Igloo Cooler

[JToolz]

What can I use for the resevoir for my chiller setup? I want something as small as I can get with good performance? Thank You

[TheDude]

Either a small igloo or you can make your own any size you want. You just must make sure that it is very well insulated. Opp used a big igloo for a long time...smashed a lot of records with his old chiller.:D
I saw it up for sale...should be donated to a museum.:D

[Keeper]

That Chiller is still usable, and won't be making the museum scene quite yet........I am making it an office showpeice for "Nerds for Jesus", so with some help from the man upstairs it just might have a few more records left in it :)

And yes he did use an igloo.

Cool....I didn't know you had it Keeper.
Glad to see it's still in capable hands and will no doubt continue to set new records.:D

[Keeper]

I don't know how capable I am, but I am learning alot thanks to this site.

I am testing it right now as we speak, I built a form around the dryer and foam insulated it, beefed up insulation (with the help of rubber insulation from the local refrigeration people [ and they gave it to me free too being this is a Church project]) every where else including the regulator.

This one (thanks Oppainter) is so charged up, I was getting condensation on the compressor itself. Some rubber insulation tape on that (about 2”X 1”) area is now condensation proof.

The chiller has been running for hours and no condensation anywhere.

A cabinet maker is building a case for the chiller for me that should be ready in a couple of weeks. In the mean time I am doing some case mods so I can have access to the back of my MB making insulation of the CPU and NB more accessible.

WoW....that's going to be really nice when you are done!

Good deal Keeper, looks like you may have optimised much better then I had it. I did have a Shroud around the fan though, it blew directly on the Compressor to cool it a tad, got a degree or 2 out of it.

OPP

[Keeper]

On the case for the chiller, the registers will be positioned to force all the air to go by the compressor before leaving the case. So I will be taking advantage of those 2 degrees as well.

All tips are welcome, you guys are the best………and I didn’t even own a soldering gun until I started reading this board.

[Keeper]

In this step I have installed the mother board; the north bridge heatsink has been removed because it will be water cooled.

In this pic you can see the neat holes cut by Jack, and then gromac-ed to protect the insulated hose that will be supplying the chilled water to the water blocks.


http://www.nerdsforjesus.org/images/177.jpg


Here you can see the modified back of the case. I did this so I could have extra room and access to the back of the motherboard to insulate it against condensation. You can see the holes make the back of the motherboard accessible to both CPU and Northbridge.

More to come………..

[TerroH8er]

Pretty sweet setup you got there Keeper, looks like a lot of hard work went into making that, can't wait to see the results! :)

[bowman1964]

looking very very nice.

[TheDude]

VERY nice indeed, looks like you thought it out before hand.:D

[Keeper]

Well I just got word that juaquin has finished my chiller case.

Here is what it looks like;

Looks like drilling a couple of holes for the hoses, mounting some wheels, and a power switch and we are ready to Chill and Clock.

Thanks a million juaquin

[edesignuk]

OMG, that's friggin HUGE! :eek:

[Keeper]

It 16" wide, 30" long, and 21" high. It looks bigger than life in the pics.

[Keeper]

I am now testing the chiller with fluid in it; it is a combination of widow washer fluid and isopropyl alcohol.

http://www.nerdsforjesus.org/images/59.jpg




I checked it every 30 minutes for three hours; it seemed to level off at -25C

http://www.nerdsforjesus.org/images/chillertemps.JPG

I am about to go to bed the temp is at -26.3C

[Pimpsho]

thats pretty damn good man also what kinda coolant u usin?

[Keeper]

I am using windshield washer fluid, but down here in Texas the best fluid I can find is only -35 proof, and it started to slush at -34 today.

I am pretty sure once I put this under load it will never get that cold, but I am still a bit concerned about the viscosity of this fluid at -20+.

[Pimpsho]

viscosity? is that how well it dissapates heat or how like thick it is....

[Keeper]

How thick it is, and this stuff is just too thick at freezing temps to get a reasonable flow rate. I think I'm going to end up putting alcohol in this chiller. I can't find any good methynol products in my area, never freezes down here.

[Keeper]

She is up and running, working on WU #2 @2700MHz, not bad for a XP1700. I don't want to jump the gun, so I will post some bench's after some more burn-in;

http://www.nerdsforjesus.org/images/1700@2700.JPG

[Pimpsho]

NICE what kinda temps we lookin at here?

[Keeper]

The CPU runs at 10 to 13C under load (folding), seems a bit cooler right now fluid temps a steady -21C. I could probably get better temps, but I am cooling the GPU with the same chilled fluid.

[Pimpsho]

wow thats pretty high arent they for that kinda cooling? what water block r u using? r u using a tec setup or just straight water cooling? cuz thats what i get almost with my ambient water with my tec setup...

[Keeper]

This is my first xtreme cooling setup, and I am doing straight cooling with waterblocks only. I am using innoveteck blocks, their regular GPU block and the new CPU block.

