Dual waterblock

bigben2k · 05-21-2002, 03:07 PM

I REALLY like the spiral block from DTek, but I want to setup a dual Pelt (2*226W).

So I'm thinking about mounting TWO hi-flow spiral blocks on a cold plate/spacer. The problem is, how to I clamp (i.e. sandwich) those 50mm x 50mm pelts?

(Specifically, how do I clamp them down without blocking the prutty acrylic top, but put enough pressure?)

Cyco-Dude · 05-21-2002, 03:15 PM

well, you could do what DDen does to their blocks: drill some extra holes in the base and bolt the cold plate to the waterblcok (which sandwiches the pelt between the block and the cold plate). it looks like theres some room to play with on the edge if your careful enough and have a drill press...

bigben2k · 05-21-2002, 03:18 PM

Thanks CD.

The thing is, I don't have any dimensions on that spiral block. The good thing is that these blocks have a very big corner, so drilling it certainly wouldn't be a problem! (I don't have a drill press, but its not an issue.)

Does anyone have a spiral block?

schoolie · 05-21-2002, 03:28 PM

Actually, you can use the existing holes to attach a cold plate. The holes used to secure the lexan to the base go all the way through the block. The copper base of the spiral high-flow is 5cm square, FYI

Thanks for the info, but will a 50mm pelt fit within those holes?

Cyco-Dude · 05-21-2002, 04:01 PM

well, if the base is 5cm from edge to ede then...no lol
hmm...i wonder if there are high-power 40mm pelts you could use instead?
i dont suppose thermal epoxy is an option? maybe if you put the epoxy on, then clamped it *tight* while it dried...it might work (or it might suck ass, who knows hehehe).

WebMasta33 · 05-21-2002, 04:10 PM

You might wanna email Dtek about it. Last time I emailed them, they were very helpful.

bigben2k · 05-21-2002, 04:12 PM

I don't think I'm going to risk epoxying it, but then again... LOL!

No come to think of it, it bypasses the purpose of clamping:

I'm going to have to get very creative with this one... I e-mailed DTek already, no reply yet.

Of course I could always drill those holes right through the Pelt. Hum...

Mr. Thompson · 05-21-2002, 11:49 PM

Why do you want to run two 226 watt pelts? One will cool your CPU just fine. Unless you stack them, two pelts will only increase the load handling ability of the system.

Fixittt · 05-22-2002, 12:11 AM

Hey BIGBEn

Just for a FYI anything the maze series of block can handle, the Spir@l can handle. now as far as to 50 mm pelts, I think the mounting bolts will get in the way of that, on any socket a block.

Brad · 05-22-2002, 01:48 AM

bear in mind that 226w pelts are 50mm x 50mm. So you have 50mm x 100mm there already. Now lets say you need 5mm all around for the screws to hold the coldplate down.

you are up to 60mm x 110mm already. do you have that much room?

if you do, I'd suggest 2x maze1c-1's on a custom coldplate (get dden to make the coldplate)

methinks hes talking about the gemini spirals (specifically the high-flow version. u mustve missed that

)

ben, how exactly are you planning to use these pelts?? stacked? one for the CPU, and one for something else?

Yes, I am talking about the Gemini Hi-flow spirals (from DTEK). I want to setup 2 x 226 Watt Pelts, side-by-side. I'm going for an overclock of that Athlon XP 2200+, whenever it comes out.

Most importantly, I want to raise the FSB by 33, to 166. I'll be happy if I can get 166 FSB, anything else is just a bonus.

Brad: I really like the spiral configuration, and I'd rather try to make it work. (even if it involves a little custom work!)

As for the hold down, it will have to fit within the 50mm by 100m size of the cold plate, so probably the same setup as DangerDen, i.e. nylon spring bolts pulling the cold plate from the back side of the mobo (A7V333).

Now I'm thinking of drilling 4 holes in the 226W Pelt, to match those of the spiral block's cover. Not sure if it's a good idea, but the alternative would be to contact a manufacturer (?) and have them cut them up. I won't get 226W, but I don't care.

No reply from DTek yet.

resago · 05-22-2002, 09:10 AM

umm, you can't drill holes in pelts. Its made up of many tiny elements connected in series.

Well there goes that idea... Anybody know who makes those 226W Pelts?

bigben2k · 05-22-2002, 12:48 PM

I've searched and searched and searched... I found lots of info, but no manufacturer for that 226W pelt. Anyone?

I did find out that the Gemini spiral block is actually 2" by 2", and that the hole spacing is 1.675" (aka 42.5 mm) which could accept a 40mm pelt, bolts not whitstanding...
http://www.geminicool.com/images/big_CADCPUSpiral1.jpg

I got a reply from Danny@dtek: He says he hasn't received too many requests for running a pelt with a spiral, but that the lexan top overhang is very strong, if I wanted to use it for clamping. He kindly reminded me to check my mobo spacing.

He also told me that he's expecting a new spiral in three weeks, and that it would make things easier...

Cyco-Dude · 05-22-2002, 01:11 PM

then you might want to wait.
also, would it not be easier (and just as good, if not better since you have less load on the watercooling system) to use one pelt?

I could only use one... but that wouldn't be much fun, now would it?!?

I found the manufacturer of that 226W pelt:
http://www.huimao.com/series4.htm

It's in China.....

bigben2k · 05-22-2002, 01:31 PM

Now that I've seen the manufacturer's website...

I want that 260 Watt 40mm Pelt!

The only problem is finding a power supply for 3.5 volts max, at 100 amps!!!

Cyco-Dude · 05-22-2002, 01:55 PM

damn do0d...thats 1 killer pelt. would your house's electrical system be able to handle that?? ahhaha

methinks one pelt would be better. it would be easier to mount / insolate. it might actuallyt cool better w/ one pelt,. who knows (my reasoning is that a second pelt would heat the water up that much more, and peltiers are more efficient when the hot side is cooler (which it would be since the water temp is lower. this depends on your rad(s) tho)).

Well, 3.3V@100A= 330 Watts, yeah, I think it'll be ok.

As for a single pelt, like I said, it wouldn't be FUN!!! but then again, if I can't mount 2 50mm side by side, and knowing that the spiral runs optimally from the center so that if I use 2 40mm, they won't actually be side-by-side, which wouldn't cover the center (i.e. core) in a dual setup, then yeah, I'd use a single pelt.

So I'm thinking about a custom cold plate again, something with tabs maybe... Where's my vernier?!?

pHaestus · 05-22-2002, 03:25 PM

I would think that the primary consideration will be the dissipation of 600+W of heat. Even a single 226W pelt + TBird is getting well in the heat production range that is hard to contend with using water cooling.

I think Mr. Thompson knows a thing or two about big heat loads; I seem to recall his using dual 172s on a maze2-2 for a while. I also seem to remember something about huge evap cooling towers and really noisy fans perhaps?

bigben2k · 05-22-2002, 03:36 PM

and so I'm thinking that two big mommas, plus a chiller, could take care of that, but I'll have to do the math.

Cyco-Dude · 05-22-2002, 03:43 PM

multiple HCs in parrallel for sure.....heh, pretty soon your desk will start looking like Miss-Mans LOL!!

bigben2k · 05-22-2002, 03:53 PM

Yeah... and that 900 gph pump is starting to look good... LOL!
