I'm past thinking about water-cooling (5, Insightful)

stecoop (759508) | more than 9 years ago | (#10622420)

I once thought peltiers would be great with water cooling but we read on /. the other day [slashdot.org] that these devices are 5% efficient so that's a no.

Water-cooling has a few kinks like electricity near water and corrosion - at least a few years ago that may be solved no days with Antifreeze but you still are at the mercy of the ambient room temperature. It's finicky enough that you couldn't build a machine with water cooling and leave it in a room for 3 years so that leaves a hole in reliability as I couldn't leave my machines on while going away for two weeks on vacation unless I didn't mind rolling the dice to seeing fire trucks at my home.

Considering Water-cooling Your PC? This was the leader I was until I saw a home made [burnoutpc.com] active cooling system. I first saw active cooling systems from http://www.vapochill.com/ (website down?) and have been waiting for someone to take an AC compressor and attach it to a computer case. It seems that were just on the verge of DIYers of achieving satisfactory results in active cooling systems; therefore, I will hang on to old reliable (the passive radiators) until I can muscle up the nerve to go the active cooling route.

Water cooling is stable; as long as you make sure you have no leaks as you assemble.

deacon (40533) | more than 9 years ago | (#10622761)

The Peltiers we tested in the lab needed the same amount of electrical power as the amount of heat they moved..So much better than 5 %, but it doubles the thermal load on your heatsink.

BeerCat (685972) | more than 9 years ago | (#10622422)

OK, so water is cheap, but why not go for materials with better cooling properties (like in a fridge), which would be more efficient?

Something that is non-destructive to PCBs if it leaks would also be a bonus.

Re:Why water? (3, Insightful)

Anonymous Coward | more than 9 years ago | (#10622489)

If you used a fridge there would obviously be major problems with condenstation. I guess the main selling points of water cooling is that it's better than air and it's not as expensive as something like VapoChill. . .Plus it looks damn cool with some UV die :)

I took care of the condensation problem the easy way. I can have it as cold as I want without a problem. The fix: Live in the Desert! It's rained once since I've moved here, and the air filter in my case means dust isn't much of an issue.

Water has excellent heat transfer properties, (better than the refrigrants in your fridge), is easy to handle, unlike some of the better heat transfer fluids such as liquid metals, and is non toxic.

If you want to immerse your computer, Flourinert has been around forever, though now probably banned.

Re:Why water? (2, Insightful)

Ironsides (739422) | more than 9 years ago | (#10622510)

Refridgerators use a heat pump which has an efficiency of about 5%. Thats not acceptable for cooling processors which output 100W. You would need a power supply specifically for your cooler.

deacon (40533) | more than 9 years ago | (#10622838)

[Enigeering detail ommited to pass lamenes filter]

The EER rating on air conditioners (a common heat pump) tell you the ratio of heat moved to power expended to move it. The units of EER are messed up though, it is BTU/HOUR divided by Watts, multiplied by some factor of 10.

Water is a much better coolant than your typical refrigerant. The reason water is not used, however, is because its boiling point is far too high.

watercooling (5, Insightful)

Large Bogon Collider (815523) | more than 9 years ago | (#10622430)

The major hangup I have about watercooling systems is fault tolerance. How the the whole system handle 1) pump failure, 2) water leak, 3) coolant loss, etc without destroying the PC, or worse, starting a fire.

Re:watercooling (2, Insightful)

The Asmodeus (18881) | more than 9 years ago | (#10622540)

How is this different than a heat sink + fan? If the fan gives out, you're toast.

Re:watercooling (5, Insightful)

Large Bogon Collider (815523) | more than 9 years ago | (#10622667)

Semi-true. In many newer processors, if the fan gives out, the CPU on-die heat sensor throttles back power consumption to prevent overheating. However, with a HS+fan, there is only one point of failure, the fan. With watercooling (which I have thought long and hard about), the fan can fail, the tubes can crack/leak/break, the connectors and fail, the pump can fail, corrosion can block the waterblock, etc. These are not just hypothetical situation - they have happened. The scariest part is if the water leaks and shorts out something expensive - esp. the CPU and graphics card (which is usually sitting directly below the CPU). I would be upset if the cooling system caused a fire, but would be even more so if insurance decided not to cover it because of my modifications.

