Just starting work on a TEC/Chilled Water cooler and I received the Lytron heat exchanger today. All I can say is WOW...awsome build quality. 100% Copper/Stainless Steel construction. 11" x 20" of copper cooling power. :)

Blimey, look at the size of that thing :D

What fans you putting on it?

How far away from the core is that shroud?
Looks way too close to me, id want to cut that off and make a propper shroud.

What other components are you using?

Lytron makes the highest quality stuff period.

Only thing I see about it is its huge, but still uses tube not flattened lines...

What fans you putting on it? I will be using two high performance automotive radiator fans that push up to 1700cfm air.

How far away from the core is that shroud?
Looks way too close to me, id want to cut that off and make a propper shroud. I didn't measure the shroud and I'm at work now, but I believe it was about 1.5" from the core surface.

What other components are you using?As far as cooling components it has dual continuous duty 1/6HP sump pumps moving 1400gph each. One will service the CPU/Chipset/System Memory, and the other will be dedicated to the graphics card. There are 4 TECs in the system, 1x350w, 3x320w. The fans I mentioned above. I will also be using four Swiftech blocks, and a Danger Den chipset block.

If your using those fans that shroud will probably work very well.

Cant wait to see your finished system .... its going to be the extreme end of xtreme :D

Are you making some crazy 3x320watt CPU cooler?
More detail please !!!!

Crazy 3x320 watt? Thats nothing! With a big heat load from peltiers radiator-to-air heat exchangers will never keep up with bongs!

Srry for the spam, had to say it.

Avid6eek

The heat exchanger is large enough to keep up with the heatload without any problems. On top of that this exchange system will be mounted outside of my house. Given that I live in upstate NY, our average annual temperature is 46F. Now that we are going into Winter, temps drop as low as -40F. The end result will be liquid that is well below freezing cooling off these monster Pelts. The pelts have a minimum operating temperature of -60C and I should have no problems getting close to that given the liquid temps may be as low as -30C.

350w TEC - System RAM
320w TEC - Processor
Dual 320w TEC - ATI X1800XT

Hehe thats a monster tec system. Why not 437's? More efficiency if you run them a bit lower.

Yep, TEC on the ram wont help.

Others have tried it with minimal success.
I gained nothing when I freeze sprayed my ram.

Double up the pelts on the CPU if you can ... this will be much more effective.

Avid6eek

10-31-2005, 02:14 PM

ooooh, upstate NY (me too), whereabouts? If outdoor temps of -40, i'm gonna take a stab and say either adirondaks or watertown area...
you're putting a 350watt (320watt did you mean?) TEC on your RAM? thats just sooooo overkill... double up on the CPU :) Adirondaks :)

I am using the largest Pelt on the system memory because the cold has quite a bit of copper to travel through. I will be using Muskin Redline memory which requires active cooling to reach it's stock specifications. Additional cooling can only help. I prefer performance from lower latencies at high clock speeds instead of extreme clock speed with slower latency.

I gotta argue that. TEC's on ram do work quite well for shoring up tighter timings at a given setting. They don't improve your fsb by much though normally. And double up on cpu if you can as well. But run the tec on the ram at half power. The efficiency's were its at.

Nice Block! here's some criticism. Less copper, and at least half as thin! Especially the part tec is on. Id also say.... Sweet use of 6002's!

Avid6eek

10-31-2005, 02:16 PM

Double up the pelts on the CPU if you can ... this will be much more effective. If I find that my CPU needs more cooling than a single 320w TEC, I do have a set of chilly1 containers and an empty dewar laying around :D

oh my, I'm envious.
Whereabouts in the ADKs? I vacation up there quite regularly and my grandparents live half the year up there

oh and no 40mm tec on north bridge??

oh my, I'm envious.
Whereabouts in the ADKs? I vacation up there quite regularly and my grandparents live half the year up there My full time residence is in Amsterdam, NY, and we have a camp in Speculator, NY.
oh and no 40mm tec on north bridge?? The northbridge is going to be cooling with just chilled water before on the same line as the memory...before the water reaches the memory TEC though.

