So I just had a thought

post #1 of 7
Thread Starter 
Wouldn't it theoritically be possible to throw salt in a waterloop and throw it in a subzero environment and subzero cool it since the freezing point would drop.
I know it would corrode anything that is a ferrous metal so wouldn't you also have to have non-ferrous fittings? and could it potentially clog the loop even if you stayed below the maximum capacity of what can be dissolved in the water by weight?

Ethylene glycol (anti-freeze) does the same thing as salt when mixed with water, lowers the freezing point. Salt water not only corrodes/promotes rust in ferric couplings, but also non-ferrous metals like aluminum. Better off to avoid it entirely.

If you're thinking of how home made ice cream makers lower the temperature of ice by mixing with rock salt, the action at work is that the salt melts the ice and lowers the freezing point of water at the same time. When ice melts, heat is absorbed, lowering the temperature of the ice water - and the salt lowering the freezing point means the ice water is below 32 degrees F.

You'd spend SO much energy keeping the temperature down though. So much it probably wouldn't be worth it. As far as I know in classic water cooling what cools the water are fans and radiators. You would need much more than that to get the water to under 0°C. Unless you live in Russia or something; but then you might as well just open the window.

Salt would be a pretty bad choice since it would turn your coolant into a vigorous electrolyte, which would accelerate galvanic activity across the board. All metals, not just iron, are affected by that. I also imagine higher salinity would harm other non-metallic materials in a common loop such as acrylic and vinyl.

But what you're considering has been discussed in other threads quite a lot so I'm sure a little searching will turn up a lot of useful info. Most of the time people talk about mixing in anti-freeze.

I'm not sure though if you're talking about putting a computer outside in sub-zero temps, or using active cooling such as a peltier etc? Under what scenario do you envision your coolant needing to be below 32?

The thought actually originated when a friend sent me a text with a picture of one of his cores at 9C because of the location of the room its in in his house and I had the thought of throwing my loop outside and responding but then realized it would freeze and then salt water came to mind.
I've seen what it does to ferrous metals and that's why i mentioned that but couldn't somebody in theory just use copper fittings and an all copper rad to eliminate. or for example people that do the full copper loops with copper piping and everything?
I realize antifreeze would be better and honestly didn't even think about it, but couldn't you just throw it on a screened porch/deck and be done with it?

This is all just a thought I was curious about and had no intention of doing it.

Rubbing or even surgical alcohol can be used due to its way way way lower freezing point, though it has a lower boiling point at your temps you'll not have to worry in that area. The only problem is that alcohol is will react to aluminum and acrylic and possibly other parts. Not sure what ratio can work to stretch out the corrosion but yet have the lower freezing point. As mentioned earlier anti-freeze would be your best option.

Edit: Note antifreeze is toxic and some countries have laws on disposal.
