is that somehow you got a bad unit that has the microfins gummed up. I haven't heard of any Corsair AIOs doing that, but it could be theoretically possible and would cause this if the mount does seem like it's actually good.

My 5900X idles around 36C-38C. A 5800X3D has 2/3 the cores and threads, so I should think it would be running cooler than that, but then they are both 105W chips.

 

Specs (and preferably pics) would be helpful here. Case, coolers, etc.

 

If you have an AIO with a front-mount radiator in a solid-nose case, that's probably a lot of your problem. Typically, for ideal cooling, you need 2-3 fans pulling in the front, one pushing out the rear, and 1-2 pushing out the top.

My radiator is top mounted and the case I am using is a Corsair iCue 4000X. 3 front intake fans, 1 back exhaust, and the top 2 are also exhaust. This picture probably won't help you at all (was taken earlier) but this is what looks like until I can get a better photo with lights and no reflection

@B1Lancer656

 

I would double-check fan directions just to be sure. A sheet of paper will blow away from an exhaust, and get sucked to an intake.

 

Aside from possible mis-oriented fans, I might venture that the cpu plate is not fully secured, not enough thermal paste was applied, air in the system preventing flow, or a weak pump. Also, feel your radiator and cooling hoses to see if there are any hot or cold spots, or better yet, use an IR / laser heat gun to get exact temperatures. What board is that, BTW?

 

Side note: I originally looked at the Asus B550M-K for my 5900X, but it was strongly recommended I go with the Tuf B550-PLUS or Tuf B550-PRO due to so-so VRMs. And I wonder if this is why.

@B1Lancer656One other thing. I've known automotive heater cores to have a control valve in them that would only allow flow one-way. I don't know if or why the manufacturer would deem this necessary for an AIO, but you might check to see if that applies to this situation, because if the radiator has such a check valve and the pump is trying to push against it, it's not going to flow, hence causing your overheating.

check if both tubes are warm.. if the radiator is warm too. increase RPM on your fans. test if it goes down with max fan speed. 

if it's almost too warm to touch. your radiator isn't disipating enough heat for your CPU. and you would need higher RPM on your fans.. or larger radiator. 

 

your fans blows air up through your radiator unless you have reversed fans. that's most likely not.

Have you checked your Temps with a second tool like HWINFO? HWINFO reads multiple sensor values reported from CPU and MOBO. Check it they are nearly identical.

Have you tried to rotate your case so that air that is maybe in the pump can move to the radiator?

Few things I have done just now:

1. There is no plastic on the backplate or CPU

2. The backplate is touching the CPU as it has thermal paste on it from sitting on the CPU.

3. My BIOS CPU temperature with it sitting idle is about 68C but on desktop the CPU temp going direct to around 80C

4. The AIO tubes have about the same temperature - none are hot or cold

Here are the list of temperature the BIOS gives me:

CPU: 68C

System: 29C

MOS: 35C

Chipset: 41C

[B1Lancer656]

I can also confirm HWINFO shows the same temperature readings with about 80C idle

I have tested this on my tubes and radiator and I can also feel no difference between hot and cold even if I run a stress test for 1 minute.

 

Do you have a stock AMD air cooler lying around for testing?

I unfortunately do not have any stock cooler but I did order a Noctua NH U12s which I hope will solve all my temperature issues on Saturday when it arrives

Is it possible the wrong standoffs could have been used while mounting the CPU cooler?

No. The standoffs were correct.

[B1Lancer656]

Update: I installed my Noctula U12s cooler and my temperatures are running as expected (normal).

That's good. My X3D doesn't hit more than 65 after 10 mins of R23. Something is definitely wrong..

Using the "extreme" preset in FH5, my CPU is averaging about 75C while in the town/city with minimal rare peaks up to 80C. Max operational temp is 90C and I haven't been around that area so I have not received any thermal throttling. About 40C while idle. Again, I am using an air cooler so I'd assume it would be a few degrees colder with an AIO.

You would be surprised. Many people with AIOs don’t get that good of temps..
