My New WC Layout. Any Comments or Suggestions? Mostly Heatercore Related.

I currently have a '77 Bonneville heatercore in a full tower (in the bottom front). It's about 240mm x 160mm. I'm sure most if not all here are familiar with it.

I was planning on using this heatercore for my new rig, but now I'm thinking about a new layout. I thought it up mainly from some of my previous designs so I guess you would say it stemmed from an evolution of ideas. It's a rather simple idea, though I've never seen anything like it online. Basically a external rad box attached to the bottom of a mid tower resulting in full tower dimentions. (And a "reseratior")


Would two ~120mm x ~120mm heatercores be better, worse, or about the same from a performance standpoint? What about three? And which of the many heatercores of this size would you personally recommend? Edit: With just a rought guestimate max heatercore dimentions come out to about 180mmx160mm.


Here's part of the setup. I added the third heatercore & fan for good measure if only so I can undervolt all the fans all the more.




I may turn the hottest heatercore around such that the fan is sucking like all the others. I plan on using birch ply (Light but strong. I use birch props on my RC airplanes) for the rad/pump box.

So turning a mid tower into a full tower, just one with the attributes I want, which is a full tower with lots of room at the bottom. The only case I know of that might let me do this layout without serious modding would be the Coolermaster Stacker. But I would like the look of a Lian Li and their full tower just has a lot on 5.25” bays and very little if any of the extra volume is in the bottom area where I would like. I could put a Camry heatercore in the 5.25” bays I know, but I would like them towards the bottom, if only for aesthetics.


That’s one thing I like about this idea is aesthetics. Not only is the Iwaki hidden (sticks out like a sore thumb in my current full tower), but the cool looking action (UV additive) tubing, waterblocks, and reservoir (if I use one) are literally placed on a pedestal rather an at the bottom of things.

Also, I plan to make this slightly on the wide side so I could use it in future rigs to come.


I hope to make this setup selectable from a very quiet machine to a near silent machine with only the PSU fan and outblowing rear case fan running (and of course the Iwaki). How? More sketches coming...

As part of the "near silent" selection, I plan on using the quickconnects UncleBob is using with his setup (link) and attaching a nice big copper reservoir to act as a reseratior.

Here's a few shot's of UncleBob's Setup (for those of you who haven't seen them.


http://img.photobucket.com/albums/v2...t/dscn0016.jpg


From these quickconnects I plan on hooking up a large uninsulated copper cylinder like the old direct hot water cylinders. Something about 8"x26” (.20m x .66m).




Essentially I would like to use this as a reseratior and simply turn off all the fans on the heatercores, expect perhaps the rear one in the bottom enclosure to keeps some air passing over the Iwaki. And if I ever would like to take my computer to a lan party or something, I’ll have the cooling power with three heatercores and can just leave the hugh water cylinder at home.



What do you guys think? Comments, suggestions?

Those are the same fittings I'm using on my external system. You might find them a little cheaper over here.

Cool, thanks. How restrictive are they?

They are somewhat restrictive, but not as bad I thought they would. I really didn't do any in depth testing on them ie: measuring flow and pressure loss. What I did do was do check my CPU temps without them installed and with them installed and only came up with was a average of 1c differance between the 2 setups. It's not that big of a deal to me as the ease of disconnecting, transporting and maintaining the system are more than worth the 1c higher temps.

These are the ones that I used on my system.

60695 1/2" Polypropylene Bulkhead Panel Mount Hose Barb Shutoff- 2.82 Lgt - Coupling Body

If I went for the 5/8" size I should still be able to fit 1/2ID in it, right (hot water trick)? Correct me if I'm wrong but the 5/8" would be less restrictive than the 1/2".

From this thread in the case modders section:

Colder also makes a beautiful aluminum 5/8" flow FL series which they state is their "highest flow, lowest pressure drop, valved couplings offered by CPC", but it is in-line. Good Luck!

Any comments on this? 3/8" ID would be a bummer.

Those larger ones would be great to have, but I already have a mortgage on my house, so I got the largest I had money for at the time. I have to keep reminding myself that I'm a retired disabled vet and cash can get a little tight at times.........

Hey, that's totally fine. I haven't even looked at the prices yet myself so I don't know what we're talking about dollars wise.

Would three ~120mm x ~120mm heatercores do me just fine for just about anything?

Something like running an A64 3000+ at greater than 3700+ speeds @2+v, a watercooled northbridge, and an overclocked 6800 Ultra or maybe two with SLI? Or would I have to use two 120x240 heatercores with a pair of car blowers to sufficiently handle this load?

Not that I’ll necessarily have such a significant wattage setup right off, but I’m really thing about this for the long haul i.e. I would like this quasi-external setup to be used as-is for the next half decade or so.

Max Dimensions:
242.8875 x 495.3 x 649.288 mm (WxDxH)
(9.5625” x 19.5” x 25.5625”)

Preferred Max Height Total: 25” ≈ 635mm

Birch Ply ½ in. Thickness: 11mm

Approx. Case Max Height: 17.7165” ≈ 450mm

Concluding Support Box Dimentions:
Exterior Dimensions: 242.8 x 495.3 x 185 (WxDxH)
Interior Dimensions: 222.8 mm x 163 mm (WxH)

So my max heatercore size with the above dimensions would be 222.8mm x 163mm x Depth” ≈ 8.77” x 6.417” x Depth”


Would it be too restrictive (air flow wise) to put three 2" heatercores in the bottom quasi-external rad box. Perhaps three ~1" heatercores?

Oh, by the way, the components I plan on using.

Pump: Iwaki MD-20Z
CPU Block: Cathar's "Storm" G4
Northbridge: Silverprop or perhaps a Maze4
GPU: Silverprop
Tubing: Tygon R-3603 or Clearflex60 1/2"ID or 7/16"ID
Heatecores: Not sure yet
Heatercore Fans: Papst 4412 on the heatercores, perhaps Globes or Nexus fans
Case Fans: Globe or Nexus fans

Any thought on this?


Also, can heatercore orientation give you trapped air issues? I heard of one case where an inverted heatercore prevented proper bleeding.

I ask because I may end up laying the heatercores on their sides. My thought is that it will probably be easier to find a 8.77” x 6.417” (HxW) heatercore and just lay it on its side than to find a 8.77” x 6.417” (WxH) heatercore.


Big thanks for the help,

DrCR
