I posted before having a 5800x3d wanting to upgrade to 9800x3d for temps, and all I can say it's worthit...

Specs:

- SKTC A07 4.3L case

- Ryzen 7 9800x3d

- RTX 5070 colorful mini

- ROG STRIX B650i-e ITX Motherboard

- Thermalright AXP90-36

- 32GB DDR5 RAM 6000mghz

- 2tb SSD

- FlexATX Power Supply SilverStone FX600z Platinum

-Mx-7 Arctic

Total: 1600 dollars

Temps went down by alot, in Valo 5800x3d average temps is 80 degree and peak of 88, 9800x3d has an average of 67 and peak of 76..., honestly speechless.

Idle it is in low 50s, I am using pbo-35 eco mode

Now cause this is the absolute best temps wise I feel empty, nothing more to upgrade, I feel free but empty🫤

Hi all, I'm working on a modded Meshroom D to fit triple 280mm radiators inside with all mesh panels. Does anyone have pointers on what fan orientation would work best for something like this? All intake?

I was planning to move to the Lian Li DAN A4-H2O as part of my RTX 5080 upgrade. Naturally, I originally intended to get a card that would fit within the case’s stock dimensions, such as the ASUS Prime. Unfortunately, due to the current GPU market situation, I couldn’t find one available in my area.
I eventually managed to get a great deal on an MSI RTX 5080 Gaming Trio OC instead, which ended up costing me less than an ASUS Prime would have if one had been available.
I’m aware that the Gaming Trio OC exceeds the DAN A4-H2O’s official GPU length limit, and I know there’s a 3D-printed front panel extension that can accommodate longer cards.
However, my main concern isn’t the overall length, but rather the slot/opening in the inner front frame of the case. Does anyone know its exact dimensions? More specifically, would the Gaming Trio OC fit through that opening without touching or interfering with the metal frame?
Has anyone attempted this particular combination, or tried fitting a similarly sized GPU? Any measurements, pictures, or firsthand experience would be greatly appreciated.

Hey r/sffpc,

Finally finished dialing in my sub-5L build. The LZMOD A24 v5 is an incredible chassis, but anyone who has built inside dense Flex-ATX sandwich layouts knows that stock PSU cables and high-RPM miniature fans can make both cable routing and acoustics a nightmare.

I took this build a step further: replaced the stock PSU spaghetti with a custom handmade harness, swapped key coolers to Noctua, and repurposed the stock parts to target internal hotspots.

The Specs

Case: LZMOD A24 v5 (~5L)

CPU: AMD Ryzen 5 7500F

Cooler: Jonsbo 37mm low-profile heatsink

GPU: Gigabyte GeForce RTX 5060 Low Profile

PSU: Metalfish 600W Modular Flex-ATX

Cables: Fully custom handmade harness (16 AWG / 18 AWG silicone wires + Molex Mini-Fit Jr.)

Cooling & Fan Optimization

Stock 40mm Flex-ATX fans and budget slim fans can get whiny fast, so I overhauled the entire thermal layout:

PSU Fan Swap: Replaced the stock Metalfish 40mm screaming fan with a Noctua NF-A4x10 FLX / PWM. The acoustic difference at idle and moderate load is night and day.

CPU Fan Swap: Replaced the original stock Jonsbo fan on the 37mm heatsink with a Noctua NF-A9x14 PWM for much quieter static pressure through the fins.

Repurposed Auxiliary Airflow: Instead of tossing the original slim Jonsbo fan into a parts bin, I mounted it as a dedicated auxiliary spot fan directed right at the motherboard VRM, RAM sticks, and the M.2 NVMe heatsink. In tight cases with no natural convective airflow, this dropped component soak temps noticeably.

Custom Cable Harness

Cables: Built from scratch using ultra-flexible 16 AWG (12V high-current lines) and 18 AWG silicone stranded wires.

Fitment: Every lead was measured and crimped down to millimeter tolerance. Zero excess loops, which cleared an unobstructed airflow path directly from the fans across the spine.

Thermals & Sound

The fan mods combined with unchoked airflow make this easily the quietest sub-5L build I’ve run. The 7500F stays cool under sustained gaming loads, the VRM/M.2 area no longer heat-soaks, and the PSU runs virtually silent instead of whining like a server rack.

Happy to answer any questions about the 40mm PSU fan swap, pinout, or clearances inside the LZMOD!

