This is my first time building out a small form factor pc, and I'm stoked to get started. The board it got (ASUS Prime B550M-A WiFi II) has WiFi 6, and came with a very bulky wifi antenna. While there's room to set that next to the case (the entertainment center that will house this isn't tall enough to fit both the case and the antenna attached on top of it), I'm curious if anyone has experience with using a different antenna with this board, and if it's preferred, especially from a performance standpoint.

Thoughts?

Curious if anyone else with a Gen 5 GPU in an SFF build has run into this.

I'm running a 9070 XT + ASUS X870-I in a Ghost S1 MkIII and occasionally get a complete black screen while gaming, mostly in The Finals. Windows records LiveKernelEvent 141/117 GPU watchdog timeouts. On the most recent crash I could still hear game audio, but the display was completely gone.

The weird part is I've now experienced it with three different risers:

• Giga-Mega PCIe 5.0
• Louqe Cobalt #1
• Louqe Cobalt #2

Each time the problem starts, I can get multiple crashes fairly close together. If I completely power down and swap/reseat the riser, the system then seems to be perfectly stable again for quite a while. For Context, my last crashed happened about 2 hours into a gaming session.

My current Giga-Mega PCIe 5.0 riser actually negotiates at PCIe 4.0 x16 with the BIOS set to Auto. I'm now testing with the GPU completely stock and explicitly forcing Gen 4 instead of Auto.

I've also ordered a LINKUP AVA5 Gen 5 riser to test. From what i've read on r/sffpc this seems like the most reliable 5.0 riser.

Has anyone else running a Gen 5 GPU through a riser experienced similar intermittent black screens? Particularly interested to hear if forcing Gen 4 instead of Auto fixed it.

Didn't see many using Meshroom + ATX mobo + dual 2-slot GPUs so figured it may be sharing to those interested in similar builds.

Parts:

• Meshroom S V2 (+ extender bracket, did not use their PCIE riser)
• Ryzen 7 9700x (came from my sim rig which got a 9800x3d that came as a bundle with the x870e)
• Noctua NH-L12S Cooler
• Dual MSI Ventus 2x 5060ti (16gb)
  • connected via bifurcation riser
  • top GPU mounted directly to chassis back plate, bottom GPU mounted via stock SSUPD GPU mount
  • not sure if this means much but stress tested at 65-70degC @ 4300 ~ 4700 Gflop/s
• Gigabyte X870E Aorus Elite ATX mobo
• G.Skill Flare X5 Series 16GB x 2
• Lian Li 1000W SFX PSU
• 3 x Noctua A12x15 fans (1 top vent, 2 side intake in extender bracket)

Thermals are healthy/steady, overall decently quiet under load. I've ran some llama3.3/3.1 and qwen2.5 for various light usage and the 5060ti seem to handle well, and having 32gb VRAM seems suitable for my usage (server/private local LLM). Have been a heavy Claude user until now so will take my time learning as I stress test the hardware some more as the build is still fresh.

I'm not an expert on AI/LLM by any means, dumb in general if anything so don't expect me to help with much aside from the build itself. Always open to learning more but be kind.

Thank

Ignore the bad pictures they were taken at 4a.m. 😅, but I finally completed my first SFFPC (my first ever full PC build)

I built this system because I wanted to downgrade/downsize.

Stats:

CPU: 5700x

GPU: Reference Model 6900xt

RAM: G.Skill Trident Z 3200 MHz

SSD: 2tb Kioxia Exceria Pro gen 4 drive

Mobo: Aorus B550i pro ax

PSU: Corsair SF850

CPU cooler: Noctua NH-L9i (37mm)

Fans: 2x Noctua NF-A12X25 PWM chromax.black.swap

All crammed into the FormD T1 v1.1 - 9.5l :)

The build came out super in my opinion and I love the form factor, I was thinking about maybe 3d printing a vertical stand even if it adds volume/worsens thermals a bit.

Also I know the CPU cooler could've been 10mm larger, but my buddy gave it to me for free because he wasn't using it so I thought why not! Thermal performance has been very good. Stress testing using Cine Bench I saw max temps of around 73° deg in both (gpu a bit cooler).

Cable management also came out well, but I was struggling on the GPU side, but I think it's very clean apart from that.

Cost (prices in CHF)(add about 20% for USD):

CPU+Mobo+CPU cooler - 120.- (amazing deal from a buddy)

GPU: 325.- + 12.- shipping

RAM: 105.- incl. shipping

PSU: 164.- (new)

SSD: 175.- (new from scalper 4 months ago)

Fans: 2*27.70.- = 55.40.-

Case + gen4 riser: 100.-

Total: 1056.4 CHF = ~1300 USD

If you guys have any recommendations of what to maybe change, I'm open to suggestions! I was thinking to switch the CPU cooler fans to match, but I think I'm going to met my wallet recoup first 💀

Editing because I realized I didn't glaze the GPU enough, but I'm absolutely in love with the black/silver asthethics!

Jonszo z20 , notice temps cool 4-8 lower when both cases are unlocked. I’m worrying about dust, bottom and sides have dust filter but idk if it’s enough, has anyone tried this?