Re:watercooling (5, Informative)

The Asmodeus (18881) | more than 9 years ago | (#10622901)

Corrosion should not happen. Not in the lifetime of your system anyways. Distilled water + anti-corrosion type additive should see to that in closed loop system.

These systems must have UL approval right? If so, I don't think your insurance company would be able to say jack if you didn't just grossly mis-install it. But, since it involves water + electronics, I wonder about requirements of a GFCI circuit.

Re:watercooling (2, Insightful)

Minwee (522556) | more than 9 years ago | (#10622611)

The same way your air cooled system handles fault tolerance -- The onboard hardware monitor detects a high CPU or motherboard temperature and shuts it down.

After looking at how CPUs handle faulty heat sinks [tomshardware.com], you would think that having a large supply of water nearby would be a good thing.

Re:watercooling (1, Informative)

Anonymous Coward | more than 9 years ago | (#10622646)

I suspect, it would be better then if you had a fan failure. Remember that unless its underpresser water won't heat beyond 212F unless you put enough energy in to vaporize. It also becomes pretty vicus as it becomes warm, so convection will cause it to circulate to some degree, as will very slow boil where its not so fast that a layer of vapor separates the water from its contact with the cpu. So basicly very worst case senerio your cpu hits 212F, water has a very high specific heat, so if you have a decent sized radiator and a resonably large fluid volume, I would be really suprised if it got hotter then that.

Re:watercooling (2, Interesting)

Greyfox (87712) | more than 9 years ago | (#10622651)

Why not use heat pipes to duct the heat into a passive resivoir? Sure, it might take some work to get the heat pipes bent the way you want 'em to fit in the case, but once that's out of the way it should be pretty smooth sailing. You won't have to worry about moving parts breaking, and you won't have to have running water in close proximity to your electronic components.

Re:watercooling (-1, Redundant)

Anonymous Coward | more than 9 years ago | (#10622698)

Redundant. Put two pumps in series and if one fails it will still pass water while the other keeps things running.

Re:watercooling (2, Funny)

Zangief (461457) | more than 9 years ago | (#10622754)

If you are running BeOS, you can program fault tolerance into software, through intellligent use of the system calls "isComputerOn" and "isComputerOnFire". The first returns 1 if the computer is on, undetermined if not. isComputerOnFire returns 0 if the computer is not on fire, or the motherboard temperature if not.

You would probably be better off..

the heat transfer equation H=h*a*(delta T)

H=heat

h=heat transfer coefficient

a=surface area available for cooling

delta T=diff between temperature of device to be cooled and surrounding cooling fluid

shows that the easiest way to cool something is to reduce the temperature of the fluid that cools it..

If you lower the air temp in your computer case by 10c, the processer temp drops by 10c, assuming the fans all stay at the same speed.

Increasing "a" is limited by fin efficiency (which is what these water cooling systems are trying to get around, but a sealed evaporator/condenser would be smaller and more efficient, there is a metric buttload of patents now on sealed passive boilers/condensers), and as air speed increases, "h" rises less and less in proportion)

If you want more info, look at the free download of the heat transfer textbook I list in my journal.

AgentSmit (764269) | more than 9 years ago | (#10622822)

All those fans to keep everything cool are quite annoying, especially in those quiet movie parts or long work sessions! So why not get rid of them for that reason instead of temperature?

Cheap? Cheerful? How about WORKS? (3, Insightful)

Anonymous Coward | more than 9 years ago | (#10622495)

Damn, if I'm going to pipe water through my PC, I want it to be reliable and effective. That's it.

Who the hell cares if it's neon?

Re:Cheap? Cheerful? How about WORKS? (2, Insightful)

Artifakt (700173) | more than 9 years ago | (#10622919)

The original points of this were:
it's easier to trace small leaks with neon or florescent dyes in use. Use opaque hose, and bring an actual black light near it, and you have one of the world's best cheap tests for system integrity.
Stock antifreeze is florescent green anyway, and it prevents some kinds of corrosion, so why not use it.
Now the case modders are going for the whole hobby effect, with transparent case windows to show off the glowing water inside, and built in UV sources to heat up that case they are trying to cool down (and even cold cathode lights produce some heat), so they are worrying more about apperance than substance. It's the geek equivalent of oversized exaust extensions on a rice burner. But originally, this was about being reliable and effective.