After what feels like FOREVER, I’ve finally built my dream SFF gaming PC! 😭❤️
Couldn’t be happier with how this little beast turned out. 🖤🔥

The Specs:
🧩 Motherboard: Gigabyte A520I AC (No other board was available 😹)
🚀 CPU: Ryzen 7 5800X3D
🎮 GPU: ASRock Steel Legend RX 9070 XT 16GB
⚡ RAM: 32GB DDR4 3200MHz
🔌 PSU: Corsair SF850
❄️** CPU Coole*r: Thermalright AXP90-X47 (It’s struggling to keep the 5800X3D cool, so an AXP120-X67 is already on the way*! 😅)

Building this in the SGPC K49BL has been such a fun journey. Getting this much performance into such a tiny case is honestly insane. 🤯

Also, special shoutout to Official SGPC site. Got this case for only $76+$20 shipping with all the accessories (even though I chose the case without wooden handle ❤️)

Now I just need to sit back, fire up some games, and ENJOY THE BEAST! 🎮🔥

(used AI to refine the post)

Through a fortunate-ish set of circumstances I've been able to get my hands on 2 32GB sticks of DDR5 SO-DIMM RAM as well as a 1TB SSD (Long story short, I got a 2nd-hand mini pc for stupid cheap only to discover it had better specs than advertised. But the motherboard died not long after getting it and I had to salvage the still working parts)

Rather than selling the ram/ssd I could salvage I'd ideally like to make a sff build for 1080p/60fps gaming. I believe I've settled on the Jonsbo T9 for the case to house it all in. But after doing some research when it comes to the motherboard I think I need some advice before I start making a plan for the rest of the build.

Should I go for the Minisforum BD775i to save some money (As on Amazon right now its going for what looks like a very reasonable £265/$355) which would also let me make use of the SO-DIMM RAM I currently have. But knowing I won't be able to upgrade the cpu later on.

Or should I look for a mobo/cpu combo which will almost certainly cost a bit more, and sell/replace the RAM I have (Or see if a ram adapter will work) but with the benefit of being able to upgrade it later on if needed.

As I'm typing this out I'm leaning more and more towards the Minisforum board just for the simplicity of it and based on the parts I have already. But as I'm very much a beginner when it comes to PC building I wanted to get a second opinion on if the lack of upgrade possibilities will come back to bite me or if theres any other important factor that I never even thought to consider.

Any help would be greatly appreciated!

Hi guys, i have a mini-ITX build and i need a cooler for my new i5-11400F (im currently stuck with an intel stock cooler), will the Thermalright AXP-90 X47 fit my mobo? I need a good low profile CPU Cooler that doesnt take much space in width, since the intel stock cooler already barely fits. My case is the MCM Mars Gaming.

Hey all. I'm in the process of planning a small PC build for my basement HTPC setup. I've got most of the parts picked out, but I'm struggling to find an appropriate case. Here's what I'm planning to go with:

• CPU: AMD Ryzen 7 9700X
• Cooler: Noctua NH-L12S
• GPU: RTX 4060, which I'll be sourcing used at some point. I'm leaning towards the ASUS Dual OC GeForce RTX 4060 8 GB.
• PSU: Corsair SF750
• RAM: DDR5-6000, aiming for the lowest-profile kit possible. Hoping to snag something on sale for Black Friday.

A bit more context on the setup: I currently run F1 Multiviewer across seven displays, consisting of three 1080p TVs and four ceiling-mounted 32" 1440p monitors. For this reason, I've focused primarily on single-thread performance while keeping TDP as low as reasonably possible.

The RTX 4060 will drive four of my displays, so I need an ITX motherboard that can support three additional displays through the CPU's integrated graphics. From what I've found, the ASUS ROG STRIX X870-I GAMING WIFI Mini-ITX seems to be the main option, with one HDMI output and two USB-C ports supporting DisplayPort. That said, I'm reading some pretty mixed reviews about this board, so if there are other options meeting this requirement, I'm open to suggestions.

I'm currently using an Intel Phantom Canyon NUC (Enthusiast model), which I'm planning to move into my living room setup, where it won't need nearly as much performance. This new build should be a nice upgrade for this setup.

Ultimately, I'm looking for the smallest case possible that can accommodate these components without compromising performance or cooling, while still fitting on a shelf in my media console or AV rack.

