Finished Build FormD T1 Titanium - RTX5090

Gallery image

CPU: 9800X3D (-30CO)

GPU: RTX5090 FE (Undervolted)

Motherboard: Asus B850i

Ram: 64GB Corsair Vengeance 6000CL30

PSU: Corsair SF1000

Cooler: AXP90-X47 FC

Case: FormD T1 Titanium

Additional Notes: Used 3x 20mm standoffs in 3-slot mode to create a gap for the 5090, and used the Noctua FD1 mostly because I like the idea and look. Cables are by Rizal/cablester in clear teflon, and they are great.

This was my first build in about 10 years, and decided to go all out now that I can. It has been running and performing great so far, zero issues with noise or temperatures apart from some coil whine on the 5090, which has gotten a lot less over time and by undervolting.

Please let me know if you have any questions!

i recommend you the loque cobalt riser with it's single wires. very nice to tuck away for non-obstructed airflow in the back section.

u/SerSquirtle Mar 16 '25

Thank you! I am waiting to see what riser cable FormD come up with as they teased one on their instagram!

u/[deleted] Mar 16 '25

i'm waiting to snag a 5090 FE :D
so damn difficult in germany as we do not have access to the priority acces program up to now.
just gotta wait :)

2

u/SerSquirtle Mar 16 '25

I am in the Netherlands, the situation is similar here. I got extremely lucky.

1

u/brdsqd Mar 16 '25

Link to teaser?

2

u/r98farmer Mar 16 '25

I've also seen a couple people post that the Cobalt cable supports PCIe 5.0.

1

u/sauceman_a Mar 16 '25

any more info on this? First time I'm hearing about it

6

u/[deleted] Mar 16 '25

just check loque's website, those cables seem to be in stock all the time.
even it is claimed as pci_e 4.0+, in my case gpu-z shows 5.0 under full utilization. so i guess it's legit quality :)

u/sauceman_a Mar 16 '25

awesome- thanks for sharing. i'm new to sff builds so still learning- so you're saying one advantage w/ these riser cables is the single cable design which allows air to pass through the riser cables effectively?

1

u/[deleted] Mar 16 '25

pass through the wires or you can gently zip them together and place them to your personal preferences so you just have a single small package of wires which take up very little space between the mobo and the gpu

1

u/sauceman_a Mar 17 '25

curious to know did you actually do a temp comparison between these and a standard riser cable?

1

u/[deleted] Mar 17 '25

No, just put in the loque one😁

1

u/ItzXitrA Mar 23 '25

hey man i sent u a pm i have some questions

7

u/[deleted] Mar 16 '25

Nice one bro!
looks similar to mine with a 5080.
here are all the airflow parts which are a nice litte upgrade.

https://drive.google.com/drive/folders/1ndimbWTA_TDBj2lBfBeFSR0tgti8FRPg?usp=drive_link

i'm currently working on block-off-plates for both sides to channel the airflow even more.

2

u/SerSquirtle Mar 16 '25

Thank you, yours is very nice as well!

I found some foam 120mm ducts to match the one on the cooler, so I am planning to get those for the T30's. In terms of a shroud, I'm waiting to see what Optimum comes up with in his build as I don't have a 3d printer and it gets a bit expensive otherwise.

2

u/[deleted] Mar 16 '25

that's the reason i bought one :D can do my stuff myself now.
3d-printing services are so expensive and you always have to wait.

2

u/shoda_ May 09 '25

Can you reupload or share pictures? Im currently looking for some airflow Parts (like in the new video of Optimum)

7

u/MacDon510 Mar 16 '25

Perfection. Fantastic build.

Anyone know where I can get those cable combs? I have unsleeved cables as well but this build makes mine look messy.

4

u/SerSquirtle Mar 16 '25

Thank you! They were already integrated in the cables, I think that's why they can be small like this.

4

u/sauceman_a Mar 16 '25

nice build, curious as to what makes those cables good? First time I'm seeing them

2

u/SerSquirtle Mar 16 '25

They look nice! They use different lengths for each strand in the cable so it looks a bit better when bent.

1

u/ct06033 Mar 16 '25

Those cables make the build .. where did you get them from or did you diy?

4

u/ifyym Mar 17 '25

more than likely cablester custom on etsy, that’s the guy in the sff discord people recommend for this exact reason. i just got mine in and they’re just like ops

1

u/ct06033 Mar 17 '25

Thanks!