I finally finished my build with zcool mod custom cables. I have a spare vrm screen from my aio, thought it might still get some good use.

Fractal era 2 case

I do not recommend a 280m aio in this case unless you absolutely need it. Set it up with the fans in a pull configuration for clearnce issues with the top mounting plate (red on here it will fit against the plate if you grind off some stops and part of the rivets) but I used the fabs to offset it downwards and use it as a gaurd to keep cables away. Albeit had to only use 2 screws per fan so the rad could shift diagonally giving just enough clearnce for the top to clip on and case cover to slide over.

😭 excuse the cable management or lack their of.

First SFF build I've done:

Case: Lian Li A4-H2O
CPU: Ryzen 5600XT
Motherboard: Asrock B550m ITX/AC
CPU Cooler: ID-Cooling FX240 Pro
Fans: 2x Thermaltake ToughFan 12
PSU: Corsair SF750
RAM: T-Force Vulcan Z DDR4 32GB 3600mhz
SSD: Kingspec XG 7000 1TB
GPU: Nvidia RTX 3080 Ti Founder's Edition
Wifi Chip Upgrade: Intel AX210

This case was amazing to build in! NGL most PCs now feel like a waste of space to me.

Hey everyone!

I'm currently planning to downsize my PC as much as possible, ideally to around 6 – 7L, without replacing most of my current hardware.

My current build:

• CPU: Ryzen 7 7700X
• Motherboard: ASUS ROG STRIX B850-I Gaming WiFi
• GPU: ASUS Dual GeForce RTX 5070 OC (249 × 126 × 50.6 mm)
• RAM: Corsair Vengeance RGB DDR5 32GB (2×16GB)
• PSU: Cooler Master V850 SFX Gold 850W
• Storage: 512GB NVMe SSD
• CPU cooler: Noctua NH-L9a-AM5 / other low-profile options
• CPU is already undervolted

I've been looking at the VELKA 7 Rev 3, which is around 6.2L.

According to the official specifications, the GPU clearance is around 290 × 43 × 143 mm, so technically my ASUS Dual 5070 is too thick at ~50.6 mm.

However, I've come across several VELKA 7 builds where people have managed to fit GPUs that exceed the official specifications, including builds with a 9070 XT and even an RTX 5080. Some of these involved removing/repositioning GPU support brackets or making minor modifications to the mounting arrangement.

That got me wondering:

Has anyone here tried fitting an ASUS Dual RTX 5070 / a similarly sized (50–51 mm) thick GPU into a VELKA 7 Rev 3?

My GPU is relatively short at only ~249 mm, so I'm wondering whether the extra length clearance could make the thickness issue more manageable.

I'm also curious about:

• Whether the side panel can close with a ~50.6 mm thick GPU
• Whether the GPU actually interferes with the riser/motherboard area
• Whether the GPU support bracket needs to be removed or modified
• Whether the V850 SFX would cause any clearance issues
• Recommended low-profile CPU cooler for the 7700X
• Any other clearance issues I might be overlooking

I'm currently considering the MIDORI 7.5L as the safer option, since it officially supports a thicker GPU and SFX PSU, but if I can make the VELKA 7 work without doing anything too invasive, I'd definitely prefer the 6.2L footprint.

Would really appreciate any real-world experience or advice from people who have built in the VELKA 7 Rev 3.

Thanks!

Guess I’ll have to get used to having no side panel on one side. 🥲

I like the AM5 platform and I've built several PCs for myself and my relatives on in 2024 to 2025, using 9600X specifically. For my next build, however, I want to shake things up a bit.

250K Plus seems like a decent processor which have actually made me not disregard Intel's platforms. But it has much higher TDP than I'm comfortable with in a discreet desktop. Moreover, I want to build the system in the Ridge.

I saw some Ridge builds using 9800X and other AMD chips with a TDP over 65W. But have anyone ever tried to do the same with Intel's latest? Is there anything specific to the platform or the architecture which makes it unreasonable for such a small case? And what are my options for power limiting and curve shaping?

Hey all, putting together a sff, looking for some insight on the MOBO and AIO. Case is an nCase t1 v2.5. Goal is basically 4k gaming in the living room (controller).

Parts:

CPU 9950X3D

RAM: GSKILL Ripjaw S5 (2x32) ddr5 6000mhz cl36

GPU: Asus prime 5080 oc.

Psu: Corsair sf1000.

Ssd: probably just 1 samsung 2tb 990 evo.

I've looked into the available 870 chipsets and the asus has some bad reviews but I'mtaking them with a grain of salt. The gigabyte has better reviews but it seems it's only available in white. More options open up with the 850. I was wanting to hear some insight on anyone else with a 9950 or similar cpu whether or not the gamble with an 870 itx is worth it, whether thats with the asus or the gigabyte, or will an 850 do the job just fine, and if so, which one?

And, alas, I have joined the struggle of trying to find a CM atmos stealth, both 1&2 are backordered/not available yet; do I have any other options for fitment here in the mean time that may be in stock? I have noctua fans @ 25 and 15mm on hand, so mostly just looking for radiator and pump fitment and function.

