Water Cooling Liquid

[DotExe]

So I have been researching more and more into liquid cooling and thought I had it all figured out until it came back to really the most important element... the liquid.
So my question is, which liquid is the best?

[Drdeath]

Distilled water and PT Nuke(biocide)

From the Watercooling guide for beginners, distilled water and Hydrx work great.

I want the cool neon stuff so I'll be going for that, haha

[smduff]

The neon crap doesn't work or at least the stuff I got didn't

[Deton]

distilled water is the best medium for thermal conducting however the problem is bacteria will growth overtime in the system, alge occuring and corrosion will taking place if your water parts are mix materials, such as copper, alumminum...etc.

Copper and alum. don't like each other, but brass will be ok. However, copper will oxided when it contacts with straight water.

This is when PT PHN comes in play, it contains biocide killer and corrosion blocker, the draw back is no color if you are looking for bling. You can add color dye into the water but most color dye will break down quickly and cause clog in the system.

HydrX is works and afforable additive but you stuck with UV green color only.

they work unless you have strong UV lights though and must spread out evenly to see the affect.

[smduff]

I had two 12" UV lights above and below the loop, still didn't work

[Deton]

what coolant brand are you using?

are they look like this P180 Resurrection
as you can use I only have two 12" tubes, they UV do glow at the one close to the lights, maybe four lights will work better.

The coolant I use is Feser One.

I'm not really concerned about the coloring as i am the corrosive and thermal properties. I'm guessing distilled water with the additive drops will be the cheapest as well.

[Zankza]

I am just curious; what's the best? pure of those expensive ones ?

[Skyguy]

Distilled water and HydrX. Costs a couple bucks for the water, few bucks for the additive. Should last at least 6 months. Best solution, most cost effective too

[DotExe]

Sounds like a plan.

[Deton]

Listen, the thermal performance different between coolant available on the market is very minimal, somewhere from 0.5-1°C is the max.

So why those premixed cost so high?
Because you pay for the convienenice, the time for the development and materials.

Most of those coolants have additives added to the distilled water to help prevent the alge growth, corrosion and lubrication (for the pump).

Basicly, you can use automobile coolant for PC coolant as well but you must diluted very weak or you will loose flow rate of the coolant. Because PC pump can't handle high viscosity of the fluid.

Lol...I even used antifreeze fluid for coolant, of course it was for sub-ambient coolant project.

[Nyarlathotep]

This may be redundant, but what about using double-distilled water? Will that prolong the cycle so you don't have to change out the fluids as often?

[Deton]

what do you mean about double distilled water, you mean the mixing ratio?