What About? (4, Interesting)

seaniqua (796818) | more than 9 years ago | (#10622506)

skipping the pump and hooking directly into a low-flow water line? This would be the most expensive option (water bill), but eliminates the possibility of pump failure, and isn't reliable on ambient roomj temp (my water is quite cold when it comes out of the faucet, regardless of how hot the house is). Of course, if a hose leaks, a self-contained system would stop dripping when the reservoir was empty, while this would flood the whole house! Anyway, something to think about

Enigma_Man (756516) | more than 9 years ago | (#10622842)

We actually heated / cooled our apartment at school like this. We had a Saab radiator I scavenged hooked up to the kitchen sink. We rigged up some cardboard ducting, and strapped a few fans in pusher-configuration behind the radiator blowing outwards. The hot water flowed from the bottom of the radiator to the top, so it remained in the radiator for longer, to throw off as much heat as possible. The water going in was hot hot hot, the water coming out was lukewarm (we'd run it at a trickle to extract as much heat from the water as possible). If we cranked it, we could get the entire apartment up to a balmy 75 degrees. It also worked "ok" to cool the house when it was hot, but much less well than heating the house.

kochsr (144988) | more than 9 years ago | (#10622511)

It was fun, i only had one leak (that was my own fault) but it was expensive. These systems are not for real world computing. They are for hobbyists that want something to do. I chose to do mine semi-homebrew style. I fabricated some stuff myself, and bought the other parts.

The only reason i did it was that it was nearly silent. Of course, you can do that with conventional cooling nowadays.

Why use Water?!? (5, Interesting)

Zarniwoop_Editor (791568) | more than 9 years ago | (#10622519)

Why not use something like the 3M product.

I saw a color tv floating in a tank of this at a trade show years ago, something about a running color tv floating in liquid is just wrong.

But I'm sure It would be much better than water for many many reason.

"Fluorinert FC-77, a specialty fluid from 3M, to cool the laser tube. It is a colorless, odorless liquid (just like water) and if you get some of it on your fingers, it is harmless, just wash your hands with clean water (according to 3M).

Here is the description from 3M web site:

"Heat Transfer Fluids
The wide liquid range of Fluorinert liquid FC-77 (-110C to 97C) makes it ideal for use in automated test equipment (ATE) and other semiconductor process equipment. Its high dielectric strength means it will not damage electronic equipment or semiconductor wafers, chips or packages in the event of a leak or other failure. In addition, FC-77 liquid is chemically stable, nonflammable and practically non-toxic".

Enigma_Man (756516) | more than 9 years ago | (#10622702)

Wowie! That'd be awesome.

You could have the "hot" areas of your mobo/videocard just totally immersed in this liquid. Throw in an electric fan to swirl around the liquid, and just strap a gigantic heatsink onto the side of the tank... nearly passive excellent cooling.

I saw on a website onetime where a guy had his whole computer in (IRC) mineral sprits. In the web site he recommened the use of FC-77 as mineral spritis is flameable; but the site noted that FC-77 price was quite high. A quick google search [parallax-tech.com] reveles that one site has FC-77 for a little over $200 a litter. Maybe buying a window AC unit and hacking it into computer case may be cheaper?

Re:Why use Water?!? (1)

Enigma_Man (756516) | more than 9 years ago | (#10622812)

Aah, I didn't realize it was so expensive... What about using this stuff as the coupling agent between the on-chip CPU die, and the heatsink/waterblock itself? Rather than thermal-goo, which doesn't have a wonderful thermal transfer coefficient, a liquid has excellent thermal transfer capabilities. I remember seeing a test on one of those hardware sites where they tested the abilities of different substances. I believed they tested regular thermal-goo, "arctic silver" with the metallic paste, ripoff arctic silver, peanutbutter and water. Water was by far the best, but has the obvious downsides of being well, ya know.

With this $240/liter stuff, you could use a sealing o-ring of some sort around the die part of the CPU, and put a drop or two of this onto the die, then put the heatsink onto the top of the whole thing, so you'd get an excellent thermal transfer... Hmmm... this is sounding pretty great.

I have some experience [polynomial.org] with watercooling. With proper care, it's safe and a quiet way to cool your machine. For those of you who move your computers around though, becareful what materials you use. I built my computer in a warm dorm room which meant that my copper block to plastic piping worked fine. Then I took it home to my freezing basement and water went everywhere. I think the metal shrank while the plastic didn't, and water came out of the connections.