I'd originally looked at the Fractal Ridge, but I've come across quite a few comments about cooling being compromised when it's used horizontally. The SilverStone Milo 12 was another recommendation, but it seems a bit larger than I'd like, so I'm hoping to find something that strikes a better balance between size and cooling.

What cases would you recommend looking into? Ultimately, if I need to go a bit larger to make this work, I can figure it out, but just looking for a starting point. The B4-mATX also came across my searches this morning, so I'm looking into that as an option as well, but it also seems potentially overkill for what I need.

Cheers!

I like to invert the case position switching the feets when i get sick of it
Btw, this airflow works perfectly?
Based on the first photo:

I recently bought a small N100 PC to use as a home server, and I'm looking for a silent PSU.

Honestly, I'm a bit overwhelmed. I really care about my hardware, so I want to avoid any generic, low-quality units with high ripple that could accelerate the degradation of the motherboard capacitors.

I've spent a lot of time searching for a reliable Pico PSU and concluded that the HDPlex 250W was the best option. Yes, it costs more than the PC itself, but it seemed like the most solid choice of them all. However, I just found out that its ripple levels might be questionable too...

What should I do? Which fanless PSU is actually the best in the low-power segment?

I'm curious how much difference case volume actually makes for thermals and noise in an SFF gaming PC.

On paper, a 10L case looks great for portability, but a slightly larger 12–15L case might offer more room for GPU airflow, better CPU cooling options, and less aggressive fan speeds under load.

For those who've built in both sizes, did moving to a larger case noticeably improve temperatures and acoustics, or did undervolting and fan tuning make a bigger difference?

If you were building again, would you prioritize the smallest possible footprint or give up a few liters for a quieter system?

My set up is in my small California basement which can result in a hot, uncomfortable space after extended computer usage. I had been thinking of ways to make the room more comfortable in both sound and temperature, and came up with system in the photos that I just finished. The room is adjacent to my mechanical room/unconditioned crawlspace, which is always much cooler in part from the heat pump water heater and it being a crawlspace…

I am dumping the heat into an Alphacool Supernova 1260mm ghetto mounted with some painted angled aluminum from Home Depot and 2x4s I had laying around. A nano tube res at the high point makes for easy fill and draining from the rad port. I actually fill it from the bottom was port by creating a vacuum at the reservoir port with a cheap harbor freight brake line hand pump, opening the valve on the rad and it sucks up the fluid from a bottle sitting on the ground.

Specs:

7950x3D with Alphacool Core 1 LT block

Asus Strix 4090 with Heatkiller V Pro block (slight under volt precaution for SF750, this is the only block to my knowledge that fits horizontally in the ncase m2 for the 4090)

64gb T Force 6000mhz CL 36

3 TB total nvme storage

SF750 PSU

Old EK TOP D5 pump and Nano Res from my first loop on my 1080ti setup (RIP)

Alphacool Apex Grip fittings And Koolance QDC through a stainless outlet faceplate I drilled through with a step bit, all EPDM tubing.

Loop water temps are ~20 C at idle/25 C under load & extended benchmarking. Max Cpu temp has been 51 C and the card hovers in the 40 C range. With the D5 at 50% the entire thing is completely silent. Definitely a cool project and a success for what I wanted to do, though not as “aesthetic“ as the MORA crowd on here. I think it’s technically more SFF than most external rad builds since you can’t see it.

My case is a FormD T1, and I've got two SSDs. One is on the front of the motherboard under a good radiator, but it's a weaker PCIe Gen 3 drive without any controller components that heat up significantly. The second one is a newer Gen 4 1TB drive on the back of the motherboard, so it sits right between a hot GPU and a hot motherboard, and it's running completely bare—no radiator, not even a thermal pad.

On heavy loads, my GPU heats up to around 65–70°C, the CPU is at 50–55°C, the motherboard can reach 70°C (hwinfo shows that), and the second SSD's hotspot on the back is always 90–100°C (though I don't know if that's real or not, because its overall temperature maxes out at 50–60°C, and I don't see any throttling effect).

