CPU Clock Rate

3 GHz

GPU Core Clock Rate

1.556 GHz

GPU Effective Memory Clock Rate

11 GHz


Thermaltake sent me over their new Core P90, along with a box of watercooling gear that I had absolutely no idea what to do with!

Build video: https://youtu.be/8-8ENaKNONs

A couple weeks later and we have Onyx - a complete custom loop with a Ryzen 7 1700 overclocked to 4.0GHz, and a GTX 1080 Ti barely touching 40C°

Custom watercooling has given me a new appreciation for the desktop gaming PC - Onyx has a living aurora to it. It truly feels like the coolant flowing through those waterblocks gives life to the system.

Temps (ambient: 21.5C)

  • Prime 95: CPU - 66.0C / GPU - 29.5C

  • Heaven 4.0: CPU - 41.1C / GPU - 41.4C

Thank you all for checking this out!

It's oddly satisfying to look at these perfectly aligned tubes with these regular bends.

+1 for sure!

skyrise 1 Build 3 points 15 months ago

This is both beautiful and innovative! That MSI X370 GAMING M7 board is a great choise, probably even better that the MSI's Titanium one.

What voltage/settings did you use to achieve 4.0GHz? The temps are awesome! That Thermaltake loop seems to be working like a charm.

Great gonfig!

asone_ submitter 7 Builds 3 points 15 months ago

Thanks! Yeah the X370 Gaming M7 is a very solid board, I wasn't able to achieve 4.0GHz stable on B350 boards but I was here. The R7 1700 is pretty stubborn though and needed 1.46V to achieve that :L

GPU temps are great though!

I think I just came while watching the build-video.

Just one question: Why did you not use the 1800X, Threadripper or an i9? The 1700 seems a little out of place in this build to me, but maybe I'm wrong!

asone_ submitter 7 Builds 1 point 14 months ago

Didn't have any HEDT processors on hand but would have loved to put a Threadripper or i9 chip in there for sure!

asone_ submitter 7 Builds 1 point 14 months ago

Whisper quiet! The Riing Plus RGB fans spin at 1350RPM max but get plenty of air flow at the same time since it's an open case :)

hi_im_snowman 1 point 14 months ago

I usually can't stand white colored tubing/coolant. Just typically looks tacky and cheap, at least imo.

But this is one fantastic exception that truly threw me off and took me by surprise. What an exceptionally well-done build!

A stunning piece of tech if I've ever seen one. Absolutely flawless imo, superb job and the feature is deserved.

Oh and those bends... Crisp, neat and sufficiently complex that they aren't overbearing or too simplistic. Damn pro.

LICKLIGHTER 1 Build 1 point 13 months ago

Does the EKWB FE GTX Ti Waterblock work without having to mod or damage the GPU?

Brainbuster 1 point 12 months ago

accoding to him on Youtube. It does.

Brainbuster 1 point 12 months ago

So I have purchased an EK-FC GeForce GTX FE RGB - Nickel. Product EAN: 3830046995780, and it fit perfectly fine. I am sure the non-RGB version that this builder used also works without any modding needed.


Brainbuster 1 point 12 months ago

@asone_ First of all LOVE the build, but I am curious to know if that is EVGA GTX 1080 Ti is an SC2 ICX version. If so did you have to mod your EK GPU waterblock to fit it? or did it fit on the card without a problem. As of yesterday for some odd reason EK de-listed that GPU Block as being compatible with that specific card. I am trying to watercool mine, but having a hard time finding a block for it.

GPU model I have: EVGA GeForce GTX 1080 Ti SC2 GAMING, 11G-P4-6593-KR

gixxertaz 2 Builds 1 point 12 months ago

Beautiful build. Quick question, Which specific waterblock did you use for your Video card? EKWB doesn't list one for that video card which I also have.


Brainbuster 1 point 12 months ago

So according to the build part list and from the looks of it. He used EK-FC GeForce GTX FE - Nickel (EKWB Product EAN: 3831109831977). I have been searching around for months to see what block I could put on mu EVGA 1080 TI SC2 card as well, and although EKWB says they don't make a specific block for our card... this FE version just might fit. I also asked the same question on the Youtube video linked above, and he said that there shouldn't be a problem. I ordered myself the RGB version of the FE one and should get it delivered in the next 2 days.

P.S: Besure NOT to purchase EK-FC1080 GTX Ti - Nickel {Product EAN: 3831109831915} . It needs to be the FE version. There is a cutout on the plexi for the DVI port that this one doesn't have. I made that mistake and now returning it. Luckily it was from a local store so return is a breeze.

gixxertaz 2 Builds 1 point 12 months ago


When I posted, I missed your question. It's funny, I bought the SC2 specifically for it's features, performance, and it's size. Before I purchased it, I verified that EK carried a waterblock for it. Like you, when I was getting ready to pull the trigger on the block, compatible blocks for the card vanished from EK's website. I almost went a different direction for all of my loop (Non-EK) but since I had so many EK components, I only returned the fittings and got Bitspower. I think they look better anyway. Still waiting for my second video card to be back in stock locally. The last part I need to complete my build. I have it up and running on a single video card and a temporary AIO cooler just to make sure everything was working.

IMPORTANT INFORMATION, There is a waterblock that fits the EVGA 1080TI SC2. I am returning my EK-FE blocks and I purchased these https://www.evga.com/products/product.aspx?pn=400-HC-5599-B1. I believe they are sold exclusively by EVGA with a limit of one per customer so if you need more than one, you will need to think outside the box with purchasing ;) These blocks specifically have a cutout for the SC2 fan header that sticks up.

