Throw in the towel on water cooler for 3900X?

The pump will go in the bottom part of the case by the hard drives, and likely I will need a different power supply with super sleek cables.

I’m not really going to have room for a res, unless I had it above the CPU.

Also, know anything about watercooling a Grid K2? Otherwise I plan to have it air only, as in the diagram.

Also just for note, the H100i is fine again. Lel.

Nope, not sure. And I’d make sure you can get waterblocks for those other cards on the bay before you start the process. The 970 should be easy, but the 480 is old, I’m not sure it’ll be easy to find one for it.

Well the vrm on this particular board is actually pretty poor.
So that could also be partially your issue.

Well, in all fairness, those AIO pumps tend to like being run closer to their max.

Your definition of “bad VRM” and other people’s definition of bad VRM tends to differ significantly. You have the highest of standards lol

Well yeah a 4 phase vcore vrm with doubled up components per phase.
With those not so great Onsemi 4C010N and 4C06N discrete mosfets…
HW unboxed also tested a couple of x570 boards vrm performance,
with several cpu´s like the 3900X.
And that particular test also shows that boards like the Msi x570 Gaming plus were not really capable handling a 3900X very well.
They actually failed the test.
And those particular boards use slightly better Onsemi 4C029N and 4C026N´s,
i believe out the top of my head.
So that his particular board is having issues with handling a 3900X,
does not really suprise me that much honnestly.

On stock settings it should be okayish probablly.
But a 3900X will definitelly push that vrm to its limits when,
puting some heavy workloads on it.

oh shit, only 4 phase?

uhh yeah, that’d probably be stretching it for a 3900x.

Yeah only doubled up components per phase.
But those mosfets themselfs aren´t particulary great either.
I’m not saying that his issue is 100% board / vrm related.
But i do have to point out that the 3900X with that particular board,
isn’t really a great match so to speak.

The thing is that I have a similar issue with my 3900x and I’m on a Phantom Gaming B550 itx something or other. I picked it because it had good VRM for an ITX. I think the 3900x was just an autistic CPU.

I know it isn’t a great match. I have turbo turned off and have no issues.

I plan to replace the board soon with a nice X570 board, but I’m also waiting to see what the next chipset will have and thinking about a 5900X if I have a series 1 3900X.

One thing at a time though.

It was built for what I’m using it for, and nothing else. The IO die is specifically just good to have as a separate unit rather than integrated into the CCX’s.

I have no desire to run “Normal” spec lol. Gotta hab some BEEFB

It could definitelly also be just a bit of a bad batch 3900X cpu as well.
I believe there has been a pretty poorly first batch of those chips yes.
Same was true for the first 3700X chips i believe…

I bought it when the XT came out, so I’d think it’d be fine. Off newegg and all that.

Yeah, having the cores for cross compiling arm stuff is really nice.

VFIO and VM stuff, some big data stuff like repo management / surgery, then fast small data with paralell compiling.

Its a sexy chip when used correctly. Course the same is said for a gigaccel x8i but… who has those now

Maybe you could try an air cooler.
And maybe you could place a dedicated fan towards the vrm area.
Normally a 3900X should do pretty fine with a good enough aircooler really.
Those clc’s can be a hit or miss.
There are definitelly some pretty good units out there.
But if you have a good airflow possible case.
Then i think that Aircooling would perform just as well as most clc’s out there.
Of course custom loop setups are a bit of a different story.
However in my honnest opinion i don´t think that custom loop systems,
are really worth the investment for a mainstream system.
In regards to Threadripper that’s of course a different story.

I have somewhat a ridiculous demand when it comes to cooling my PC actually. I hate having the room BAKE in the summer, so CPU temps basically being halted at 65C is my big goal. With just video editing, linux code work, and games, my current setup does that fine. I want better later on tho. Maybe even have a peltier involved.

Because I can really at that point.

Of course nothing wrong with getting a new clc either.
I mean there are definitelly better units out there then your old H100´s.
I’m personally not a huge fan of clc’s mainly because of the additional potential pump failure.
However units have become a lot a better then the H100’s and H80´s of the time. :slight_smile:

And of course my personal preference doesn’t really matter much at this point haha.

Well really what I want is for the system to be per-series upgradeable. I’m not gunna get GPU specific coolers, I’m just going to get generic ones that will be intercompatible, at least if I can. I want the case, cooler, and drives to all be one whole unit, basically.

If its possible to have a peltier in a water loop, I’d totally do that and hold CPU at like 10. That’d be great. Then I could OC and not really give a shit, that’d be great.

The hero we need.

The 3900X doesn’t require water cooling at all, in fact there have been several reviews pitting the stock cooler that ships with the 3900X and a AIO cooler, turns out there’s not much in it, around 100Mhz in it and that’s within margin of error. I’ve been running a 3900X (on a MSI X570 Unify) with a Noctua NH-D15 for some time and it’s super quiet, even under heavy load. If you want a HSF that’s a little more “stylish” then maybe a BeQuiet!
