id order one now if i could.
i tryed placing a order with leufken today and got a answering machine. and dumb person me i believe gave em the wrong area code for my current phone #.
so if you have any news about availability post it soon pls. as i will be placing my order tomorow hopefully. w/leufken

that design your bud has is killer id love to give it a spin!
lol i said killer bud :cool:
anyhow i might even hold off on my order.

That dont look to good to me.I mean it looks neat and all but it appears like the whole system would cool only a video card.

I tried to get specs but site aint complete I guess.Do you have test system results,Water capicity,pump output ect ?

It just looks to compact and to contained with in itself to be efficient.

Here is Peter W. Eibeck email address. Email him and he will get back with you tomorrow. geminima@epix.net

Yeah I don't particularly like the setup either, first it's a spiral block, which I've never been to fond of anyway, and secondly, no split in the tubing from the rad to the CPU/Vid card. Instead the CPU warms the water and then passes it along to the vid card who warms it that much more and then to the chipset, then back to the resevoir. Also not sure if those vid card and chipset blocks are copper or aluminum. If they are aluminum... bad.

Interesting design. It looks like it might be a great "intro" to water cooling. Or maybe it could be used on your "backup" system?

[DodgeViper]

Before passing judgement give it a chance. He is a fellow O/Cer and did not just think this up in his sleep. It's been a project that has been ongoing through many changes and has arrived with what you see. If it did not work I do not think he would invest the money or time. Shortly he will have all the questions your asking on the website. I could post his emails that I have received, but that would not be right. If you have questions email Peter and I am sure he would be happy to answer your questions.

[DeltaSierra]

You're right Dodge. Sorry, I didn't really intend to be critical and it will be interesting to follow up and learn more about this cooling unit. Keep us up-to-date please.

[diehrd]

Click on the upper left part of the page where the company name is.From there you can read more about it.

My concerns are size of it.And as you read you find it sits in a cool place but I am sure you will ned some serious intake fans on the box you put it in.

I will look foward to see its test results.

[Silversinksam]

I wrote to them and asked if they could perhaps answer some of the questions you all asked....A true Overclocker friendly manufacturer would answer a fellow overclockers questions expeditiously ;)

Silversinksam, again give the man a chance. He has been up front with me and has answered every question I have asked. I am sure he has been overwhelmed by emails. He has stated that by weeks end he hopes to have a question an answer page.

[JoeCrappa]

i, for one, think that its a good innovation. its very appealing to the eye and i hope that it performs as well as it looks. i think i'll watch the progress on this. hopefully the kit is cheap.

[deathstar13]

hey dodge ty for the updates on this.
i mailed him also about aquiring this now. probly not available but gotta try.
as far as it goes as a kit i think it looks good. ive read others have their opinions about it also.
most kits ive seen are really bad and if some people would look at what other places are offering as a kit this one looks fantastic.

i do agree on the aluminum video blocks. i wouldnt get aluminum on anything but my case. unless they start making copper cases!.
oooooooh a idea :beer:
anyhow im gonna keep looking for updates and ill share what i can from my email reply later

[res0r9lm]

looks nice but dumps heat inside case me personaly I try to keep the amount of fan to a minimum

[Silversinksam]

Dodge,

I only wrote him today and I am sure he will get back to us.

I wasn't trying to be negative...:eh?:

[DodgeViper]

The heat gets dumped out the back of your computer case. Depending on the response he will offer the system in ALL COPPER.

That cooling system at geminicool looks great.

MAXXXXPERT has a product that is called CPU FREEZER.

-35c with 100W load
-20c with 200W load


Don't think its available in US tho.

US reseller, it will be available mid-Feb.

My only problem with it is, it looks like the hose from the condensor is WAY too short.

Interesting system...great for a ready made kit, I bet.

[Highlander944]

Hey guys, yeah this cooling system is my dream child...

I've been very busy trying to get all this information up on the website, but it's taking a little longer than I had hoped. I'll share some of my thoughts with you here....

Test system:
Athlon 1.4Gig @ 1.5Gig and 2.0V (100Watt heat load)
Vision Tek GF3Ti200 220/460
Epox 8K7A+ @143FSB

Temps:
CPU - 96F idle, 106 4 hours 3DMark2001, 109-111 4 hours Prime95
GPU - 97F idle, 100F, full load
Chipset - 99F

Config:
From Tank -> chipset -> GF3 -> CPU -> radiator
All temps taken with a DD5 and at TJunction.
All fans running at 7V and the system is QUITE

I've done a TON of testing. I started off with the manifold idea. Heck if you guys really want manifolds, I'll be happy to sell them. :-) The manifold I used had one in, 4 outs, and 1 fill port. Bottom line, if your pump is only 120gph, "faster' water is better. The manifold raised the temps.

I created this as a "system" it's tuned for a 120gph pump. As you can see, my temps are pretty good. Having said that, I'd also like to produce products that appeal to everyone. I'm planning on offering two spiral core designs. The first is my "normal" design, with a spiral cross sectional area of about .042in^2. And the second with a cross sectional area of about .070in^2. I'm also willing to produce the Vid and Chipset coolers in copper.

Some words of warning.... The Chipset and GPU are BIG. I mean compared to the CPU, the area in contact is HUGE. Thus, the Al does a very nice job of cooling. Do not expect the copper versions to do much better than the aluminum versions. If you use the deep spiral on a system with a 120gph pump you will see a minimum of a 10F increase in temps! Water has a great spacific heat, so you really don't need high volumes, you do need fast moving and only enough volume to absorbe the heat. This is actually ideal since the "lower volume" can sit in the radiator longer. :)

Hope this clears up a few of those questions....

