"RED Flow" - 9900K ITX Build

by itx99k


This build is targeted for Image/Video editing with a little bit of gaming on the side. I named it "Red Flow" as I wanted to have a B&W build with Red accent on the cables (since cables are the components to transfer electricity, the "flow" in the system).

The Story

This build list took a long way and all the parts are finalized at last. It's my second personal build after 10 years. Coming from Q9550/P45/GTX 260 (upgraded to GTX 960) & 4GB DDR2 (expanded to 8GB), and having been using it from lots of gaming back then to mostly photo editing in recent years. As my workload on photo editing have been increasing and more video editing will soon be part of the family, it's time to have a brand new system to speed up my work (and occasionally some gaming).

Prices on this list reflect the amount I paid when made the purchase. Since the upgrade plan started back in March 2018, there's been a significant price difference on some parts I purchased when compare to the latest pricing. Especially the SSDs. I was originally planning on a 8700K/Z370 platform, started purchasing parts little by little, and brought the SSDs the week they were released. Then came with the news of Ryzen, then Z390, 2nd Gen Ryzen, and later the 9900K. So the wait game started......

Wanted to try on the ITX platform this time. Decided to stay with Intel and went with the 9900K mainly for it's processing power already available without OC. Although I may play around a bit with OCing from time to time (depending on the thermal headroom once I put the build together), it's most likely going to remain at stock speed, and it's another build that I may be using for another 6 - 8 years.

The choice with Phantom MB was mainly for it's features (especially TB3, although only at half speed but it's still the most feat. packed ITX mb available atm IMO).

Was planning on the RTX 2070, but decided to just go with the 1070 and upgrade when the 2nd gen RTX (or whatever they call it) come out as I don't game all that much nowadays. And thermal is also part of the concern.

Stress Test & Benchmarking (For Thermal)

Currently only tested on auto settings. This Phantom ITX MB pairing the 9900K @ stock pretty nicely, at auto it keeps voltage in the low 1.21v region when doing Prime95 (29.4 build 7) stress test with AVX enabled, runing all core 4.7GHz turbo and CPU Temp never exceeded 81C in Prime95 stress (no AVX offset, hottest core was 81C, and coolest one at 72C; might have to do with thermal paste application). RealBench stress test show slightly lower voltage around low 1.19v with same 4.7GHz turbo, temps were under 70C, and only around 62C when benchmarking (interestingly voltage went back up to 1.2v when benchmarking, but temps were lower). CPU temp well under 60C when doing Cinebench R15 & 3DMark Time Spy. GPU temps were kinda alright maxing at around 65C in 3DMark, don't know what temp it's suppose to be, but it doesn't seem to be a problem I guess?

Still need to play around with the fan curve to find the most suitable settings for my need. Though the whole system is pretty much silent or near silent during normal benchmarking, fans only spin up high when doing Prime95 stress tests.

Other thoughts so far

Currently the most problematic part in this build would be the Seagate HDD. Plan on using it as media storage, somehow it keeps making this "camera-shutter-like" noise for some reason when idling. No idea what causes it as the drive seem to work ok at the moment. Been using WD Blacks in the past, never had any failure and they run fairly quiet. Decided to give Seagate a shot this time, but well......hopefully it's not a faulty drive (could it be a setting issue?)

These replacement cables from CableMod are actually quite stiff, making cable management a lot more difficult than expected. Quality-wise, by taking a closer look on the way they make my custom length cables upon receiving, I don't feel they are as premium as some might say, but they do cost a premium for sure.

Why 1070 and 9900k?

Why not a 1080 + 9700k or 1080 Ti + 8700k?

But besides that, it's one of the most beautiful builds I've ever seen on here!

