if you get to the point of boiling water there are gonna be other serious issues that will matter more than the steam..

i remember seeing here on XS (i think) or maybe Tom's that 3M has a liquid that boils at a relatively low temp and they demonstrated a submerged overclocked system running without a heatsink at very good temps. A cookie goes to the first person to bulid a farm in a huge fish tank full of that liquid

Flourinert, I think. Good luck paying for it.

People have built computers submerged in oil before, you just can't cool anything too powerful. There's also a company (if they're still around) that sells high-end systems cooled with standard liquid loops, but the whole thing is submerged in oil for good measure.

holy crap 55 gallons of that stuff weighs 850 lbs! can you imagine the shipping cost on that?!?

I suppose if you have too much money, you can get one. Cost/benefit analysis would make it seem pretty clear that it's a huge waste of money, though.

Check out this sweet FOUR THOUSAND DOLLAR config:
1 x Overclocked Intel® Core™ i7 950 Quad Core Processor (3.5GHz, 8MB Cache)
1 x 650W power supply
6GB DDR3 1600MHz (3 x 2GB) tri-channel memory
1 x NVIDIA® GeForce® GTX 470 1280MB 320-bit GDDR5 video card
1 x 1.5TB removable hard drive
Slot-loading DVD burner
Microsoft Windows 7 Ultimate 64-bit

Wow. Blistering performance with only the latest parts...

I can't imagine the hassle with warranties. Also, I remember there being someone on either xtremesystems or silentpcreview that used a custom box and filled it with mineral oil to cool his components. He ran into issues of the oil eating his sealant on the box. It was interesting, but it just isn't practical.

[trn]

considering his tubing is a poop brown color i don't think the color of the coolant will matter too much lol

I concur... any color will be juuuust fine.

I think mineral oil (which can be bought by the gallon at hardware stores is electrically non-conductive enough to not short computers. I think you just disable or remove all fans and you can dunk your parts in a fish tank of mineral oil and use that for passive cooling.

Besides being a huge mess and not so easy to manage i'm not sure thats a good concept for a mass crunching farm. Even if I had a huge tank of this junk and I filled it with crunchers that constantly dump 3KwH into the tank... then how is the tank and liquid going to deal with that heat? This is extreme systems and people do all sorts of crazy things here, but for a crunching farm I think you need a way to move the heat away from the crunchers constantly. The easiest cooling solution is to move within the Artic Circle and crunch with air coolers Or heres a good idea... () No matter were on the globe your located, at ~30,000 feet its really ing cold! even at the equator. Uh... after a bit of FAA clearance you need to hoist your crunching farm about to about 30,000 feet with some weather balloons and a hell of a long extension cord and fiber optic cable. Solar panels will also be more efficent at those heights and winds can be very very strong and constant so you can supplment your power needs with solar and wind also! So who at XS wants to build the first upper-troposphere WCG farm??

[shoota]

Now we're starting to think down the right path!

[jcool]

TRN, you are running tab water in your loop right? As others have suggested, I would strongly recommend adding a real corrosion inhibitor to the mix (not PT nuke )
I use 1 part BASF G48 to 10 parts of destilled water in my watercooling loops. Works great even in mixed copper/alu loops (I have those for purely passive WC setups). No corrosion whatsoever even after several years of runtime.
Besides, it looks cool - turns your water into a light blue. You should be able to buy it at your local car dealer (since it's the same stuff that goes into cars) or order it online.
It also offers algae protection and anti-freeze capabilities - the perfect AIO solution really. For cars and PCs alike

What you want is the topmost bottle here:

The others work just as well, but being red, they turn your water into a really gay looking color

[Jaco]

anything is better than the poop color he has now I'd think

[OldChap]

aaah, .....Pink........Lovely

I think I may have over done it here My rad just showed up at the door...... it is about 2'9" wide and come to above my waist when standing on the floor

Still ......should cool 3 maybe 4 rigs ok ....maybe even run it passive what do you think?

Nice!

What's that bad-boy from? a lorry? My biggest rad was from a '91 Chevy Blazer and is 34" x 24" x 1.25" or so. I'm sure it could run some rig passively, if you add one very low speed fan then it would do even better.