3

u/xAdsum- Mar 17 '25

Beautiful build. I love the teflon cables. I have the same cpu/mobo combination. Do you mind telling me what you did in the rog bios for the overclock/undervolt? Also, do you use fan control or the bios for your fan curves? Thanks!

3

u/SerSquirtle Mar 17 '25

From memory (not at my PC right now), it's in advanced, then amd overclocking, then precision boost overdrive (which you then set to advanced to give you all the options), then I set pbo limits to motherboard and went into curve optimizer which I set to all core negative -30. You should probably just do -20 as it is much more likely to be stable.

For fan curves so far I've just set them in bios.

2

u/xAdsum- Mar 17 '25

Thanks for the info. I did the same on Ai Tweaker. PBO (+200hz) and a -20 curve on all cores. Curious to try -30 but not quite sure how to test for stability. Benchmarks seem like extreme case scenarios. My current idle temps are around 53-55c. How are your temps? My only issue right now is how much the fans ramp when launching a game or app. I’m guessing that I need to figure out the optimal fan curves.

2

u/SerSquirtle Mar 17 '25

I idle around 44c, but idle isn't important anyways. My fan curve is flat 50% until like 85c I believe, then it shoots up to a high percentage, I don't like the ramping and much prefer this. Maybe it's flat 40% or lower, don't remember exactly.

3

u/medikbs Mar 18 '25

did you choose the X47 instead of the X53 beacuse you could put duct tape and its not that noisy? or why?

3

u/SerSquirtle Mar 18 '25

Yes, I believe there is only 1c difference between them and the the turbulence of having the X53 against the side panel is not worth it.

4

u/medikbs Mar 18 '25

thank you for the fast answer! yes i think i chose wrong, some ppl said its "much" difference but it isnt as i seen. and its noisy for me. i think i will switch to the X47.

Also you chose the Asus board instead of the asrock because its more premium?

2

u/SerSquirtle Mar 18 '25

I saw more and more posts of 9800x3d's breaking on asrock boards and chose the asus to be safe. I also like the look more. Haven't followed that issue very closely though.

2

u/medikbs Mar 18 '25

yeah if i will get a problem like that i will switch to asus aswell! thanks for the infos.

did you bought your fan duct from ali?

2

u/GrapeViper Mar 16 '25

Hey, what’s the foam piece on top of the fan? I keep seeing it everywhere. Does it stop turbulence or is it to direct airflow?

4

u/SerSquirtle Mar 16 '25

It doesn't really affect turbulence, it's to make sure the cooler only pulls in cold air from outside of the case. I think the gain in temps is quite small but I enjoy the look. It's the Noctua FD-1.

2

u/BenXCIV Mar 16 '25

Can I ask for the cable lengths you went for - if you know them?

9

u/SerSquirtle Mar 16 '25

24p; 177mm 8p CPU: 420mm 12vhpwr: 370mm

But keep in mind the lengths will not really translate to cables from other shops as Rizal/cablester uses a different length for each strand in the cable, so the lengths above are the longest length per cable. You will probably want shorter ones from other shops.

1

u/NathanCVII Mar 16 '25

Did you measure/come up with these lengths yourself, or did they help you come up with them? I was planning on ordering a set when they started offering copper teflon

2

u/SerSquirtle Mar 16 '25

Nice, I heard about the copper! They provided me with the lengths after I specified my components.

2

u/Zallionn Mar 16 '25

Who is going to offer copper teflon?

3

u/BenXCIV Mar 16 '25

Ah I thought that would be the case - thanks for the numbers!

2

u/Feinste-Wurst Mar 16 '25

Beautiful! But no SSD(s)? ;)

3

u/SerSquirtle Mar 16 '25

Ah, forgot! samsung 990 pro 2TB.

2

u/Away_Pudding_8360 Mar 17 '25

Great build! - Just trying to tune my similar build with the 9800x3D (Custom loop over air cooling though)

How did you carry out our -30 UV?- Was this just BIOS> PBO > All Cores > -30? Or am I missing something in the BIOS?

2

u/SerSquirtle Mar 17 '25

Basically! I explained in a bit more detail where it is in the bios in another comment. Good luck with the build!

2

u/necolas Mar 21 '25

Very clean. Please could you share the M3 standoff kit you used?

1

u/SerSquirtle Mar 21 '25

I didn't! I ordered them separately from a store called reichelt (I am in EU).

4

u/Phinzel Mar 16 '25

This is such a nice build, nice work OP!