He probably had some reason to get the extra cores, say video editing and encoding

bloodroses75 1 Build 1 point 3 months ago

Image and video editing. Plus it's much easier to replace/upgrade a GPU later on than it is a CPU.

soulventic 1 point 3 months ago

Alright. Because If it was gaming strictly, I wouldn't of understood. But great looking and cable managed setup!

itx99k submitter 1 Build 2 points 3 months ago

Totally understand your point. Yeah, I'll upgrade GPU down the road as I almost don't do gaming nowadays. Just happened to found this 1070 for $300 buck and thought, why not, lol. However, a better GPU could benefit my work, say, in Davinci Resolve. Most likely will wait for the 2nd gen RTX or whatever comes up in 2 years or so :)

So Very clean!

Always love it when there's time taken to get some quality photos. Great job! The build is nice as well.

thanotosq 1 point 3 months ago

Very clean! Love the build! I'm putting some final touches on my h200i build now... Well, were final touches until I saw yours. Here's to another 3 days of OCD cable management...

itx99k submitter 1 Build 1 point 3 months ago

Thanks so much. It's always a challenge on cable management especially in smaller cases, but it's worth the work. Good luck!!!

Aside from your GPU bottle necking your 9900K, its a pretty dope build!

Great build and name especially. Cables deliver current to the system. The current is the rate of FLOW of charge. Nice man, guessing you like physics.

itx99k submitter 1 Build 1 point 3 months ago

Hahahahaha thanks man!

itx99k submitter 1 Build 1 point 3 months ago

Thank you guys for the comments!

Very nice looking build. Question - for the fans, did you replace the 140mm noctua fan that comes with the cpu cooler with the Noctua NF-S12A 120mm fan? What is the exhaust fan on the rear of the case? Then it looks like you have 2 fans pulling in from the front for a total of 4 case fans total? Any on top?

itx99k submitter 1 Build 1 point 2 months ago

I replaced the stock 140mm with the NF-A15 chromax version, and the NF-S12A as case exhaust fan. Using the two AF140 as front intakes. Currently only have that single 120mm as exhaust at the rear, no top fan atm. Temps seems ok, might add a top exhaust in the future tho, but haven't check clearance yet as the D15S is not tiny for this case.

rollin37 1 point 2 months ago

Thanks for the reply! I'm modeling my build after yours and will be doing similar things so this is helpful.

itx99k submitter 1 Build 1 point 2 months ago

You're welcome, glad it's helpful! And have fun with your build :)

Ericwanggg 1 point 1 month ago

How is the fit with the hdd and atx power supply? I am about to buy the h200i and have a 3.5 hdd and an atx psu so I am a little nervouc about the fit!

itx99k submitter 1 Build 1 point 1 month ago

They fit perfectly, there's more than enough room for both. However, I do recommend using shorter cables if you are using modular psu, as stacking a bunch of cables could effect some airflow in the lower compartment.

keyserr 1 point 1 month ago

Great work! Probably the most quiet HDD would be the WD Red 10TB as its helium and 5200rpm (and back it up with another one :))

itx99k submitter 1 Build 1 point 1 month ago

Thanks for the info! I may look into that in the near future :)

Did you have to update MB BIOS? If so did you have to temporarily use an earlier qualified CPU to do the update?

itx99k submitter 1 Build 1 point 1 month ago

No update needed. All 9th Gen CPUs are natively supported by Z390. You may need an update if using Z370 MB though :)

DanielleE 1 point 1 month ago

Thank you for the reply. The qualified CPU list does show different minimum BIOS levels depending on the exact CPU, however there are no BIOS release dates shown. I question this on the pcbuilder reddit forum and person said he had to update his BIOS, but the BIOS update worked with the i9 CPU.

itx99k submitter 1 Build 1 point 1 month ago

I see. I never checked on the qualified CPU list before building. Mine worked right out of the box though. Maybe the MB that were manufactured after certain date were shipped with a newer BIOS? Mine came with 1.20, and checking on ASRock's website it seem to be the first BIOS release? I did updated the BIOS to 1.30 few days after installing everything though, but nothing was wrong with the original BIOS :)