The reason I didn't go with any larger TECs was because I couldn't find them on eBay. I bought each of the ones I have now for $15 which is considerably cheaper than Danger Den.

Yeah, I'm looking into finding a supplier or builder of peltiers with high quality semi-conductors.

Avid6eek

10-31-2005, 03:05 PM

Speculator, no :banana::banana::banana::banana: eh? lake piseco for me for a few weeks in the summer :)
15 bucks a pop? gotta love ebay. 437 watt beasts are availible over at frozencpu, but for a pretty penny of 50 bucks a pop. The adirondaks are a beautiful place during the summer. I'm up there camping as often as I can during the summer.

For $50 I'd rather have 3 x 320w Peltiers than a single 437w version. FrozenCPU is marking them up quite a bit.

Bloody_Sorcerer

10-31-2005, 03:26 PM

yeah, frozenCPU tends to do that. Even so, wintsch labs used to sell them for like 45 bucks, so it isn't too huge of a markup; things just tend to be dirt cheap on ebay :)

n00b 0f l337

10-31-2005, 03:40 PM

Yes. But if you do use multiple peltiers, efficiency is were its at. Run them at half power!

looks cool.

Can you please provide a comparison between

Ram without fans.
Ram plus fans (80mm sat on top or similar)
TEC cooled to -50*c (it might get even colder)

Very interesting to see what happends with this ram cooling .. I dont think anybody has tried it like you are.

I hope your an insulation EXPERT .. this is going to cool the ram and motherboard as well I think.

Holst

11-01-2005, 07:50 AM

Oh ...

I notice that you have not yet designed the holddown for the ram waterblock.
Try and get the clamping pressure as high as you can .. TEC like to be squeezed.

Avid6eek

11-01-2005, 09:46 AM

The design of the RAM block hasn't been finalized because I haven't picked a motherboard yet. I need the board so I know how far apart the memory modules will be.

I can forsee condensation dripping into the ram slots or am I missing something?

I agree that top surface of the mem chiller is fairly large. Most of that unit will def below ambient wouldn’t this cause an issue. With a motherboard mounted vertically you can have condensation dripping any where.

Insulted properly this wont be a problem.

But it will be a challenge to insulate it well, but you can do it if you take your time.

Avid6eek

11-03-2005, 03:54 PM

I have a large box full of various thinknesses of neoprene. It will be insulated. Of course I don't want water condensing on the block, be even more importantly I don't want heat to get in.

That ram cooler is totally uber-cool. Perhaps youll put another 320w pelt on chipset and use di for cpu? Or is this going to be a 24/7 system? :D

More Pics. The cooling unit is starting to come together nicely. The more I get built the more excited I am getting about finally getting this thing up and running. Still going to be a few weeks until I am able to, but the time will go by fast.

looks cool but the fans look like they would be really loud!

Avid6eek

11-07-2005, 12:13 PM

Yes, the fans are extremely loud. The PSU's I'm using for them allow me to adjust the voltage from 11v to 13.5v. At 13.5v the fans are really moving. This unit is going to be outside of my house, so I don't care how loud it is.

Avid6eek

11-07-2005, 04:54 PM

Getting into the final stages now. Covering the whole thing with some weather resistant board...basically the same thing dry erase boards are made of.

Just starting the edging.

A picture of the 150w 11-13.5v 12.5A PSUs I'm using to power the fans and my TECs. I've got 14 of them which should provide me with more than enough power.

I haven't posted any updated pics in a while because I've been using all my free time to build. The external cooling unit is done, and now I'm working on the internal system.

From the inside:

I am going to have 4 cooling lines...

Line 1 - Processor (350w Peltier)
Line 2 - Chipset / System Memory (320w Peltier)
Line 3 - Front of Graphics Card (320 Peltier)
Line 4 - Back of Graphics Card (320w Peltier)
