9900K on mITX

Finally going to replace my Ivy Bridge system! This time around I really want to shrink the monster cases I've always used, and manufacturers are making some nice Z390 mITX motherboards now.

Power uses include some gaming (2560x1440) and a lot of crunching Blurays with Handbrake.

What cases would you recommend? And more importantly, what cooling would you recommend? I intend to go AIO water cooling, but not sure what mITX cases could fit the required AIO.

Thanks!
 
Phanteks Evolv ITX.
Phanteks Evolv Shift.
Fractal Design Define Nano S.
Raijintek Ophion Evo.

If you want something really small, with space for 120 mm AIO you can go for Raijintek Metis Plus.

You asked this question in wrong part of the forum, because you were not asking about the CPU, but the case for it 😉.

I like that Raijintek, and maybe even the Fractal. OK, cpu related question: what is the optimum speed ram for the 9900K? I've been out of the loop for awhile, so I'm assuming you can run any ram speed as long as the ram and mobo support that speed? Where is the point of diminishing returns for 9900K?

Not sure since there aren't any reviews out yet, but likely in the 3000 - 3200 range like its predecessors.

What kind of a silly question is that.

The 9900k ships with a cheap-ass fan and that alone is enough to cool it even as it boosts to 5ghz. WILL A GIGANTIC TWO FAN RADIATOR DO BETTER?
 
I didn't think this came with a fan, my mistake. Will that fan maintain the all core turbo of 4.3 (or is 4.6?) or only the 3.6 ghz at rated 95w TDP?
 
Parts on order! MetallicGear Neo MiniG case, Noctua NF-A14 case fans, Fractal Design Celsius S24 cooler, and of course other odds and ends. I'm excited, I've been using my Ivy machine for 6 YEARS!!
 
Still waiting on the cpu, but here is the build so far:

Question for you all. In a fit of confusion I bought two sets of ram to cover my bases, one 3600 CL15 G Skill Trident, and another 3200 CL14 G Skill Trident. I was unsure because of reports the 9900k IMC *may* be weaker than previous gen. I'm thinking of keeping the 3600 in case that isn't an issue, but if worse comes to worse, I should be able to downclock this to be identical to the 3200 correct? But are there more settings to change than just the typical handful that are always listed?

3600 CL15 is the better binning of the B-die memory.

I'd keep the 3600 CL15 over the 3200 CL14, especially with the small price difference. I have no trouble running 3600 CL15 (and a little bit more aggressive) on my i7-8700K so it seems like it'd be a major regression if it can't at least run 3600 CL15 XMP.

Worst case, 3200 CL14 should be a lock.
 
Well I need to decide which to keep soon, so I can get a refund for the other. So can I downclock the 3600 to the 3200 settings in the worst case?
 
From what I see, you use Seasonic Prime Titanium PSU. It HAS to be mounted with ventillating crate up, otherwise - you make yourself in HUGE trouble. The board to which everything in the PSU is mounted - will be heated up, and possibly fail after some time, especially in high current loads, and thermal output. It is very efficient, on low loads. But every PSU, especially fanless, will generate heat, and that heat has to be dissipated. And the only way for fanless PSU to dissipate that heat is by convection.

It's definitely not the fanless version though.

That is not correct. I have mounted it exactly as recommended by Seasonic's manual for my usage.

You might want to turn the hybrid fan control off(button in the inward position), that's what Seasonic recommend when the PSU is mounted upside-down.

Awesome system you're building, mind sharing a full parts list? 🙂

Oh, so it is not fanless. Then everything is fine. Fanless PSUs require to be placed vetillation hole upwards. If it is not fanless, then its fine.
 
So the rig is built and doing some stress testing to make sure everything is working well. I have the side of the case off so the Fractal Design Celsius S24 is getting as good air as it will ever get. Prime95 Blend maxes around 67C, but small FFT's is touching 89C on one of the cores. Thoughts?
