SFF Ncase M1 // Ryzen 5 2600X + GTX 1080Ti FE

by twoscomplement


My first small form factor (SFF) build.

12/2018 Update

GPU Cooler - The stock GTX 1080Ti cooler just wasn't cutting it in the small case. Under boost, the GPU was quickly being thermal throttled. Adjusting the fan curve up works, but is just too loud. Like many others, I opted to install an Accelero Xtreme III. Best results were achieved with CPU fans running as intake from the rear and bottom fans exhausting out the bottom. The 1080Ti can now sustain full boost and at reasonable volumes.

Black screen crashes - While stress testing and benchmark-ing, the PC was crashing to black often. If your run into this, disable or uninstall AISuite. Crashing happens when multiple monitoring applications polling for measurements at the same time. Once AISuite was removed, the problem went away.

Fan Control - Argus Monitor is a great replacement for Asus FanXpert. Comes with a host of monitoring options and fan control tools. Most importantly, it doesn't crash when used with HWMonitor or MSI Afterburner.


Save Desk Space - Having side-by-side gaming PCs is important to us, but our current living space doesn't allow for too large a desk, The old mini-ATX was just taking too much room whether it was placed on or beneath the desk.

Travel to LANs - Wanted to have something that could travel around with me easily to local or regional events.


Corsair SF600 80+ Platinum Certified - Note the parts list includes the 'Gold Certified' version of the PSU I originally purchased and returned. Before starting the build, the Platinum version was introduced. For a small premium you get individually sleeved cables that fit very well inside the M1. There are also some reports on the SFF forums that the platinum has an updated fan curve for more silent operation.

RAM for Ryzen - Ended up ordering the G.Skill Trident Z RGB RAM twice. First ordered the GTZR Intel optimized SKU before noticing and then reordering the GTZRX Ryzen optimized version. It probably makes little difference outside synthetic workloads and RAM overclocking.

2 NVMe SSDs - One of these drives migrated from a previous build. The original intent was to install a new NVMe SSD but decided to include both. This reduced the extra cabling needed to connect additional SSDs at the front of the case. I am currently running both drives in software controlled RAID0. One of the drives splits PCI-e lanes with the GPU, but this doesn't seem to impact gaming performance as BUS utilization never saturates.

Potential Next Steps

Accelero Xtreme III - The current configuration of the case with the GTX 1080Ti FE can't sustain OOB boost clocks under synthetic load and default fan curve. Adjust the blower fan curve can get it there, but causes the system to run very loud. This hasn't been too much of an issue in practice, but I may consider replacing the stock cooler with the Accelero heat sink and rely on the Noctua 120mms to exhaust out the bottom of the case.

Love the build man. Btw how's the 2600 I was thinking of getting due to the price but I was going for the 2700x

Looks nice, I'm a fan of SFF builds. I'm planning an itx build now with the Ryzen 2600 for low power and thermal. It has more power than anyone needs, there is no reason for 24 threads unless maybe you want to run a bunch of VMs. Maybe try a hybrid GPU with the radiator blowing out the top.

If you're going for the GPU heatsink, pushing cool air on the fins is better than pulling heat away, since cool air directly hitting the fins and the VRM is better than trying to extract heat with negative pressure (also sucks in dust from other parts of the case)

Trust this. I can confirm.

In my testing, exhaust out the bottom has been better. My guess is there isn't enough pressure to push the air up and out of the case. Intake might work if the stock case feet are raised some.

Toit like a toiger! Looks sweet man! What are the temps looking like tho with that beefy 1080ti in there?

rocketracer111 1 Build 2 points 4 months ago

Clean! For the accelero you can check out optimum techs build at YouTube and here on pcpp but without the accelere.

nice build tho +1

uberlittle44 1 Build 1 point 4 months ago

Great looking build! Have you overclocked your CPU?

twoscomplement submitter 1 Build 1 point 2 months ago

Currently relying on Precision Boost Overdrive and XFR, which gets 4.025Ghz.

Nice build! I'm about to upgrade from AM3 myself, and I'm wondering where the difference in Ryzen optimized RAM is notated when purchasing.

My understanding is that it mostly has to do with motherboard compatibility. Memory performance does have quite a bit of effect on Ryzen, so it's worth making sure you get the speed and timings you're paying for.
