[Build Log] Freilite Brevis S - GTX 1070 and FlexATX in a <5L package - Page 8

Wow! Actual metal and wires and stuff! Good work!

Hope you get the replacement PSU soon. A misbehaving 40mm server room fan should never be allowed past the soundproof walls.



Really like how you covered the drives and noisy power supply with a chic blanket. That's very thoughtful and cozy. biggrin.gif

I won't nitpick about the cable management issues. Is the surprise twist in this project the mandatory additional 5L case just for cabling ;-)

Great to see you making big progress on your project. Congrats!

Super stoked to see this come together. I had to get a Thermaltake cube case that I am not the least bit happy with. Being able to mount my PC to the back of my monitor or even my 50 inch 4k TV would make me squee. If you do a Kickstarter or something, I'm down for at least one, possibly two.

Edit: I have an i5-4690k. If I only have roughly 38 mm for cooling, I'm going to have a bad time, aren't I?

Thanks guys/gals!

I actually have a solution for that which should make the insides of this case extremely tidy.

Glad to hear it! Jup I want to support VESA mounting and there's a concept for how this could look a few posts back, I think.

It depends on how hard you push it, but yeah the CPU cooler is going to be quite loud if the CPU is at full load. Alternatively, I also thought about an open-air side panel. With that you could install any cooler you want.

Aibophobia on SFFn mentioned the width he used for the PCIe slot for the KI Cerberus, the distance from the mounting flange from the mounting flange to the cutout is 7mm there. So I checked my GPU and yes, 7mm would've been enough, just about. I was at 9.5, but that's fixed now.

For my current prototype, I crudely corrected it:



I also mounted the SSP-300SUG and as I expected, it not adhering to the FlexATX Standard by makes it fit awkwardly and it can only be mounted with two screws.. I'll have to correct the cutout to be a bit taller.


Either way, the SSP-300SUG is wonderfully quiet in idle.

Right now I'm running it without a dGPU, but it makes for a lovely compact rig, too:



Which makes me think whether this could be made modular. Like having the frame as three separate pieces (MB, PSU, GPU) and being able to combine them however you like. Another idea would be to have a way of making the case thicker with an additional piece to give space for taller CPU coolers and more drives if desired.

Oh...bigger coolers...got my attention. The modular concept could be great. Especially if you could have it manufactured in inflatable aluminum*. Finally, one size fits all. biggrin.gif

I know, a lot of people would like to use bigger coolers than the NH-L9, and it's an absolutely viable request for beefier CPUs.
That inflatable aluminium thing can happen if you've got a few billion dollars to spare for the research cost wink.gif
post #77 of 86
Only a few billion dollars??? This deserves an inflation-able R&D budget!

When you say bigger coolers? How big is bigger? 74mm or 148mm or 162mm? Or unlimited for those of us with...

Well, with the modular approach, the thickness would be increased by something like 15-20mm when adding a vertical module, so you'd be looking at 52-60mm of CPU cooler space. Of course it could also be designed to be stackable, so if you want even more height, you can just add another module or a few washers below the side panel to gain a few more mms.

With an open-air side-panel (which would look like the current one but empty space instead of vents), the space for coolers would be unlimited indeed, so you can even mount a monstrosity like this. You could also go for a fully passive build by using two CR-95Cs or something crazy like that. The more I talk about it, the better it sounds. wink.gif

Update time!

The cable harness for the SSP-300SUG was completed in two sittings. I used pins and connectors from Icemodz, which are very, very nice connectors BTW. The 6+2 pin PEG and 4+4 pin EPS12V have a particularly nice feeling to them. They just fit together so very well. Here's how everything went:

First off, all the tools I needed for crimping were at work. While I don't trust the GPU construction yet, the main frame was just put inside my messenger bag with no further protection. Perfect plan. At least it showed how much easier this case will fit than Freilite Alpha once it's completed.



Progress after day 1:

Transportation went flawless, I got my wiring chart setup, but I wasn't really focusing on making it beautiful. Just a somewhat good-looking proof of concept that I could use to test every component combination, no calculation of wire bends and stuff like that.

After day 1, I already had the 4+4 pin EPS 12V, 6 pin PEG and 6+2 pin PEG cables done.



Of course the PEG connectors are not planned to be used in full configuration, no ITX GPU has an 8-pin and a 6-pin connector. But both two 6-pin and a single 8-pin connector are common and able to deliver the same wattage, so I had to accommodate that somehow. Here's my solution:



Looks a bit dodgy at first, but the PSU has very few pins available, the 12V for the PEG connectors are just on two pins. The pins should be rated for 13A, so at a maximum rating of 312W I'm way above the 225W an 8-pin connector (or two 6-pins) is rated for.

It gets a bit dodgier when we look at the EPS12V cable:



This is just connected via a single pin, so the maximum power rating for that connection would be 156W. In theory, an 8-pin EPS12V connector is rated for more, but you don't want to use any CPU over 88W if the biggest cooler you can fit is an NH-L9i. This would be different for APU builds that utilise an AIO in the GPU compartment, so those would have to use a PEG-to-EPS12V adapter or get a different cable harness.

Progress after day 2:

Everything's done! I did put a little bit of effort into the ATX cable to make sure it would at least somewhat stay in this shape, but you could certainly do better. Either way, it's a large improvement over the previous situation.



In this picture, you can already see the PC light up, but it wouldn't actually POST at this stage. No display signal, and no speaker header for troubleshooting. The problem was that I didn't make a connection for the -12V rail. This was deliberate, as the FSP500-50FSPT was once considered as a bundled PSU with this case and it lacks the -12V rail, but apparently some Mainboards are checking every voltage before POSTing properly, so that option is pretty much out the window now. After crimping the last wire, everything worked out fine.

I also removed the blue LEDs cables from the power button while I was at it.



And now it's sitting on my desk, looking a lot nicer already:




I tried to resolve the slanted GPU by chaining the HDPLEX and LiHeat risers together, but I didn't get a display signal with that. Next thing to try is testing two HDPLEX risers chained.

First tests with the new PSU:

So as a simple first test, I just ran Unigine Heaven for 20 minutes or so to see what the new PSU could do. It's actually pretty darn quiet for something with a wimpy 40mm fan in the back. It didn't get any louder than the GPU itself, as long as the exhaust was unobstructed. The fan is not exhibiting any high pitched whining, just the whooshing noise of air turbulence. In idle the GPUs fans are much more audible than the PSU, so that's certainly a good thing.

Interestingly, it took the PSU a lot longer (about 5 minutes) to ramp up its fan to maximum speed when running the benchmark than the GPU (about 25 seconds). With a highly professional temperature difference measuring device called "finger", I also confirmed that the side of the PSU close to the GPU was much hotter than the one close to the CPU. I'll have to see whether that is actually caused by the GPU exhausting or whether the PSU has a natural hotspot in that area.

I've also taken measurements on the PSUs non-standard-compliant power connector and will post the results of that in its respective review thread.

As a bonus, here's a picture of my dog sleeping in a chair. Thanks for reading!

Great update! Sweet puppy too! Possibly a little bored with your progress - seems like the perfect critter for wire herding tho. biggrin.gif

So, do think this Seasonic will be the best quiet Flex power choice?
