Which liquid for cooling?

[Kekewy]

I know they make oil based liquids for water cooling that won't damage the components should the system spring a leak and that doesn't have to be changed very often. I read an article that said they needed to be changed every 6 months to a year. However I can't find the article and I don't remember exactly what type/brand of liquid was mentioned. Can someone point me in the right direction? Either the article itself or the type of liquids mentioned in it.
Thanks in advance!

ummm...

all liquids become conductive over time.

Its not the liquid itself, its the dust particles which lay on top of your eq.

When the liquid gets in contact with those dust, it becomes conductive.

The higher the viscosity, the lower the performance on liquid as well.
This is why oil is not a great medium for transfer at the temp levels we look at for computers.

The best liquid one can get when your keeping to simular metals... ones which dont have a galvanic reaction to, is straight distilled with some form of anti microbe.

If your mixing metals, then you will need an anticorrosion agent.

With the large parts one can get today in water, you should not be mixing metals which can lead to galvanic corrosion. Example: Copper + Alu... Copper + brass is fine, and Nickle as well... Copper + low quality steel may cause problems.
But its mostly Copper + Alu which will cause Havok.

Just use distilled water. Add a tiny bit of biocide from walmart or petco or w/e into it. There's no reason to use anything else (unless you absolutely must mix alum and copper but try to avoid that).

When you make your loop leak test it overnight with power disconnected from the mobo and video cards. lay out some paper towels to make leaks obvious. Run the pump overnight like I said, then in morning check for leaks. Double check to make sure fasteners are all tight, and then you should be good. It won't leak. We all make mistakes attaching things, but that's what testing is for.