I was getting ready to modify the EK blocks. I bought a special dremel mill bit and impression clay to do it right but when I saw the Hydro-Copper blocks, I went a different route. They are 34 dollars more than the EK-FE blocks but you don't have to buy a new backplate which just happens to cost around 35 dollars so it is a wash. Plus I like the look of the Hydro-copper waterblocks better than the EK

Thank you for responding.

Jim C.

P.S. I read on another forum that asone/Thermaltake did not need to modify the video card or the block to fit the FE but I can't remember where I read that. I certainly wasn't going to rip the header off of a 900 dollar card. There is one tutorial out there where the guy butchered his card to make one fit. He Pried the DVI connection off, cut the fan header and the LED ports off. I did save that link just because I was horrified. https://imgur.com/r/watercooling/24tzF.

Brainbuster 1 point 12 months ago

I actually got my EK FE RGB block in yesterday and I tried it on, and it fits perfectly.... From the looks of things though it should not be a problem. I picked up a EK nickle plated Nvidia 1080 backplate (not the Ti nor Titan V version) from the local microcenter for like $8, and that works well too with the card/block. I am not sure where this notion of EK's FE blocks doesn't fit the SC2 card came from. Thank you for the link though the community should benefit from your research. Also, I am not sure why that guy destroyed his card to try and make a regular GTX FC block fit on his 1080ti. When he could have just purchased the FE version and be done with it. The acrylic on the FE card I had mentioned earlier has a cutout for that DVI port.

gixxertaz 2 Builds 1 point 12 months ago

Nice, glad to hear. The RGB block did look pretty sweet. I have both of my Hydro Copper blocks and was able to score the second video card which should be here on Monday. Delid and cooling loop build start on Monday evening <Dancing Banana></Dancing>.

It is interesting, I am not sure where the rumor that no blocks fit the SC2 started but I suspect it was from EKWB. I emailed them and asked about blocks that fit and they essentially reiterated that they had no intention of making a block that fit and that I could go with the VGA Universal.

The guy tearing his video card apart was the second best tutorial I have looked at this week. The first was a youtube video of a kid showing how to drill a hole in the case for a fan. He drilled the entire hole with the drill going backwards. https://www.youtube.com/watch?v=M_PwbxNriE0

Hi guys! I also have the same card and i'm a bit confused with this subject! Recently made my custom loop and put the 8700k into it! I also want to put the gpu soon! From the comments i read i'm happy to see that there is actually a full watterblock for this card that fits without modifications! So my answer is: Does this waterblock fits without problems?(mainly i'm worried about the 4pin header) https://www.ekwb.com/shop/ek-fc-geforce-gtx-fe-rgb-nickel

Thanks in andvance! :D

gixxertaz 2 Builds 2 points 9 months ago

Based on what Brainbuster stated below, that EK waterblock will fit with no modifications to the Graphics card. I did not use EK waterblocks. I used EVGA waterblocks that are linked below. For reference, I have not seen more than 40C using the EVGA waterblocks, even during multiple successive graphic benchmark runs.

GiannisLp 4 Builds 1 point 9 months ago

Thank you very much for your answer! It was a pain in the arse thinking of which wb to take for this model! Unfortunately I'm living in Greece and EVGA Europe doesn't have any wb's available, plus they are bit more expensive than Ek's. As soon as i can go with founders ed. Nickel I will choose that to complete my project!

someCleverPun 1 point 12 months ago

Hey im considering buying the P90 for my rig. I want to wall mount behind my desk. But I have a few quick questions.

While the case has a lot of options for cable managing for the internal cables, it seems like any external cabling would look terrible. Since the cabling that would normally come out of the "back" of the computer is actually sticking right out of the side and doesnt have much place to hide.

Do you have any advice for that? How do you manage the power cord, the monitor cables, or any USB devices you have plugged in?

Oh my god this is so beautiful I can’t even express it in words. You are godly and this pc is divine. I love this computer so much I’d marry it. Please take good care of it, like you’d treat you’re son because that is what this pc deserves.

DualNeuron 1 point 8 months ago

Easily one of the most aesthetically pleasing builds I've seen and under $2k, just a work of art. It makes me want to start an open air build.

Rdambrosia 1 point 1 month ago

Great build and awesome hard tubing love the colors.

NobleSavage -4 points 14 months ago

First point... Very nice all round build, tubing in particular is exceptional.

Now for the white elephant in the room... That is not a case, it's just some glass panels suspended in front of a naked build.

What is the point of that?

Surely the point of a case is to 'encase' the build, to protect the components from dust, to reduce sound emissions, to channel airflow etc, those glass panels do absolutely none of those things and are accordingly quite literally useless, they serve absolutely no purpose whatsoever, they are the very definition of style over substance.

I get that you want to show off the build and that's fine, wouldn't that be better achieved without the glass panels which can only reflect light and interfere with the view? (As well as requiring regular cleaning and polishing). I guess from the manufacturers perspective there's no way to make a profit without the useless but reassuringly expensive glass panels.

It (the case) reminds me of modern art, and that is not a good thing, or even 'the emperors clothes', I guess I'm cast in the role of the small boy who sees the truth with perfect clarity and feels compelled to point out to the idiot oohing and aahing grown ups 'But he's not wearing any clothes!'

As mentioned above the build itself is fantastic, it's just the non-case that blows my mind.

supermattdab0ss 1 Build 1 point 14 months ago

That is an open air case that is extremely awesome looking and is very easy to do a custom loop in.
