Question about condensation???

[Amd Man]

Just wonderin, do you think that an 80w peltier will chill my water enough to cause condensation, I am thinkin of just building a small 80w peltier chiller. Just to help bring down the water temps alittle. I am either going to use two blocks and clamp togetherwith pelt in the middle and use a fan to cool the hot side and let the cold side chill the water. or just use two HS and clamp them together with peltier in the middle and submerge the coldside heatsink into the resvouir and let the hot side be cooled by my MC462(SwiftTech)

AMD,

I dont think you will have to worry about it, because I dont think the 80w peltier will have much of an effect on the water temperature at all.

Heya AMD,
just curious, what happend to the mini fridge? If you stuck your radiator/s in it, it seems like that would be a lot more effective than a peltier chiller...

[Amd Man]

Well I still have it and I could still use it, it's still just sittin in the box, I just don't really want to drill holes in it for the water lines and then I have to insulate the whole waterblock and lines and then I have would have to leave the pump and fridge on all the time to keep the water from freezing. It's still an option I just have to stop thinkin and start doin:)

Just cant decide on a setup...

hi AMD Man, i'm v.interested in what you do as i'm toying with the idea of a waterchiller myself, ive an anodised pump/res that i'm thinking of peltiering up anyone have any suggestions ? i'm against noise so no monster fans :D

[Player0]

The only effective way to waterchill with peltiers is a dual loop system with at least 300w of peltier power.

Sure, you can cool a resevoir, but you cant have radiators on the same lines as the cooled water, or the radiators do an excellent job of warming the water right back up again. That means you have to fully rely on the peltiers to remove the heat from the CPU. If the CPU is running 100watts, you need 200w of peltier to adequately cool it. But because of water cooling innefficiency, you really need 300w of peltier to do the same task.

And of course, you cant air cool the hotside of 300w worth of peltier...so you need a second water cooling loop just for that task. And you have a dual loop chiller.

I've fit dual loop chillers in to standard size full tower cases. If you do the resevoir itself, you might even beable to fit it in to a midtower, but it would be tight. On a budget, you could do a simple dual loop for $300-$400. You can buy a freon based water chiller for about that, if you dont mind the bulk.

The other solution is to directly mount a 226w peltier to the cpu and use the standard water cooling system. this works okay...ask NY...hes doing that.

Go to the above link to see what the guy did with air chilling, looks kinda neat, but I would take the same set up and pull the fan off the cold heatsink and submerge the heatsink into the resivour, and let the pelt cool the water that way...A 80w pelt should be able to cool water...

[Player0]

Ive done air chilling as well, it made very little difference on my old Tbird 800.

The 80w peltier will cool the water a little. And the radiator will cancel out the effect.

[speculative]

Really? A radiator would cancel out the effects of a Pelt? Why is that? :confused:

-spec

[Player0]

Well, any benefitial effect. If the pelt was able to cool the water below ambient, the radiator would just raise it back up. The average radiator is about 10x-20x more powerful than the 80w peltier.

[speculative]

So the radiator generates heat? Or are you saying that if you have a mass of metal that's room temp and you cool the water below ambient then that mass would heat up the water somewhat negating the effect of the pelt because the rad is @ ambient?

-spec

[Player0]

Yes...the second one. The radiator does generate heat as well due to friction but thats a different discussion hehe.

The radiator tries to keep the water temperature at Ambient. If the water is above ambient, it cools the water. If the water is below ambient, it heats the water.

So, if you want below ambient water temperatures, the radiator will do nothing more than get in the way in a single waterloop system.

If you only want closer to ambient water temperatures, yes pelt cooling the water will help to reduce temperatures. However, adding a second radiator is a much more efficient and cost effective way to do this. Again, 10x-20x the cooling power of an 80w pelt

Ps - dig the super mario review :)

[speculative]

Cool; that makes sense. :)

There's some pretty cool modding going on in the gaming community it appears. Check out this LCD mod for example:

http://www.ninjamicros.com/vbulletin/showthread.php3?s=&threadid=12237 They even got an RGB signal out of it! (That first pic shows the output simultaneously on a TV and monitor.)

Glad you liked the review - I'm gonna try to intersperse reviews of newer games with some of the classics.

if determination forces you to use it.. i would reccomend attempting to cool incoming h20 before it hits the processor h20 block.. as then any cooling it may actually do would be absorbed by the processor...
would it work? or rather how much would it help?
curious to see.

[Amd Man]

So you would go pump-radiator-chiller block-resviour-waterblock-pump.. I think that would work, then all of the chilled water would store in the resviour.....

[tripodal]

the order i meant to imply would put the pelt chiller directly prior to the cpu waterblock


my order would be
pump radiator chiller waterblock resivoir

at least then any cooling added by the pelt would be used by the cpu, it is highly unlikely that the pelt will affect the temperatur of the system as a whole .. perhaps 1C at the most... but you may see a better gain than that between the chiller and cpu, which is where you want it to be anyways
