3950X Cooling issue

[GM Rod]

Alright guys!
Just got a 3950X.
I tried to follow this guide to setting it up:
>LINK<

Everything goes well, until I try the 4250 speed on Ryzen Master. It does the stress test and powers off.
I know why it is, it's the cooling. As soon as it starts the test I can see the temp go past 100.
So then I need advice on how to improve my cooling, I guess!

This is what's in the PC right now:
>LINK<
It's idling at 77 C right now, and one Cinebench test pushes it to 92 C...
So my suspicion is that this cooler is underperforming since it's old (like 5+ years old. I bought it back when I built this PC back in the 5820K days).

Now I've heard other people are having issues trying to use the h115i with this CPU.

 

What should I get to replace it then? NZXT?

 

Thanks in advance!

Probably the pump is dead - that's way too high idle temp (as well as load temps) and it starts to throttle. It's not that this cooler is insufficient - yours is just old.

Right, that was my suspicion. Ok then. Any suggestions on what to get to replace it?

any good aircooler should beta that 240mm rad even if it was new. like dark rock pro 4 or NH D 15

It's a 3950X. I think it deserves an AIO. I'm gonna try to OC it too... So maybe a 360 one?

What kind of pump RPM are you running? I found that leaving the pump on a controlled header caused thermal issues like that, so I always run my pumps at 100% speed. My Old Corsair H60 (1st gen) did ~ 4000 RPM or so, by HWiNFO. My H110 looks like it's ~ 1500 RPM.

 

Possibly these i units removed the motherboard control. I had a H100iv2 for a very short amount of time.

Alright.

 

So I bought a Kraken Z73.

Installed it today, and it improved significantly.

Instead of 77 C, it's now idling at 60.
And it only jumps up to about 80 when cinebench is running. Instead of 92.

Even got a higher score now. 8727.

 

Still too high, though, right?

So what do I do here? Is it my case? Should I mount the rad on the front instead of the top?
Dark Base 900 is quite modular so I can literally move anything anywhere... help!
Here's how it looks right now, with the side door removed:

Also interested in this.. I got a 3950x a few months ago and have an H115i w/ Noctua fans on it. Generally idle 50C-65C (this thing can jump 10-20C while idle) and I'm new to AMD from Intel. Definitely something wrong with my H115i sometimes because percussive maintenance can drop the temp if it's idling like 70C+.. custom loop is coming in later this week.

 

Does this chip just run super dang hot? Custom loop is going to have at least an EK-CoolStream SE 480 on the CPU. Worried adding the GPU into the same loop would actually heat it up as it normally idles about 33C (Asus RTX 2080). Also plan to try and recycle the radiator from the H115i (because it's so dang inconsistent I accept the entire thing might just be screwed if I cut the built-in hose).

 

Thanks in advance for any advice. Happy to post more specs if anyone needs them but very curious about this processor.