I am absolutely loving this PC, i know a lot of people will be telling you could have gotten a 5080 for a bit more for the price you paid for the strix 5070ti but honestly, i strictly wanted ROG, hence it was the strix 5070ti or the 5080 astral, and 5080 astral being out of reach, I decided to go with this, i initially planned on taking the 7800X3D but then for a 100 dollar more, i am getting the 9800X3D, so why not, as I plan on emulating PS3 games as well! I did get help from the community too, appreciate everyone!

This is my SFF gaming PC which uses an AMD GPU and CPU. I mainly use it for 1080p gaming and I've been very happy with its performace. RE Requiem at 1080p high settings with FSR 3 upscaling, I got around 75-85fps. With FSR 3 upscaling and frame generation I got around 125-145fps.

The GPU is called the Radeon Pro W7400 8Gb (RX 7400). I believe it's a slightly cut down RX 7600 but tuned for workstation purposes. It might even be the same spec as the one in the steam machine.

I have modded the GPU slightly so I can control its blower style fan speed because at stock ,it is capped to spin at maximum 40% which isn't enough to keep it cool for demanding games. I have set to roughly 80% for gaming.

Its a very low powered PC consuming between 90-130W if I was to guess. It's a shame that this GPU is too difficult to obtain for most people, I was lucky and found it used on eBay. There is meant to be a low profile RX 9060 coming out soon so that could be a better alternative if you wanted an AMD graphics card for SFF builds.

I hope you found this interesting :) As it is all AMD I could use SteamOS but I need to learn more about it and how it works. I will list the parts below.

Ryzen 5 pro 8500GE

Radeon Pro W7400 8Gb

16Gb (8x2) Kingston Fury DDR5

ASrock A620a mini ITX motherboard

Acer Predator GM7 2TB M.2 SSD

Noctua 40mm x 10mm (three case fans, with bracket mod)

Thermalright AXP90-X36 CPU cooler

Noctua 90mm CPU fan (replaced the Thermalright)

Jonsbo NV10 Black case

Enhance ENP-7660b Flex PSU 600W (Nocuta fan mod)

Can anyone who has visited china or lives there, tell me the availability. Is it hard to find? How much is it? I'm planning on traveling there and might aswell grab one while i'm there. Any advice is helpful :)

Finalizing the shroud for the GPU, but it works great even without it. No undervolt needed. Benchmarks and videos coming soon. CPU cooler samples are out to several YT channels. Website and everything else to launch when the first wave of previews come out.

For the CPU side, AM4/AM5 and LGA1700/1851 will be supported. 200W TDP on Intel, 140W PPT on AMD. It will go beyond that, but the fan speed would put it above 45dba.

GPU side, 5060Ti, 5070, 5070Ti and 5080. Sorry, no AMD for now. The PCB is too long for the 4 to 5L target.

Just want to share my open frame build.

Parts I used (the most of them I own since a few years, only GPU, PSU and the case are new):

• XTIA Xproto-N V2 case
• Gigabyte AORUS B760I PRO DDR4 motherboard
• Intel Core i5-14500 with Thermalright AXP90-X53 cooler + Noctua NF-A9x14 HS PWM fan
• ASRock Arc Pro B60 Creator 24GB
• 64 GB DDR4-3200 CL16 Kingston FURY Renegade
• 1 TB Patriot Viper VPN100 NVMe PCIe SSD
• DeepCool PS750G 750W

System temperatures:

Idle - CPU 35°C / GPU 40°C

Load - CPU 68°C / GPU 74°C

I use this machine mainly for video editing+encoding and LLM (llama.cpp SYCL + Jan.AI).

I have a 240mm AIO in a DanCase A4-H2O, and at moderate to high speed the fans create a resonance, called beating, because of their similar, but not identical blade frequencies. I've been looking at getting some new fans to improve cooling and noise, but wondering if people have used 2 different fan models with different blade frequencies?

An example would be the Phanteks T30 (7 blades) with a Noctua A12x25 G2 (9 blades), where at lets say 1800 rpm, they would have primary blade modes of 210 Hz, and 270 Hz, creating a 60 Hz beat frequency (high enough to not be noticeable).

Noctua does have a set of fans with offset rpm to avoid beating, but even with a 100 rpm offset, the modes are only separated by 15 Hz, and there is additional performance loss from not having equal fan performance.

I've decided on getting the M2 case by ncase. What GPU should i get that will fit comfortably? I currently have a 3060, but i'd like to upgrade soon. I'm just a casual gamer and mainly play story and casual games (First Light, Hitman, pga2k, Madden, GTA, etc.) But id like it to be able to run GTA 6 smoothly when it finally comes on out pc (that's important to me lol).

Any recommendations would help a lot

So, I've looked into some sff GPUs and the sff tax is kinda scary, but it seems that changing the cooler/heatsink can be a good alternative.

So where can I find any resources of this (GOOD tutorials, lists of compatible heatsinks, etc). I can see that the PCB is single fan sized but I have a 250mm something dual fan heatsink on it.