Other than that I never had any problems. I don't use it anymore because it's too heavy to carry around all of the time.

Lq metal like NaK [wikipedia.org] are much more efficient [coolingzone.com] then water. In combination with a MHD pumps, the whole system can be free of moving parts and noiseless.

Re:Liquid metal (3, Informative)

HBI (604924) | more than 9 years ago | (#10622662)

From the second page you listed:

The best candidate seems to be an eutectic solution of sodium and potassium, (NaK). The melting point is as low as -12 C. Its density and viscosity are similar to water but it has a lower specific heat and a much higher thermal conductivity. NaK can be used with nickel, chrome and steel but it is aggressive to cadmium, antimony, bismuth, copper, lead, silicon, tin, and magnesium. It also reacts violently with air and water. It is apparent that this alloy is associated with several material and handling problems. Liquid sodium has nevertheless been used as a coolant for nuclear reactors, which shows that these drawbacks can be managed.

Sure, but do we want to manage flammable liquids that combust when exposed to air in our home? Pumped through our computer? Not to mention that it eats away at silicon and most likely the PCB itself.

I can see why no one considers this. ;-)

Re:Liquid metal (1)

deacon (40533) | more than 9 years ago | (#10622723)

I realize you are just joking, but for those who might think you are serious, a liquid metal system has to operate at temperatures that melt the metal.

So while great for nuclear reactors, the minimum operating temp would already destroy anything in the PC..

The only common item that uses metal cooling is hollow stemmed engine exhaust valves, which have sodium metal sealed inside. As the valve moves, the sodium splashes back and forth, moving heat from the head to the stem on the valve.

AlaskanUnderachiever (561294) | more than 9 years ago | (#10622845)

There are a LOT of major problems with metal cooling.

First of all unless you're using some seriously exotic components it's going to be solid at the temps you'd deal with in an average compouter (15-75c).

Secondly the materials needed to contain your liquid metal aren't cheap.

Thirdly it makes inspection for any potential flaws a real pain in the ass.

Fourthly you have to consider the viscosity of liquid metals vs. water or other coolants. The amount of energy you have to use to move them is going to be substantially higher.

Fifthly, the conductivity of most liquid metals vs. water (even water with electrolytes) means that most leaks are going to = dead computer.

Oh yeah. . .also. . .I totally forgot about toxicity issues, reactivity (sodium and potassium as you've selected would be really fun to have leak out of your computer and hit, say, a patch of wet floor). . .

Ob AVForums discussion... (4, Funny)

GillBates0 (664202) | more than 9 years ago | (#10622578)

An old (2002) thread from AVForums [avforums.com] about this guy who took "watercooling" a little too literally. Turns out it was tongue in cheek, but the whole thread is hilarious.

I decided this weekend to try and quiten my PC by following some other members lead and going down the water cooling road. The fans on my PC were really starting to drive me mad

The first thing that I did was to remove all the fans. The one on the processor and graphics card were no problem but the one in the power unit was a bugger to get out.

The most difficult part was sealing all the ventilitation openings in the PC case with silicon. I also put silicon all around the joints on the PC case. The smell of silicon was dreadful but when my wife complained I told her to be patent as it will be worth it when we have a completely silent PC.

Because I had completely sealed the PC case the only opening near top was the DVD drive. So I opened that and put the small hose I had purchased specially for the job into the DVD drive as far as it would go. With what I can only describe as great excitement and anticipation, I turned on the water. It really is amazing just how long it took before the case was complete full, and boy was it heavy. That didn't really bother me as I didn't intend to be moving the PC anyway.

Read on...

new way of water cooling? (4, Interesting)

LiquidMind (150126) | more than 9 years ago | (#10622628)

A few months ago, i saw this clip which had some folks at Good Morning America showing off a liquid that doesn't get things wet. they had a tank of this stuff and put some (powered) electronics in them (laptop, LCD TV) and they operated just fine underwater. They put a book in this stuff and none of the pages got wet as they pulled it out. Check it out [go.com]

anyway, it would be cool to find out if you can just put your whole computer in this stuff. cooling problem solved, right?

This isn't something to encourage. (4, Insightful)

pclminion (145572) | more than 9 years ago | (#10622663)

Water cooling, I think, isn't something we should be encouraging. It's just one more excuse for chip makers to ignore their chips' power requirements. The real solution is for the chips to run cooler, not to slap bigger and more complicated cooling systems on them.

