Hi all,

I've been thinking about moving to a WC set up for a while and finally decided to start chosing components. Currently my plan is to only WC the CPU as a start and see how it goes. I'm confident enough with the build process itself but a little unsure when it comes to components. As such, I used the EK build function to come up with the below, modified slightly myself to have the flat 120 reservoir instead of the suggested one.

Are there any glaring mistakes in the below setup? Would appreciate any guidance on potentially better (or better value) configs as I'm totally new to the process.

Cheers

Jon.

Coolant wise im assuming you'll be mixing it with your own clear coolant such as deionised water as you have a concentrated coolant there that needs mixing, not a premix bottle.
 
finally have you measured and done a mock up of your runs? I have a feeling you'll probably need some angled fittings, offsets, spacers etc as well to make things easier.

Also a drain port fitting needs to be included for the drain port on the res.

If the Res is not the lowest point of the loop i would suggest a T fitting and installing drain port there as well, trust me it makes draining so so much easier.

Like So:

Due to the way the Res is built inside, its separated inside so its like a dual compartment. so having a drain port there is not essential but helps without making a mess.


Something like this to stick with the theme

I chose the standalone Res and pump as my idea was to have the Res on the rear 120 fan fitting and have the pump elsewhere, probably other side of the case lower down. Will that not work? I might need to post a pic of the intended layout as I'm prob not explaining it properly.

You don't really need this: EK Water Blocks EK-ATX Bridging Plug (24 pin)

As you could quite easily do it with a paperclick inserted into the 24pin cable.

I did not know that! Thanks.

Yes, to be honest the build tool wouldn't let me progress without selecting some coolant so I just chose the white to match existing fans and 3090 lighting. Not really decided yet if I want to go clear or white.

Also not entirely sure why you need this: EK Water Blocks EK-Quantum Torque HTC 12mm Fitting Colour Pack (10 pcs) - Black

Your fittings already come in black.

Ah so the parts all come with fittings? Good to know.

Thanks, all great info. Going to do a mock up tomorrow. No doubt I'll be back with more questions following that!

Thanks again.

A 3090 in a P300? I think you will struggle to fit it all in. Also I hope you actually mean a P300A because otherwise no way you will get enough airflow.

And a single 280mm radiator will not cool those components. I would strongly advise a P500A, a 360 in the front and a 280 in the roof.

Hi,

It's the P300 yes. Card fits with room to spare and I have no issues currently with airflow. As I'm only intending to WC the CPU at this stage, is the case still an issue?

Edit: Seems the only difference between the P300 and P300A is the mesh front panel, which also fits the P300, so looks like I'll be swapping out.

Perhaps an incorrect assumption on my part but I thought one of the benifits of WC was cooler temps in tighter spaces. I'm not intending to OC, it was more intended for noise reduction, aesthetics, and to have a project on the go.

Cheers

Jon.

If you get the combo unit, from what i remember (as i use 2 of these in my build) it comes with a standoffs so you can install on a 120mm fan mount. If you're installing it at the rear, it might stick out too much and interfere with your cpu block. This is definitely more dominant in the D5 pump combo as the D5 is a lot taller. The DDC model is a lot slimmer and might suit your build better but i always find DDC's to be noisier. For me anyway as i have quite sensitive hearing, they give me a high pitch buzz which i hate.

alternatively you could mount it on the 280 radiator using a 140 to 120 fan bracket, i don't think OCUK stock these so you would need to source one from elsewhere. From what i can see on the P300, i think this might be the better option as it won't interfere with the cpu block or the the graphics card.

What cpu are you trying to cool? A 280mm is usually more than enough to cool most cpu's especially if you use a 30-40mm thick radiator but a bit more info could help here.

You just gotta keep in mind if you want to cool the gpu at a later date you might struggle.

Generally yes, if you choose the right fans/radiator and pump it can be very very quiet. I've tested certain fans with certain rads that don't work well together for noise but will sound whisper quiet with others. It's best to google for this information and see what works best for the fans you currently have. Also it's ideal to run the pump at the lowest speed possible without hampering your cooling, finding the point in which running the pump speed higher is giving negligible difference in temps will be your sweet spot.

For future-proofing reasons, I would advise against putting a 3090 in a small case. Many have found that they can be very noisy under load as they get very hot. If you are looking for silence, water-cooling the GPU arguably has the biggest benefit. CPU can be cooled quietly pretty easily but GPU not so much. A water-cooled 3090 is also much smaller than an aircooled one, particularly a FE.

Going with a bigger case now and a bigger radiator future-proofs you when you (inevitably) decide to put a block on that 3090.

The CPU is a Ryzen 5 5600X. Thanks I see what you mean now about the res/pump combo, looks like front attached to the rad would be better option. I'll update my original post a bit later with a couple of pics so you can see what I'm working with. Saying that, I also take note of your/others advice for future proofing, so I need to do some thinking :)

Oh yes, the 3090FE is a noisy blighter however undervolting has improved that dramatically without any performance loss I've noticed so far. I hear you on the future proofing, makes sense. To be honest I am a little scared of cracking open that 3090 to WC it, so it might be way in the future before I approach that. :)

It`s a lot easier than you think, I was a bit worried before I did my 3080FE but it`s actually nothing to be worried about. Take a look at these two videos, albeit they`re for the 3080FE but the 3090FE will be very similar, it will give you an idea on what to expect. I`d also recommend 30 minutes of something like the Heaven benchmark to get the thermal pads nice and warm, it makes separating the PCB so much easier.

Thanks. As it happens I did end up watching a couple of vids on fitting the 3090 with an EK block and it does seem that the worst bit would be snipping up all those replacement thermal pads!
 
For the sake of a cpu only loop, i'd probably suggest just getting an AIO until you get a case which is better equipped for a custom loop when you could then incorporate the 3090.

£400+ shopping list for WC bits for a 5600x is insanity, you could sell your 5600x, buy a 5900x and an AIO with money leftover instead of this to put it in perspective....

If you however get a better case for WC loop then you'll be in a much better position to do it.

Thanks. Yes that does rather put it in perspective and it seems I'll not get away from my current case being unsuitable, even as a stopgap. Shame, as it's a neat little case but at least now I can go peruse some other options without restrictions.

OK that's settled then, new case it is. Thanks for the steer and to all contributors above, been a great help.

Cheers

Jon
