Life is still stressful and demanding, but I'm trying my best to keep some form of momentum going. Still lots to do, but hopefully I'll have some more completed pieces to show soon: version 5 lighting rings should be next!

Thanks for reading and hope to be back soon!

Hey there. Might as well post some pretty renders of part 2 of the "seriously, haven't you fixed or discarded the DDC yet" saga.

With the pump assembly perfectly in place, it now transpires that I can't make the tube routing from pump to radiator through the floor to work without a stupid, ugly amount of adapters, and it's too tight for soft tube too and just kinks. So as suspected it's time to return to the custom pump top idea. Completely redesigned this time though. Enjoy the renders






I've extended the body width by 19mm to cover the distance between the pump body and the radiator holes in the case floor, so now an EK 90 degree rotary fitting will align directly above the radiator port's centre line, with sufficient vertical space to get a compression fitting on and angle some tube. That extension means I've gone down a distro plate approach to go from the volute outlet to the port, which has of course necessitated o-rings and a sealing plate.

And yes, the strong resemblance to Aquacomputer's DDC top is intentional; wanting to keep the look, I've drawn on many design cues from their dual DDC top to create mine as a homage to the top I've had to discard. I don't think I can get in trouble for that

To allow for measuring and manufacturing tolerances I will be using Mayhem's ultra clear soft tube for this part of the loop, but it's very clear for soft tube, 13mm OD is indistinguishable from 12mm OD acrylic when piped in, and once I have Oil Black Pastel coolant running you'd be hard pressed to tell the difference between the soft and hard tubes I think.

And I'm also very excited to say I'm discussing manufacturing of this right now. CAD models are being verified as I type

Update! Minor change of plan already

As I was fine-tuning the CAD work, I realised that I'd completely forgotten a fundamental point in this entire build: clearance spaces. And specifically, the entire reason I've been working and fighting with side ports is because I have zero space on the top face. So why in the hell did I put cap head screws along the horizontal centre line? They're going to foul the bloody graphics card! What a wally!

So as I was reworking things, it also occurred to me that as I'd gotten a bit carried away with replicating Aquacomputer's aesthetic, it would actually look out of place with my aesthetic. Countersunk screws solve both of these issues! So, the portion of the pump top that is visible peeking over the graphics card will have countersunk screws just like the GPU backplate. Also, my logo would be totally obscured by the GPU too.

So new model and new renders




But this IS getting made

OK, shortly after I posted last night I had a change of heart about the number of screws in the top plate. 6 started to look a bit cluttered, although I liked the symmetry of it. Since the top plate is 1.2mm stainless steel and won't flex because it's only 77x58mm in size, I remodelled to 4 screws instead. But because it's a slow day at work and I'm procrastinating, the 4 or 6 screw thing is bugging me. So I've done 2 quick layouts to illustrate (Fusion 360 in a browser is awesome!).







Looking at these without any lighting or textures and fancy projections, I think I'm actually satisfied with the 4-screw variation, it feels a lot more "open". The 6-screw symmetry is very nice but does feel a little cramped when I apply the graphics to the plate.

Any thoughts?

My guy did some CAM tests in acrylic for the internal structure.







Hot damn that looks good! So good in fact there's a small part of me regretting going black acetal for this. But, just like the cap head screws, however good this looks it doesn't fit with my overall theme.

Devil says "Except for the fact the SSD covers are a brushed metal plate with an acrylic light ring, and with the brushed stainless plate on top of this, it would actually look like the SSD covers if you light it up."
Angel says "Except the corners then wouldn't match because these are angled with a parallelogram motif and the SSDs are rounded rectangles."

NO! I shall be strong and stand by my convictions! And stop talking to myself!
