Water cooling liquids

[wun911]

If it takes x amout of heat to raise the temp of the "pure" water by 1 deg.

What can we add to water to make it now takes twice the amout of heat to raise the temp of the water by 1 deg?

Would it not be nice to have an additive in water cooling... whereby the water now requires tons and tons of heat to raise its temp by 1 deg???

I think this might have been discussed before, try the search button.

The other thing is, I don't see any temperature increase from sitting idle, my CPU/GPU will be the same temp from a cold startup or if it's been sitting idle all day, so if there were such a thing I wouldn't waste my money.

I think the idea is to do exactly the opposite of what your saying.
heat conduction is primary.

pure water is the best we can use, additives just make heat conduction worse.
theres another liquid made by 3M, with a posh name but thats just not likely to be used lol ( price)

that is no way to have water thermal proprieties changed so radicaly with only an additive, to get a better proprieties you need to change your coolant all together and that will generates higher costs (1$can for 2 gallons of distilled watter is pretty hard to beat).

The problem with heat transfer really isn't how much heat the water can hold (specific heat capacity) but how quickly that heat can be transferred. That's why water works so well.

The water isn't sitting in the block for very long at all, so how hot it gets isn't a big factor. Water doesn't heat up more than 1*C on its way through the blocks in your loop. If you could find something that absorbs heat from the blocks even faster (heats up more) it would also dissipate the heat faster at the radiator, too, and then your system would perform better.

I use a additive that does just that, But it is highly conductive and frys everything it hits if you have a leak. I use Chelated copper as a algeside (about 10 to 12 percent)and as a added bonus it improves the thermal transfer to boot.

doesnt that tear up the pump? i could never do that, that is ultra risky.

Copper? Do you just get some old HSF and grind it to a pulp?

Chelated is that like removing ions? Like EDTA?

Copper would kill most bacteria.....

Bit worried about the pump tho

There are some liquids that come close, or even beat water in conductivity, but they are generally more viscous and require a more powerful pump to get the same flowrates. Less flowrate = worse temps. Bigger pump = more heat dumped into the loop.

I filter the chelated copper liquid through a coffee filter befor adding it to my loop. I also use a iwaki rlzt20 to push the fluid through 2 pa160's in paralel to the storm G5 then a fusion HL keeps every thing cool. No problems yet.

This is what I use http://www.appliedbiochemists.com/cutrine.htm

There are better things that you can add, but this list includes things like mercury that just won't hold up in the current hardware, being that the substance is corrisive or just simply dangerous. For these reasons, "pure" distilled water has always been the ideal liquid.