This is day three and the CPU is at +5.50 using Hardware Doctor. I was in the BIOS today and the temps in there were -11C, so I don't know what the real temps might be. Someone might give me a link to a good MBM and then I can know what temps I really have.

After I recover ($$$$) from this project I can think out a tec addition, but for a while I am stuck where I am cooling wise.

Right now I am trying to figure out how to set the BIOS to run the FSB over 200. There are so many options on this board it's scary to a newbie like me, and with all the dead bios stories it is even more scary.

[Pimpsho]

ya! well im sure that when u get your tec setup u will be hitin the -5 and lower and prolly get 40-50 more mhzs stable outa it!

[Method Man]

Looks awsome Keeper :rocker:

[Gary Lloyd]

Pure methanol is used for gas line anti-freeze, and is also a fuel for model airplanes. Methanol/ethanol mixture is used for paint stripper. Hopefully, one of these may lead you to a source.

Also, with condensation on the bottom of the compressor, this would indicate that the system may be overcharged.

/me waves back @ JR

Thinking this is my kind of forum. :D

[baker18]

Welcome Gary,

Your expertise will be a valuable asset to this forum.

[Keeper]

Gary, I am using 182proof alcohol right now.....I picked it because it was not static sensitive and its viscosity does not change at below freezing temps. I am wondering what the best fluid would be to remove heat and still maintain a decent flow rate. I tried antifreeze and window washer fluid, but both became too thick for good flow.

Once I put this unit under load all the condensation near the compressor stopped, even when fluids dropped to -35C. I did have to make my reservoir air tight, but I new that needed to be done no matter what fluid I used.

At idle this set up will go -11C, but who wants an idle machine.

[Gary Lloyd]

Thanks, Baker. :D

Keeper, methanol and ethanol are types of alcohol. The downside with all alcohol is flammability, and some are toxic as well. Be careful. There is some discussion over at phase-change.com of using calcium chloride, but the jury is still out on this.

At idle with lowest temps, there should be frost on the suction line almost to the compressor. This gets you in the ballpark.

To really fine tune the charge, at idle with lowest evap temp, we would need the following:

Evap temp
Low side pressure
Suction line temp 3-6 inches from compressor
High side pressure
Cond air in temp
Cond air out temp
Liquid line temp 3-6 inches from condenser

[Method Man]

Keeper go get yourself a powerful Iwaki pump, a MCW462-UHT, and some Clearflex 60 and lets see that suckaz true power!!!:rocker: :rocker: :rocker:

[Keeper]

Thanks for the warning Gary, actually one of the reasons I went with alcohol was the fumes business; I don’t like odorless toxic fumes. I have worked with alcohol, and although it is flammable; at least if I have leakage I will smell it. I have no leakage at this point. I am going to need better reading tools for fine tuning this thing, but it seems to be well charged (this is Oppainter’s old unit). This unit is definitely “in the ball park”, I have seen the fluid drop to -35C at idle, and then I turned it off to make sure I was condensation proof. When I fired it back up I did it at room temp and put it under load; the fluid temps are at -23.9 with 100% CPU load and hardware doctor claiming a CPU temp of +7C. I suspect I will be going to tec when I recover from $ spent on this one.

Method, I will be looking at a MCW462-UHT, and thanks mod on this board, I’ll bet you were wondering when I would have it up and running; seems like it took forever. The truth is; I was afraid I wouldn’t be able to condensation proof this setup and just had to get the chicken out of me.

Ya, I was wondering when you were going to get it all up and running....and now you got it up looks great man good job :thumbsup:

[Pimpsho]

hey keeper got ne close up shots of the case? with the stuff all inside?

:slobber: :slobber: :slobber: NOW THATS WHAT I CALL CONDENSATION PROOFIN!! LOL MAN U DIDNT GO LIGHT ON THE DIELECTRIC GREASE EITHER:D

[Keeper]

It was my first stab at going xtreme, and I didn't want any leaks. Now I can play around with the settings;

[st0nedpenguin]

WOW!

I hope this kind of extremity isn't expected of all newbies. :D

/me begins to cower in fear.

[]JR[]

Keeper where did ya get (and what is) that pipe lagging?? The stuff ive just tried is rubbish and need some better stuff?

]JR[

[Keeper]

Thats rubber lagging I got at the local refrigeration repair outfit in my area. It is seamless and works great. They gave me about 16' feet of it, much better than the foam type I worked with earlier.

Next time I drive by, I'll ask where they get it, and post it here.

[]JR[]

Ive ordered some armaflex closed cell refridgeration lagging good to -50C apparently was cheap £3/$5 for 2meters so its ok!

Good luck with the chiller :banana:

]JR[

[Keeper]

This stuff can't cost much, they gave it to me and it was the first time I ever walked into the place. But the shop I went to does repairs for all the major grocery stores here in El Paso and must get it by the roll.

I am only fearing the electric bill right now, thanks all of you here at Xtremesystems...............I have been inspired by all of your work here.