Peter.

PS. I'm testing an XP setup very soon, so I'll try to get those results up asap. ;)

[diehrd]

Can you post in celceus.

I dont spell well but what the hall lol/

I am guessing 44c max load for 4 hours ??

[Highlander944]

haha sorry about that guys..

Temps:
CPU - 96F idle, 106 4 hours 3DMark2001, 109-111 4 hours Prime95
GPU - 97F idle, 100F, full load
Chipset - 99F

Temps in C:
CPU - 35.5, 41.1, 42.7-43.8
GPU - 36.1, 37.7
Chipset - 37.2

FYI.
Inlet Water temps at full load - 91F , 32.7C
Outlet Water temps at full load - 97F, 36.1C

[WarriorII]

WOW !
I really, really like his Tank/Rad design. All in one !
What a MAJOR space savings that is.
I'm putting a system together now, .....What a PAIN !:eek:
A major project it is!

You could use his as an entry level system. Then upgrade different components L8R.
That would be a KILLER system for a box w/ a window kit in it.
NEON GREEN. OMG !:eek: Black Light, the whole 9 on it.

Sweeeeeet. I like it !

I have always gone under the assumption that if it looks good:
it's a dog.
BUT if it looks like Hell, it'll stomp the doors off anything around.:D

Maybe times are changing?

Wonder what the $ is gonna be?

:cool:

[Highlander944]

haha... exactly!

Warrior is right on... the stuff is called die lite. I've gotten the literature from the manufacturer. It comes in at least blue and green. When under black light the water glows! That is the reason for the clear polycarbonate tops on the water blocks and tank. :) (that and as you may know, thick enough polycarbonate is bullet proof.. hehe practically bullet proof water blocks)

It's kind of pricey.. close to 60 bucks per pint. Good news is you don't need much.

I'm trying to keep my prices low. When I get some final numbers for you guys I'll post them...

[Silversinksam]

Highlander944,

Thanks for sharing your progression....I have to say your new system looks very sweet and I for one wish you luck in this endevour.

[UserName]

Why would you have a tank? Wouldn't you be better off with no tank and a larger heatsink?

Have you thought about using a coheasive blower instead of a regular fan?

[Highlander944]

Hey UserName,

There are several new ideas or at least ones i've not seen before on this design. I would guess they are patenable, but I don't quite have the extra $$ laying around to obtain one. :)

The water tank has nearly three feet of copper tubing inside! That tank by itself can cool a GF3 and chipset! So you see, it serves several purposes. 1) Extra cooling. 2) Water reserve for greater thermal inertia. 3) Houses the pump for more quite operation. 4) It looks cool. :)

As for the blower, yep I have one here. The problem is they are soooo noisy. The system really works well with the two 60mm fans running at 7V and blowing directly onto the extrusion. One large fan to push or suck the air through the tank is the only extra wind you need to get nice cooling.

The specs page is about done... I'll try to have it live by tonight.

Peter.

[UserName]

hoot suggested slowing them down, but i know what you mean. It seems hard to find a high quality one thats quiet even when slowed down. I bet if you slow it down you can get it quieter than the fan you got now and get better flow.

I understand about the thermal inertia. If you had to choose tho i think everyone would choose better cooling capacity over temporay thermal inertia.

Like in your system if you put two of your cold plate heat sink rads with the fins touching and the fan blowing between them you would double the cooling capacity in the same small format.

If you read the cooling article sticky at the top of this forum, it talks about rad design. 3' of tubing dont impress me. much better cooling with a parell flow system. Thats why a heater core kicks most rads.

[Highlander944]

Darn my reply didn't go.. :( Well since this is my second time typing.. I'll try to keep it brief...

UserName... been there done that. I started off just like you said, thinking I'd put the two sinks together. Well I quickly discovered that there is a point of diminishing returns with respect to length on those extrusions... As it turns out, the turbulent air that is generated by placing the 60mm fans directly on top of the extrusion does a MUCH better job of cooling than the blow does/did and they are more quite.. even if the blower was turned down.

Second, the water tank is a kick butt design.. if i do say so myself. :) That thing has nearly three feet of copper tubing installed! The extra water "sits" in the tank longer and allows further water cooling... which as we all know, is best for all radiators. The water tank alone is probably good enough to cool an Athlon XP 1600+ by itself. I know, 1st hand it can cool a GF3 and MB Chipset.

You have some good questions... I spent quite a bit of time doing math before I began machining the first designs. Where the math was "fuzzy" I found that tweaking the design through testing worked well. I have about 20 pages of excel spreadsheet with all the plots and equations. I'm glad to see that I thought of all these questions in the design phase and didn't get this far and find I missed something... That's not to say I thought of everything so please keep it coming.

ttyl,

Peter.

[Trieber]

Dude, looks great. It has that new look, not bulky, all 1 compact piece. Very nice looking and the price is pretty good compared. As for ideas, I don't see any, I think everyone got them covered here lol. Good job though.

[diehrd]

I am wondering what its total cooling capicity is.Is it rated to cool 100 watts of heat? 300 watts of heat?

Also I am curious if the system tested was in a case or in a bench.If in a case can you state case specs?

Also it seams to cool close to the temps of a good air system.So what is its cost ?
