Case fans with heatsinks attached

Huntsman, its called a slush box , and if you know what your doing you could get negative temps for about $75.

I am totally willing to help you if you want to achieve these temps.

Its a version of a phase change that is LOADS easier and very cheap. its just difficult to insulate the tubing at those temps.

 
err I can see this working if it was like this

0 = fan

* = heat sink

C = cpu

| and _ and - is the case


|-------------------------------------|
|0*0*0*0*C*0*0*0*0*0*0*0|
|<---<---<---Airflow<---<---<---|


and this thing is a huge wind tunnel of doom with a tower CPU cooler, and the fans would be big and quiet! and obviously use as many fans and heat sinks it takes to go from one end of the case to the other
 
now that would be a lot of work and alot of money for quiet fans, i think. But i would try the slush box, but a radiator looking one sure seems like a good idea just not sure where i would keep the box and pump would it be inside the case or outside ?

My main every day use rig. Will add gaming rig too.

now the pipes would have to me soldered to the heat sink right ? or can the heat sink be mounted and then run the pipes through it? Because i think it be easier to cut the holes out and just make a heat sink and then put pipes in it and just connect them all instead of soldering the pipe to each fin.

and how loud would the pump be?

 
it would be infront of my case as i took the grill off because it makes it alot louder with them on. So i got room in front and i would put the heat sink there so when the fan sucks in it goes tthru that heatsink first and then cold air into the inside of the case.
 
A slush box uses a refridegerant to cool a liquid to well below zero.

I know how to make a real cheap one. But you will still need a pump and tubeing etc.

And when you deal with refridgetrants yopu cant just "solder" stuff together, you have to braze it. Braze will hold LOADS more pressure.

It is super simple to make a slush box.

The cheap way to do it is:

Buy an a/c unit from craigs list for $50 then take off the top of it and bend the evaporator so it will fit in a cooler. Put it in the cooler then fill the cooler up with an anti-freeze (or something witha low freezing point). THen put the pump in the cooler with the super cooled liquid and watchj your temps drop.

You usually DONT need a radiator for this kind of cooling.
 
i mean like a radiator looking thing. With pipes going thru it to cool it off, But how would you make it? If it was up to u i wanna make something like in the drawing i made so how would you do that ?
 
Believe it or not i am working on somthing like this right now.

A couple of the guys on toms are awaiting its arival. I am using the evaporator from an ac unit. it pretty much looks like a car grill with 20 pipes going through it. It is the exact same thing you drew in that drawing.


Here are my designs....

This is a picture of what the whole thing looks like, the liquid in it will be freon that is under pressure so i can raise the boiling point to 30c.

each heatpipe would be about a foot long so they can be attached to the grill.

The copper block would be made out of copper end caps. If you have never seeen them they look like this, and are about 2 inches around.

Here is my design for the block...

I was going to have a TEC cooler between the cpu and the copper block so i can possibly reach negative temperatures on only an air cooler.

Please excuse my paint skills ^^ im not very good.

 
dont worry bout the paint skill but ur doing it for a cpu while i just want to do it in front of the fans, ima put more thought into it and see what i come up with. and looking forward to seeing how urs works out. When you done put up some pics.
