PCPARTPICKER 3950X

Scouring The Parts

Where to even begin with this one. Downsizing from a sub 6 liter case to this sub 4 liter case while also simultaneously upgrading the CPU from a Ryzen 5 3600 to a Ryzen 9 3950X is asking for some hot hot trouble. Thankfully, most parts weren’t too difficult to find.

CPU

3950X, a 16 core beast, 105W base TDW with about 144W at max cylinders. This is a beast of a CPU for the price, though I have to admit that the price of this single component is the price of some other people’s completed build.

CPU Cooler

I am using a Jonsbo HP-400 heatsink coupled with a Cooler Master 9215 RGB fan from their MasterAir G200P CPU cooler. This is to ensure I stay at the 37mm CPU cooler height. If I had used a Noctua L9A heatsink, it would sit at 38mm and the closeness of the fan to the side panel might create turbulence.

The two case exhaust fans definitely help in cooling the hot beast of a CPU. I am setting the case exhaust fans at 60% speed as the max speed to help with noise. This is helping my GPU cool itself too so the GPU fan curve can be lower too.

Motherboard

After looking at some of the other mini ITX boards, this is probably my favorite due to the BIOS. Everything is easy to manage and work with. I am very satisfied.

Memory

I initially went with some G.Skill Trident Z Neo clocked at 3600 with a Cl16. However, the 44mm RAM height listed seems to be only up to the LED part. It wouldn’t fit in this case with a max height of 45mm. If this ram, including the fins was like 3mm smaller, I would be going with those.
Due to this, I ended up going with these Corsair LPX ones, XMP at 3200 with a Cl16 (2x32gb) for 64gb total of RAM. I manage to overclock these to 3600 with a Cl18.

Storage

I am using a Corsair MP600 2TB drive. Managed to buy this piece for $280 so I am more than satisfied for what I got for the price.

Video Card

This is, currently, the fastest GPU one can get in the ITX (Sub 180mm length) format. I believe Gigabyte will be announcing and releasing a 2070 Super sometime in the future so I will upgrade to that when it does come out.

Case

This is probably the smallest case anyone can get that will fit a mid-tier/high end GPU. At 3.7L, 225mm x 172mm x 97mm (HxLxW), you realistically can’t get any smaller than this. There are some photo comparisons with this case and a PS4 controller.

Power Supply

Probably the best Flex ATX one can get. Platinum rated for 650W and has a relatively quiet fan curve compared to other Flex ATX units.

The custom version I’ve been waiting for seems to be delayed so I will use the regular model until the custom version arrives in March. The custom version has thinner, easier to manage wires, all black enclosure, and quieter fan curve.

Use Case

This is primarily going to be used for gaming. I'll get some gaming benchmarks when all the parts are in order as well. There will be some video editing and other uses potentially, but for now games.

Peripherals

I'm using a Dell S2719DC monitor. This is 1440p with a 75Hz refresh rate, I probably won't update this monitor for some time, I want a good USB C capable monitor to work alongside my Macbook. I have a full set of Razor keyboard, mouse, and mouse pad; all RGB naturally.

I also got some custom WIFI antennas so the little stubs sticking out are the wifi antenna! Same speed but at a quarter of the size.

Benchmarks and Thermals I'm in the process of running some benchmarks and thermals to see how this little guy performs and how the case fans affect temperatures. Once I'm done, graphs will be uploaded!

Smallest hot box you’ll see 😂

Oh man, that is an insane amount of power in something so tiny! It reminds me of a friend of mine that put a 572 big block into a chevy vega. It overheated a lot and definitely could not use the motor to its full potential but boy was it a lot of fun. This build is pretty awesome!

Thank you! :3

It absolutely is. Probably the most power CPU and GPU wise that anyone can squeeze into such a small case.

That is awesome! Where does the PSU sit in this case? I couldn't see in the pictures.

The flex ATX PSU sits right below the motherboard

Yea i have been seeing this popping up on aliepxress for a while and i have some friends who are interested in this for a build. Its not even particularly expensive (61 dollars) but you do need the riser cable which isn't cheap at 32 bucks (though id personally just buy a cheap ebay special for 7 bucks. the power supply is pretty expensive though. the cheapest being a silverstone 350 watt for 90 bucks. that pretty much limits you to a 1660 super or if you want to go cheaper for gaming like an rx 480/470).
nice job with the build.

I'm curious to why you chose your cpu and case for gaming? Your not limited for space in your room there. Why didn't you go for a more roomy ITX case or mATX, drop down to a ryzen 9 3900x, use that extra money for a much better graphics card and premium cooling? My VM workstation and analytics computer runs a 3950x and I've noticed less than 10% increase over my partners 3900x. For gaming you would see no performance boost for price increase. 64gb ram for gaming? You'll see zero increase in FPS, only will notice when you have 10 or 20 applications open at once.

Nice build, very compact. But 95c on your CPU is to high. You'll be thermal throttling the entire system during gaming, and the fan isn't sufficient for heavy graphical workloads.

he knew the consequences of going with a smol PC. Building a smol PC will come with its regrets but at the same time you can’t deny the rig is different among other builds on this site.

I figure I would thermal throttle this build, but temps in some preliminary testing isn't so bad. From idle, a single cinebench run jumps it to 83 C with PBO enabled. Once I get some gaming benchmarks and temps in, I'll upload a full graph. I know for sure I am not utilizing the full extent of it, but it is nice to be able to say I have a 16 core beast in a 4 liter package haha.

Not saying it isn't. It's a really nice build. I'm just curious as to why he picked the parts for it. Workstation components, HTPC case, gaming machine. It's just not what I view is ideal compatibility and I just wanted to know if he picked his parts specifically or just got the most expensive parts possible

Does the memory come with Samsung b-dies ? Can you check for me ?

Hello! The memory does not come with Samsung B-Dies. It comes with some sort of Hynix. Thaiphoon is unable to get the exact model, prob due to how low volume these 32GBx2 ones are.

Added some thermals to the final photo. Cinebench Once = peak temperature in the very first cinebench run. Cinebench 3x = running cinebench 3x consecutively to see temperatures Heavens benchmark was run for 15 minutes and the peak temperature was selected as the value FFXV Benchmark was run once and the peak temperature was selected as the value.

GPU Peak Temperature during gaming was about 62 C.

Insane and incredible build simultaneously - presume you've a direct line to your local firefighters ;)
