not sure if this has been done yet

post #1 of 7
Thread Starter 
ok, well just to let you know, ive never done water cooling, nor have i ever really read up on it. but one of my friends at work had (what i thought) a really cool idea for water cooling, SO i drew out a picture of what i could remember about it and thought i would ask you guys if its feasible or not.



hope all that makes sense, good ol' ms paint

basically, what he wants to do is put aluminum or copper hs's in a reservoir and have peltier units attached to the bottom, thus making the hs's cold, and have the coolant flow over the hs's and making the coolant even colder than the radiator could.

What would you be cooling the peltiers with?

Just put a peltier block between the waterblock and the CPU. That is a proven method.

if those are phase units (say, out of an air conditioner), then you wouldnt need the radiator, as it would actually raise the water temp.
What you are referring to is usually called chilled water cooling.

If the water temperature gets below ambient temperature, (which looks like what you are going for) then you will need to insulate the tubes and the blocks to make sure condensation doesn't get anywhere.

There are a number of articles on the subject, and it is an effective way of cooling more than one block to sub ambient, but a lot of protective measures have to be made on the tubes, the coolant, and usually the pump as well.

ok, so basically if it gets colder than the temperature inside the case, it will cause condesation, is that correct?
and if you dont want that to happen, you would need to insulate the tubes and take other precautions. ok, that makes sense i suppose. but anyway, thanks for the input guys, i just wanted to see if his idea was original or not, but i'm not surprised it isn't lol.

Thats why we use dialectric grease around the cpu area with a strong pelt or phase unit. To offset the condensation.

You might want to look at the CoolIT Freezone. They are pretty decent (a bit pricey mind you). They combine water cooling with a TEC in a single intgrated unit. They have just released a model that allows you to add gpu blocks as well.

The reviews i read on the freezones were wishy washy- the tubing is small and the tec is a relatively low power one. Most agreed a good water kit would do you better (which i recommend). You wont get sub ambient temps, but theres also no condensation to worry about, and no tecs to power or cool the other side of.

If youre set on sub ambient, a few water companies make tecs built into a waterblock, keeps the condensation issues to the cpu area only, and has the added benefit of already being prepared for a water setup.
