Liquid coolant?

[uniman6699]

hey guys
i jumped online had look and decided that i finally have enough money for a water cooling system that i have been longing to get
Black Ice GT Stealth 360 Black x2 $130.00 copper
EK-FC580 GTX+ Acetal Nickel x2 $250 (for my 570s
EK-Supreme HF Plexi $79.00
now wat about the coolant i have looked at forums but none of them suite my situation (Australia plays console unfortunately so pc gamers like me dont get alot of variety)
my CPU waterblock and radiator are both copper but my VGA block is Nickel so wat coolant is fit for my setup?
if u guys now of a site that ships internationally pls leave a suggestion i am really feed up of paying 10-50% extra
thx in advance

Distilled water and a biocide; silver coil, PTNuke.

1. Distilled water is the best coolant.
2. Corrosion blocker if you're worried about the different metals in the setup. (one 50ml bottle treats two liters of distilled water)
3. Silver KillCoil or PT Nuke to prevent anything from growing in the loop.

my main concern was the different metals? any suggestions?

I used Feser brand -- Feser Base Corrosion Blocker. I don't know whether I actually need it for my loop, but I figured better safe than sorry. It's a tiny amount, so you don't need to worry about it affecting temps.

There's no aluminum in your loop ,the Anodic index of copper, brass and nickel plate is so low that there is no need for concern.

thx guys i got a 800D instead of silver-stone Rv 02 and a 590 water-block (obviously the card aswell)

 

[uniman6699]

plus thx delluser 1 i went with PTnuke 10% and 5% dye and 85% distilled water

I recently read in MaximumPC that there was little or no temp difference between a "high end" coolant and distilled water.
