water cooling

[Guest]

I am going to make a chamber that goes between a heat sync, and my golden orb. this chamber will hold 10 ml of water, will this help my colling problem or not?

This is an interesting concept. Will not have any flow or an effective way to cool the water? If so I dont think that it will work to good (although I have not tried that) but most water cooler units use a small radiator to cool the water. If you try it and it helps let us know.

well, water is probably (don't have any numbers, but this is an educated guess) a better thermal transfer compound than any grease based stuff, even arctic silver. But it's not as good as metal, so to optimize energy transfer as well as minizing risk of a spill, put as little water between the cpu and HS as you can. All you need the water for is to transfer energy to the HS so it can radiate it away. Also, make sure the seal is good. At 50C water has a not-insignificant partial pressure and will want to give off a little steam, so whatever you use to seal the chamber make sure it can take a little heat and pressure.

from what i understand, most water coolers pump the water to a larger radiator to dissipate heat; without a pump the water is only good for moving energy to the actual HS.

I was planning on makeing it out of copper, putting it together with JV weld or something, the thing that makes it messed up is that my chip is a slot 1, or 370 in a slot format. I may hold off until i get my celeron (socket) up and running.
I can use all the input i can get so Thanks.

I wouldn't recommend that water reservior idea. It will have an adverse effect on cooling. In a normal water cooling setup the hot water is removed from the CPU area and given time to cool before it is pumped back. That's why it is effective.

You need to move the heat away from The CPU. And, in your setup, only the golden orb does that, so the water will only impede the heat transfer to the orb. The Thermal conductivity function is:

(thermal conductivity of the material)*(cross-sectioal area)/(length)

So by increasing the distance the heat has to travel to get to the orb and decreasing the thermal conductivity of the material (water conducts heat worse than metal), you will decrease the conduction of heat.

The only benifit that I can see is that the temperature change will be leveled out some. When going from idle to full load it will take longer to reach peak temperature, and vice versa.

I enjoy reading ideas like this. It's nice to know that there are people out there like me who can never leave 'good enough' alone. Keep the ideas flowing.

it's funny you mentioned that because I had the same thought. As the machine sits now it has an orb (for slot 1) a hood from the power supply(a gateway cooling soulition) and a 40mm fan that when it fires up It sounds like a air conditioner, I have room for a water colling unit yet I think the cost is a bit excessive.

You could make your own water cooler. The hardest thing is the water jacket,but you can buy one for $20. Other than that you would need a fountain pump, a reservior (a plastic underground electrical connection box works well), a radiator (heater core from a car is perfect), and some rubber tubing and hose clamps.

if you really want to cool that rig see my idol

the fool, or the fool that takes his advice?

Thats the coolest rig I ever saw.

I made a water cooler using a car transmission cooler. It really wasn't that hard or expensive. I doubt the water transfer idea you mentionned will be that effective without water flow.

I'm just curious...
Are there any adverse effects resulting from submerging the top side of a Socket A Athlon? (or any other FCPGA chip)
(i.e. with a five-sided rectangular container epoxied onto the Athlon, with water circulation to a radiator)