[OldChap]

yep,



The hose connections are 2 1/2 inch so I have some parts still to buy to adapt it down to 3/4" Lord knows what the volume or filled weight will be

I'll try to get some pics later

Very nice! i'm jealous.

I tried to find a massive truck radiator here but they were all $700+ for a large copper truck radiator.

[OldChap]

haven't really had a good look yet but I think this is a mix of copper ally and plastic

re-cored and in a sale ~$80 delivered.... bit of a no brainer really. I have a bronze circulating pump (just needs cleaning) copper pipe some brass fittings and taps hoping to add just rubber and plastic tubes and auto anti-freeze. Something to do over Christmas if Santa brings me some blocks (ek hf)

[disturbed13]

hay trn
what are the temps on your farm
its going to be cold in florida this week
you are in florida................ right?

Very nice; I think one thing I've learned from is that the brass circulator pump is worth the extra $$ vs the cast iron. I hear the EK blocks are priced better than in the US. The car/truck/lorry radiators are such overkill in water cooling just about any block ought to do the trick; 2C or 3C probably won't make or break the farm's performance. Anything you can get your hands on with good flow ought to do nicely

46F right now and suppose to reach 32F tonight We had a cold winter one week last year and I hauled my ghetto-rigged WC w3520 outside at 4am one night to bench on my back patio at 32F to reach 4.5GHz I don't think i'll be repeating that experiment tonight The farm is enjoying the nice cold weather though, and i'm regretting moving the PC's outside

[shoota]

wow good work, 4200mhz, 100% load, mid 30's C. that's temp pr0n lol

[trn]

Temps might even drop below 32F in your neck of FL tonight, time to huddle around the crunchers for warmth

[ggdh]

Make the fans pull the cold air from outside

[EtaCarinae]

trn, your temps at 4.2 Ghz are oustanding. I will never be able to match that with air cooling. And we are having at the moment -2 Deg Celsius.
But frankly if you are at such low temps, and your motherboard is good enough, and the PSU can keep with load and voltages, and power consumption cost are ok for you, then push man, push those clocks up, move to 4.3..4.4...4.5.. The 980X is capable of that. If you have 5% more on one unit you have 64% of an equivalent additional unit if you push all your 14 rigs. That is another 30'000 points at least. But yes they are pretty expensive. These are golden points.

[EtaCarinae]

trn I thought your objective was 100'000 ppd. You have reached it and are now largely beyond. Yesterday you were approaching 150'000 ppd.
I will have difficulties competing. I plan some additional power but I wonder if I can keep that level.

[D_A]

Once the numbers of Sandys start growing I think we'll see some sudden jumps in people's numbers. I think the show will be quite entertaining to watch.

[shoota]

I suspect it'll be a sort of dual effect from SB. The number of high end 1366 & 1156 setups that will trickle down to the "little guys" (like me) will also boost the numbers effectively. Gotta love sb

[D_A]

Right now I still only have 3 64bit machines, two of which are Opteron duallies (170 and 185) the rest are 32bit (sossamans, still love 'em though). If I could somehow score a couple more Q6600s I'd be pretty darn happy, some i7 920's and I'd be somewhat over excited or some 2600s ... well I'd need a towel or three ... and all the kit to actually USE them.

Freak reporting day I think I was averaging about 110,000 when all my machines were up. I've been cheating a bit, running HCC exclusive which my Linux machines love. I had 3 or 4 machines go down a week or so ago, I've been away from home in China for a bit, they should get a restart in a few days. No way I can keep up with the solar system, and i'm not even trying to win that battle, i'd get sucked into a black hole. I'm content for now to just try and keep everything up and running in the low 100,000's

Speaking of being content, i'm also skipping the SB's for now. PPW isn't really any better than 6 core westmere with moderate clocks, my L5640's draw 185W and are producing average 6,800 ppd with windows and 7,600 Linux right now. I haven't been tracking the forums so much recently but I think that was out performing what Dave quoted his 200W SB at? 4 cores is soooo 2007 Intel you can do better than that!