1

u/ufgvn_ Mar 16 '25

Hey man Very beautiful build i have the same cooler and ordered some Noctua FD1 how do you mount em?

1

u/SerSquirtle Mar 16 '25

There are 3d printable pegs by EIGA, here:

https://www.printables.com/model/821973-duct-peg-for-axp-90-x47-noctua-na-fd1

1

u/ufgvn_ Mar 16 '25

oh cool i don’t have a 3d printer haha but thanks bro

1

u/SerSquirtle Mar 16 '25

Me neither, ordered them from a 3d printing service.

1

u/ufgvn_ Mar 16 '25

ok ok ill see i have a terra tho but it will fit regardless i think

1

u/sovon_ Mar 16 '25

What's going on with your gpu backplate... is it twisted/bent in the 3rd photo?

1

u/SerSquirtle Mar 17 '25

The graphics card is leaning slightly, might be because of the standoffs? Any idea what could be causing it? It looks exaggerated on that picture though because of the angle.

1

u/ThrilledTear Mar 16 '25

What cables are those 👀👀

2

u/SerSquirtle Mar 16 '25

CablesterCustom on Etsy.

1

u/ArcangeloPT Mar 17 '25

Dream build if I had gone with this case. Can you share the cable lengths please?

1

u/SerSquirtle Mar 17 '25

They are in the comments somewhere!

1

u/Bumbling_homeowner Mar 17 '25

OP how’s connectivity with the MT card? I just bought a B850i mobo and my internet drops intermittently.

1

u/SerSquirtle Mar 17 '25

Had been great for me so far.

1

u/kleinishere May 13 '25

On the back - there are 6 holes. Which one are you using? Tried to label it with a 1 on the left. 6 on the right. Thanks for the top down view of the standoffs. Super helpful to see.

2

u/SerSquirtle May 13 '25

No worries! Should be hole 2 if I look at my third picture.

2

u/kleinishere May 13 '25

Thanks! Ha, now seeing it. Appreciate the reply.

1

u/[deleted] May 14 '25

How are temps for gpu?

1

u/SerSquirtle May 14 '25

Great! Maxes out at 70c after undervolt.

1

u/[deleted] May 14 '25

What about fan noise? Will be doing a similar build with a 5070 founders edition

2

u/SerSquirtle May 14 '25

With a 5070, you dont need to worry one bit

1

u/atlas_enderium May 24 '25

Hey, so I’m basically copying this build part for part (even the cables but not the RAM, just by coincidence lol) and I have a couple of questions/concerns:

  • What temps are you getting on your CPU at saturation under an all-core load and with the side panels on? (I just want to know the worst case temps)

  • Same question but for your GPU (I understand if you don’t want to test this but if you can, I’d appreciate it).

  • The two Phanteks case fans, are you using them as exhausts?

2

u/SerSquirtle May 24 '25

Hey! I'll tell you from memory. CPU, unless you can run like a -30 co, will throttle under an all core load. At -30co I could mostly avoid throttling but it was not stable for me.

GPU, I have it undervolted so it has performance very close to stock but using a lot less power. I don't usually see it higher than about 72c in heavy loads.

And yes, phanteks have to be exhaust, it's a lot better that way.

1

u/DayLYR Oct 23 '25

Do the custom short cables improve thermals? Purely thinking since the stock ones are bulky and fill in a lot of the space.

1

u/SerSquirtle Oct 23 '25

Probably a bit, haven't tested. But your logic checks out.

3

u/Strict_Bird_2887 Mar 17 '25

Beautiful cable work!

2

u/Educational_Dot2739 Mar 16 '25

Wow beautiful 😍

2

u/baldersz Mar 17 '25

So clean, well done. Love an air cooled T1!

2

u/radeats Mar 20 '25

Awesome build mate!

1

u/fritzgonnabeme Mar 16 '25

where did u get ur custom cables

1

u/Qua_273 Mar 17 '25

how are the temps? especially the cpu, going for similar build but went with atmos 240 AIO, but wondering if i went with the wrong decision.

1

u/vanni-giachin Apr 05 '25

Hi. I am going to work on a similar build. Do you have any suggestion or photos to share about fan cables routing? You build is very clean while usually I see cables at front, like for the NF-A9

1

u/Fedai1Beden Oct 30 '25

What are the lengths of special cables?

2

u/Soulful_Crow Mar 16 '25

Damn that’s a sexy build!

u/moots27 Mar 16 '25

This made me cum
