How to stop phase change from condensating?

post #1 of 18
Thread Starter 
Hey i was wondering what would be the best way to get the chilled water from my cooler to my processor? What would be the best type of hose to use for this and what would i have to do to keep the condensation away from my motherboard or any other components?

Much appreciatied, Matt

well you cant if i belive, you have to get a liguid that is non conductive that stops the condenstion from getting on the mobo.

OK sorry I usually try to restrain from being a, well you get it but please dont make a post on something like this when you dont know what the heck you are talking about. You spread info that is not even related to the question and hopefully noone is stupid or inexperienced enough to follow your suggestion.


Ok since your hoses carrying the water will be potentially below the point of condenstaion and therefore will create moisture/water drops/ whatever you wanna call it you need to proof them just like you would a tec/phaseunit.

Basically there are many ways to do this but from what I have scene you need to get some type of pipe tubing insulation. Usually home depot or similer is good now put this on your tubing running up to the cpu/gpu and seal it at its seem very good. Use whatever type of tape like black electrical tape that will stick to plastic/tygon tubing to seal the end that is away from the cpu.

Now for the head of the cpu you use the same type of setup that you would for a TEC. Look up some of the guides. Basically there are a couple of methods. For one you want to make a seal that prevents any air from getting in as this is what will bring moisture. The back of the mobo will need either a conformal coating of some kind coupled with a closed cell foam/ neoprene on the back behind the cpu. Now you dont have to do the spray or whatever on the back as long as you get a good seal. Usually what I do it get some dielectric grease and put that on the back then the foam over that then the backplate of the attachment for the cpu block. What this does is makes a airtight seal via the foam and the greese when it is compressed.

Now for the front side you will something similer, basically a foam/neoprene section cut out that sits around the cpu socket. Use the dielectric greese bewtween this and the mobo and press it down on there. Now the water bloack should have some kind of Foam or neoprene wrapped around it and sealed up to the hose covering insulation that you have on there. Make sure that these two are sealed together very well. Now your water bloack all wrapped up is pressed agains t the foam insulation on your mobo around the socket with a nice layer of greese between it. This forms a air tight seal when you tighten it down.

You will also want to put some dieelctric greese in the socket under the cpu to protect the cpu pin area from condensation and corrosion or pin rot as its called.

I kno9w we dont have many guides around here but if you need one I could try and take some pictures and show you how its done for the most part. I think there are some good guides at VR-Zone and XS in there extremem cooling section that will give you a good idea of how to get it done.

Good advice there.

Use close cell foam (like neoprene) to keep air from contacting anything below dewpoint. As pointed out there are many options to implement this barrier.

I found commonly available Vaselin is a great dielectric--you should slather the socket and surrounding area with this to make a vapor barrier to seal the foam to the mobo--easily removed with electrical cleaner

I heard Vaseline goes bad or starts to run over time. It is good for short term benching but is not recommended for long term setups... so I heard.

Hey Madmax22 would you mind posting some pics up so i can get a pretty good idea of how it should look. Thanks

Much Appreciated

It would be easier to not as I dont have your setup but I could do some thing to show you the basics. Let me know what your gonna be running like the block and stuff like that.

Read these guides, look in there for condensation proofing and the such
Link1
Link2
Link3

These are just a few places that you can find some good info on condensation proofing. Yes most of it applies to phase change and tec's so between the two you should get the idea of whats going on. Its all the same principle so make sure you use some common sense and like the measure twice cut once make sure you have a good seal or you will destroy some stuff. I have not borke anything from phase cooling but I have been relatively careful adn a little lucky.

ok i have a compressor cooling a 2'x1' bucket of water thats about 8 inches tall. Im just guestimating.. everything is outside except for my computer. Ill be using a block that me and my dad are going to custom make at his machine shop. We have access to tons of metals and some kind of thermal plastic he was talking about which he says would not condensate as much. I have another question. Does anything else need cooling or would the cpu be fine? (Im not going to cool my graphics card until i know the cpu cooling is 100% done)

Well coll what ever you want but the main three are the cpu/gpu/NB. I would definatly go with the cpu and strongly consider the gpu. The NB usually only benefits from this type of cooling when doing some extreme ocing like ln2 on the cpu or something like that.

The gpu could greatly benefit from it but thats up to you and how much you wanna deal with. You could allways add it later on and just do your learning on the cpu for now.

Try and read up as much as you can and Ill try and get a guide together for you this weekend (probably pretty makeshift but itll do).
As far as the block for the cpu a all copper one would be the best but experimenting is allways good also so have fun with it.
