new ryzen 9 3900x arrived, unexpectedly high idle and load (over 95°C)

[111Kur]

Hi, 

my 3900x arrived today.
I'm using it with a corsair h100i v1 from which I'm not expecting too much but not those temps. 
Idle I'm hitting 50..60°C. The second there is any load, that jumps to 80°C. Sustained loads get it over 100°C within 5 minutes. 
The weird thing is that these temps drop the instance I take away the load. I turn my luxmark / blender render off and it drops by 30+ degrees (90°C to 60°C in 2s). 

I'm getting these results while locking the clock to 3800MHz and undervolting to ~1.28V
PBO is disabled since I'm "over"clocking manually.

Is this a hardware problem, improper cooling or something else? 

Edit: Board is a msi x570 a pro, most recent non-beta bios. Windows power profile is "balanced". I checked thermal paste and it's alright.

Check mount and check pump for operation.

Can you feel the pump in the H100i moving?

[Haro]

Make sure the pump is working by listening to it or feeling it. 

Re seat the cooler. Re apply thermal paste.

Only use hwinfo64 or/ and ryzen master to monitor ryzen temps correctly.

@ShrimpBrime @Den-Fi The shitty corsair interface reports the pump correctly and changing the cooling profile results in a changed cooling performance (leaf blower mode bottoms out at 98°C, balanced at 101+, quiet makes it a barbecue). As far as I can feel there's vibration at the block but I don't know if that's the fans or the pump. The AIO was working ~10 hours ago on my old system, I only replaced the mobo/cpu/ram.

Are you using Corsair's software for CPU temp monitoring too? If so, use Ryzen Master or HWiNFO64 instead, as those are the most accurate for Ryzen systems.

Also, I'd really advise you do a fresh install of Windows if you haven't already.

My experience with my H100i is that the backplate and mounting screws (screws have extra piece on it that rotates freely) are a problem with correct mounting.  Reach behind the block between the board and the block and see if any of the 4 mounting screws have any wiggle room in the "free moving" portion of the set screw - if it moves its not properly secured, if its rock solid to board then the standoff is on correctly.

for the love of god stop running the system under load when you see temps of 90+ and remount the block to ensure proper seating.

Make sure as well you took the protective tape off the bottom of the pump if its new, and or that the thermal paste isnt dried out if you didnt reapply the stock paste. That very much sounds like either a bad mount, bad pump, or bad paste. Since you crossed the pump off pretty well then move on to the other two.

@Mateyyy I got these temps from ryzen master, although I'm now checking through hwinfo, too. 
The corsair software only gives me some temperature somewhere in the block which was always off by sime degree. (it self-reports as 54°C right now but usually rises slowly under load. Coolant maybe.)

take off your cooler, wipe your cpu and aio with a cleaning rag, then reseat your aio and make sure it is on tight enough. from my experiance with an overclocked r9 3900x these temps are like 10-20 degrees too hot. or, it might be because of summer heat. when it is hot in my home, i experience similar temps

Is the bios up to date?  

[111Kur]

@Tristerin as far as I can see, the pump is mounted correctly. I did take it off and reseat it just in case before but that didn't change anything. It's not mounted using the 4 screws like the newer versions / Intel versions, but uses the AM4 "clamp" system. I did push the block against the cpu and tighten the screws progressively though to get it as centered / evenly tightened as possible. 
@Atmos this is not a new cooler and I did apply new noctua  NT-H2 paste so I should be good there. As for mounting see above. No obvious errors I could see. 

[Tristerin]

Odd my AM4 bracket is the 4 holes, GTX is the V1 version I thought (I have GTX) - guess I was wrong!

@eeeee1 I have ambient at ~35°C right now, would this be an issue? Shouldn't it still be closer to coolant temp than that? It's not really that useful of a pc if I can't use it in the summer... 
I can't really tighten it further without it being uncomftably hard to move. 
@TofuHaroto did that and I'm fairly certain that the pump is working, although it's hard to check by ear with the fans.
The bios is on the latest non-beta build. 
@Tristerin the older ones had the clip thing. I think it's actually AM3 mount but am4 boards are backwards compatible or something.

All I have left is that there might be buildup in the loop but that would have been noticable before... 
I might try the wraith that came with the CPU for comparison or something... 
Could this in theory be a problem with the motherboard or CPU?

that is a fine temp. you dont need to tighten the cooler that much.

Nope for the most part.

Try the wraith cooler.

(ambient as in the room temperature, the cpu is still at 52°C with chrome and a bunch of diagnostic windows open).

that temp is fine... you might be asking too much

[Tristerin]

Next step - You have an air bubble trapped in the CPU block.  Turn pump on full blast and let it run for a while, then pick up the machine and orient it in every direction possible sans the block ever being above the radiator or highest point in the loop to get that air bubble out of the block.

@Tristerin the pump is at the lowest point of the loop atm, would this still be reasonable? (radiator mounted at the top of the case)

@eeeee1 The thing is that it's 52 at virtually no load. I want to be able to run a render or game in the evening without it triggering thermal runaway or the cpu giving up on me in a year. Would I need to get better/different cooling to get below 95 loaded at 30°C ambient?

i use google chrome at like 50-60 degrees and my cpu is fine. to my knowledge i have never gone over 85 even under a cinebench load. you could try raising your fan speeds. mine are adjusted to ramp up faster.

Best place it can be for an AIO.  However doesn't mean its not trapped, which is common.  Since its a V1 I would expect you bought this used or have had it for a while so it may even have more space for air after some slight evaporation in the loop over years.  

 

Put pump on 100%, let it run a while.  This may push the air bubble out itself.  However I have the most, and quickest success, when I run the pump and then pick up the PC and literally go through a sphere of movements without ever putting the block at the highest point and use gravity to assist in removing the bubble

@Tristerin you're right, I bought the AIO when it the hot new thing and RGB was still somewhat cool. 

You were also right with the bubble it seems. Idle temp sat at 45-48°C which is still not great but 100% load started at 70°C and now that it's running for 30min got to 84°C which is OK I guess.  Thanks for the suggestion, I would never have thought to turn my PC weird angles.

A followup question anticipating renders longer than 30min:
What would a better thermal solution be, considering that I might run 100% load for multiple hours? I know a custom loop would achieve this but I think at that price point it would be more viable to rent a commercial render farm...
