Description

Usage

Going to be using this machine for 3D modelling/ texturing and rendering with some gaming too. Needs to be compact and easily transportable as well. RTX 2070 is used with Substance Painter for I-Ray rendering- the 8GB VRAM is very useful here- renders are very quick at high sample settings. I believe some of the advanced RTX features are helpful in texture baking in Substance Designer (or will be in future) but haven't tested that yet. 32GB RAM is just a buffer in case 3D stuff gets crazy with photoscans or just working at the same time as rendering.

Performance and Temps

I'm using the stock cooler and the beta bios for the B450I Gaming Plus with RAM XMP profiles loaded to run at advertised speeds. Before cable mangement and a trip into Ryzen Master "Creator Mode" it ran very hot at stock settings (up to 95°C at 100%). I lowered the voltage down to about 1.2v and limited speeds to 3900MHz which reduced temps to 77°C in the built in stress test whilst not affecting render times very much. I've also added a 140mm ARCTIC P14 PWM fan to the front roof slot which has reduced temps by about 4-5°C whilst all cores are rendering.

Games

Subnautica, Wolfenstein II, Hitman 2 and Witcher III run perfectly and Quake II RTX hits 60fps with Global Illumination enabled. Running these at 1080p so its not really suprising. Steam VR test scores "Very High" and has no drop below 90 fps.

Build

Case was a bit difficult to work in, but I've only ever built in an ATX so maybe thats just me. Installed the PSU first as instructed but couldn't get the motherboard in so had to redo that stage. The RTX 2070 managed to squeeze in behind the PSU cables. Decided to remove the internal drive bay so the CPU had a bit more room to breath.

Upgrades

Maybe looking into getting a more suitable 3rd party cooler in future. The stock isn't really working for me at higher speeds (4GHz +) given the space in the case, but having so many threads available for rendering means even with a limit on clock speeds its still REALLY fast. I've added a case fan since completing the first build and that has reduced temps a few degrees.

Part Reviews

CPU

Ridiculously fast for the price in multi-threaded applications, if you do any sort of 3D rendering in Maya/ Blender etc this will do the job.

Motherboard

An ITX board that supports the Ryzen 3900X with the beta bios for a fraction of the cost of a new x570 mobo. Would be nice if it supported 64GB but I think I'll struggle to max out 32 in normal usage for rendering.

Storage

Fast, small, cheap- does what it needs to which is boot up and load programs quickly. No complaints.

Video Card

Large but still fits in a Core 500 case. Runs everything at 1080p perfectly. Quake II RTX is worth trying it out for free to enjoy the Raytracing effects as they make a massive difference to the atmosphere.

Case

A bit tricky to work with but worth the effort. Manages to fit a Ryzen 3900X, RTX 2070 and ATX PSU in. Rear fan is very quiet. The magneticdust filters are a nice feature and there is plenty of space for air circulation with the drive bay removed.

Power Supply

Enough to power a 3900X and a RTX2070.

Did you have any trouble mounting the stock cooler? I was looking into making a similar build, and when researching this motherboard I saw people complaining about the amd stock cooler running into interference with the heatsink on this motherboard.

Hi I'm afraid I can't really answer this- the mobo needed the bios updated with another CPU for the 3900 to be recognized first so I had it installed by the store at the same time (20 mins to do both these things so it might not be that bad?). If you're worried about the mount then I recommend getting a 3rd party cooler as it really does like to get toasty with this one, at least with the amount of airflow it gets in my case .

Awesome build!! How’s modeling going? I’ll be doing a 3900x build for 3D design (mostly CATIA/Solidworks) and some gaming so I’m eager to know!

Cheers, yet to test out the latest version of Zbrush but I know its perfectly good for modelling in Maya!

Nice build man! Just to let you know in the Fractal Design review there is an error it says "Ryzen 2900x" when you probably mean Ryzen 3900x, just to let you know. Otherwise its a fantastic build and was thinking of building a pc with similar specs soon, but with a 2080 Ti instead :D

Good spot, yeah I'm pretty happy with it so far- just make sure to get a decent cooler as well!

Are you planning to upgrade the cooler? I am planning a similar build and curious about other 3900x users

Not at the moment, I've just added another case fan to help with airflow.

How well does the AMD cooler work? Is it worth upgrading?

Beast Machine -- Looks great! I am also looking to build a 3D modelling/Render Machine with Ryzen v similar to this as love the small form factor. Couple of questions :D Have you done any intensive CPU rendering if so how does it preform? And have you done any GPU intensive render/raytracing that you could feedback on.

Nice build - think an aftermarket CPU cooler will most likely benefit it. 1 uptick from me ;)