If you're using water cooling for noise-reduction purposes, okay. But if you literally need it in order to keep your chip cool, there's something very wrong.

We should NOT be encouraging chip makers to continue avoiding power problems. It's environmentally irresponsible.

Be careful (5, Informative)

Pan T. Hose (707794) | more than 9 years ago | (#10622681)

Last time I tried water cooling my computer, the pipe started leaking, there was a short circuit and I accidentally set my computer on fire, which needless to say was neither cooling nor cool... After that accident I gave up altogether and do you know what I did? Instead of overclocking my CPUs, I started to underclock them. I noticed that in many cases even a 15-20% lower c;ock speed may eliminate the need of having any fan at all, as long as there is a large radiator with good contact and a reasonable air flow in the case. Sacrificing those few percents of megahertzes might sound very "not elite" but guess what? It still can display websites faster than I can read.

no, but I'm freezing my laptop cooling tray. (4, Funny)

cabazorro (601004) | more than 9 years ago | (#10622686)

I'm considering to put the cooling aluminum laptop
tray in the freezer overnight so I can get at least
30 min of work in the morining in my damn HP Pavillion ze4042 without the damn thing turning on the cpu fan that makes more
noise than my neighboors leaf-blower.
The laptop cooling trays are worthless.

How To Water-cool Yourself (1)

OccidentalSlashy (809265) | more than 9 years ago | (#10622721)

1. Run a cool bath. 2. Strip, submerge. Make self depreciating Microsoft jokes now. 3. Make sure your hair gets wet. And not just a little! 4. Soap. Come on! 5. Towel off completely. 6. OK, get dressed! Mom made you cinnamon toast!

Are we done watercooling yet? (4, Insightful)

karlandtanya (601084) | more than 9 years ago | (#10622738)

Reminds me of a 16 year old that bolts the entire Summit Racing catalog onto his mustang and thinks now he's a gearhead.


Go invent something. Go build something. Heck, even go break something while learning about it. Join you local tesla coil or ham radio club and learn something. Contribute a patch to an open-source project. build a watercooling system out of parts from Lowe's. Be proud of that.


Go buy something? Something that's largely non-functional, and unreliable? And bolt it on to your computer? Oh, yeah! You da man!

Isnt water bad for electrical components. (1)

tfcdesign (667499) | more than 9 years ago | (#10622744)

Ihope if you use water, you put it in somekind of container. It could ruin your computer. I bought an iBreeze for my iBook (exteranl fans) but I guess I could have just got a hotwoater back (like for the back) and filled it with ice water and put the iBook on top of it. I know of a guy who runs water from his fish tank through his computer.

Yea right. (1)

Kenja (541830) | more than 9 years ago | (#10622757)

Water in your computer! What could go wrong?

Sorry, but the 10% or so you get from over clocking isn't worth it.

Re:Yea right. (0)

I don't think you have any idea whay your talking about.

By watercooling my Athlon XP-Mobile 2600, (a $90 chip) I am able run 100% stable 24/7 @ 2.8GHz. That is a full 600MHz faster than the fastest barton available, and a full 800MHz faster than the chip is specified.

State of the art CPU cooling (4, Interesting)

freelunch (258011) | more than 9 years ago | (#10622807)

The Cray X1 employs Phase Change cooling in one of the more extreme power densities publicly known.

Check it out in this [cray.com] video.

Cray's phase change uses Fluorinert, while the average PC uses Freon.

I went with an XP-90 [thermalright.com] to air cool my new Athlon 64. The heatpipes arguably make it passive phase change cooling.

Load Testing Service (3, Funny)

rts008 (812749) | more than 9 years ago | (#10622814)

To the admin. of /. Have you thought of turning the power of /.'s smoking servers into an additional income source? I mean, you could offer to "Load Test" some outfits new servers for a fee and then just post a link on /. announcing something like: free beer and women who love geeks-click here. If their servers could take that, then they could be assured that their servers could stand up to anything short of a direct hit from nukular WMD's!

Air conditioning in computer room instead (3, Interesting)

BestNicksRTaken (582194) | more than 9 years ago | (#10622825)

Water can only cool to the ambient temperature of the room, and not below as some people seem to think - which is why it is no better than air/fan solutions, except for lower noise.

You'd be better off cooling your room with AC, and getting the benefit of cooling yourself, not just your processor!
