Coolant Mixtures - My Own Findings

[Hesky82]

Hi chaps, well I’ve spent absolutely ages testing many different coolant mixes over extensive time periods and I’ve come to the conclusion that pure distiled water and a couple of drops of concentrated Biocide is my most effective coolant mix to date!

I’ve given up on hydrophilic absorption promoters like Redline Water Wetter and Valvoline Zerex due to their general ineffectiveness. The stuff never lowered my cars coolant system temperatures so I’m not surprised it didn’t work in my pc. Zerex is the most annoying stuff as I have found it creates a nasty white film on the inside of tubes.

I’ve also dumped using corrosion inhibitors such as Pentosin G11,G12 and other coolant additives, I found you just don't need to use them in a cooling system that has no aluminium components, so adding additives like this that contain ethylene glycol really has no positive effect on increasing the coolants heat capacity.

Pretty much all the different types of uv dies I tried faded after quite a short period of time and I’ve even had a few types sludge up in different watecooling loops. Real nasty!!

And finally I’ve also tried a few pre mixed solutions from Feser and Alphacool and found distilled water actually cools more effectively regardless of their specified heat capacities

Would be interesting to hear any comments.

Cheers

Next step is to try some laboratory grade double-distilled water "ddH2O" which a dear friend managed to pinch from work, should be able to do away with the copper sulphate biocide completely then

I change my watercooling loops so often I couldn’t justify using those crazy expensive non conductive coolants. Probably the only stuff I havent tried yet.

In simple terms its basically a type of high pressure filter that removes most of the impurities from tap water.