I want to install liquid cooling on my CPU. Should i do that? I want to switch from 14400F to 14600K and my low profile fan from 14400 won't cope with 14600K's TDP

Finally swapped the case and built one of my dream setups! It was quite a work to reassemble all those grills - last pic is all the bits you should unscrew to fully detach them.
Overall, I’m satisfied with this look. Quite a refreshment during the mid-term🤣

To those who have experienced travelling abroad with their ITX, what bag did you specifically used? I was planning to get one for my self but I have no idea what is safe or not safe to use, would prefer wheeled luggage to reduce strain on myself, but got the capacity to protect my pc. TYIA

I'm looking for recommendations for a complete sleeper(ish) SFF gaming PC parts list.

My goal is to build a PC that looks like an ordinary, unassuming little box for someone to look at and assume it's a basic office computer, only for it to secretly be extremely powerful.

My priorities:

• Extremely quiet operation, including while gaming.

• 1440p 240hz gaming in a mix of competitive shooters, rhythm games, sandbox games, and AAA titles.

• A small, understated enclosure without flashy gaming aesthetics or RGB.

• Good component reliability and a well-balanced build.

• At least 1TB of storage.

My budget is $2k-3k USD, already have peripherals. I'm open to mini-ITX or other compact configurations and would rather have a slightly larger box that runs quietly than an extremely tiny PC that gets loud.

I'm not looking for a custom-built enclosure or someone to assemble the PC. I want recommendations for the case and a complete, compatible parts list that I can purchase and build myself. I live in the US and would probably be ordering the parts online.

Edit: I want to go with the formd t1 case. If I want to focus on noise levels the most, what would be the best way to go?

Current Part List:

Ncase m2 or m3 / 9800X3D / 9070 XT / B650E-I / 32GB / 2TB / SF850 / need recommendations for air cooler / 2x Noctua NF-A12x25 PWM

Would these parts work and/or are there better options that I don't know of?

I would like to prioritize good value for the cost without spending too much on diminishing returns.

My second FF10 black arrived! Now I can start working on my two-tone FF10 project.

After looking through various Fractal Design Ridge mods on Reddit, one thing that really caught my attention was the idea of adding a front fan.

Given the size of my dGPU (a SAPPHIRE NITRO+ Radeon RX 9070 OC 16GB), I was realistically looking at fitting just one 60 mm front fan.

That led me to two of what seem to be the more popular ready-made 3D-printable designs (or at least the ones I kept coming across):

The thinner design**:**
https://www.printables.com/model/928672-front-60-mm-fan-mount-for-fractal-ridge-standoff-f

The thicker design**:**
https://www.printables.com/model/713482-fractal-ridge-pc-case-front-fan-mount-40mm-and-60m/files

I tested both, and I have a few observations about each.

The thinner design

The biggest issue I found was the upper-right fan mounting hole (looking at the case from the front).

There's simply not enough material around that area. Depending on the print, it might already come out a little rough, and after driving the included screw in once or twice, the material around the hole can get pretty chewed up.

The thicker design

This one felt noticeably more robust overall, but it had a different problem.

There's too much material around the upper mounting points where the bracket attaches to the case. With my SAPPHIRE NITRO+ installed, there was simply no way it would fit between the GPU and the case without modification.

So, what did I end up doing?

Of the two, I decided to go with the second design, mainly because it felt much sturdier.

I grabbed my Dremel and started carefully removing the excess material around the upper mounting points, finishing everything off with some fine-grit sandpaper.

By taking off a little material at a time, I was able to fine-tune the fit and get the clearance just right.

What about heat-set inserts?

Interestingly enough, I actually wanted to avoid using them if possible, so I decided to try fitting everything without them first.

That meant making a few small adjustments here and there — slightly enlarging a hole to accommodate a screw head, smoothing out some edges, and generally tweaking the fit until everything sat properly.

And the result? Well, you can see it in the photos. :)

Long story short, I'm really happy with how it turned out. It's one of those little DIY projects that's just incredibly satisfying when everything finally fits together.

Components used

• Fan: Noctua NF-A6x25 PWM
• Fan grill: Noctua NA-FG1-6 Sx2

As a side note, I also connected the two additional side fans next to the dGPU to a single motherboard fan header using the Noctua NA-YC1 4-pin PWM Y-splitter included with the NF-A6x25 PWM.

And finally, special thanks to Igor, who 3D-printed the prototypes for me to experiment with! :)

Sometimes the fun is in making things fit where they weren't originally meant to (hehe).

-------------------------

One more thing worth mentioning: the modified bracket can be installed without removing the GPU or any other components from the case!
