have you looked into fluidxp+? It feels like oil.
When talking about computers, NOTHING cools better than water. It is the benchmark everything else is measured against. It has a thermal coefficient of "1". Anything you add to water will negatively effect it's ability to absorb heat. Additives such as Water Wetter, Zerex and antifreeze with a "anti-foaming" ingredient will lessen the negative impact, but not improve heat absorption. In rare cases, at very high temps and pressure anti foaming agents will minutely improve the heat transfer of water, mixed with a heavy mix of glycol it will significantly improve heat transfer. Neither of these conditions will ever happen in a comp.
The trick is to add just enough additives to prevent galvanic corrosion and biological growth. And as little as possible to maintain heat transfer. Generally between 5 and 10 percent additives mixed with distilled water, and changed on a regular basis, is optimal.
I recommend the above mix for several reasons. One, it's cheap and readily available. Two, it's proven itself to work very well over several years of constant use and will not damage equipment. You can spend more money on high priced additives, but you won't be able to measure a significant difference over cheap antifreeze.
^^^ What he said.. woot i dont need to write a long post!! :p:
how about liquid metal cooling ...nanocoolers?
for that same reason, the volume of water (in its liquid state) is also pretty constant and so wont pressurise your system
this is an interesting table - http://www.dow.com/glycerine/resources/table13.htm
if you could determine the temp of your water, you could modify the ratio to increase performance, non?
You could if you use glycerine, which I don't think many (any?) do.Quote:

Deuterium has a higher specific heat capacity. Viscosity is slightly lower though.
Deuterium Oxide would work better than water.
But I think even a couple of litres for a watercooling rig would be quite expensive..
Unless you have a supplier?
what about a loop with mercury running through it :p
Yea, but then we'd never hear leak reports because the people who got them would be poisoned to death.
Yeah, Mercury is very dangerous and evaporates really fast. It gets absorbed through your skin fast and intoxicate your blood, and when evaporating you can inhale it through your lungs and get intoxicated also. This is some pritty dangerous stuff :caution:
It would have to be in a air sealed loop.
Im guessing the safest way would be to have the case in a air tight room and whenever you get in you put on your special suit or something like that.
Would be nice to hear from a professional on this, tho.
Probably someone with experience could try it. :D
Too heavy, extremely low specific heat capacity. Water is better.Quote:

lol, I wasn't really serious, and yet people attack it as if it were a feasible option, I thought the tongue sticking out would give that away :p <---- see :D
People have seriously suggested it though. Bottom line is mercury is far too dangerous for home use.
Lower viscosity is actually a good thing (when it comes to cooling).Quote:

Wikipedia claims the viscosity is 1,3 x 10^-6 Pa s; this is more than 'normal' water.
also, how do you release the heat if everything is metal? Wont the heat spread fast? And since its heavy, what pump can push push it?
I've been trying to get a red color for my liquid............I've decided to go with human blood, I think that'll be good for cooling.
