Hey everyone, Hope you are all doing great...

I am here today to ask about what can I use in my Liquid cooling setup for my CPU other than water? I don't want to use water because I am setting this up for the first time and I don't want any kind of leakage in there, but let's face it, sooner or latter there is gonna be one somehow... :(

So I am here with my Three fan Aluminum Radiator, Two water Pumps (One to push and one to pull), a Water Block for my CPU and about 20 Feet of Tubing to set it all up... I am thinking of building a reservoir myself like an Aquarium with at least 4 liters of Capacity... What would you suggest for the coolant in the system other than water, that has good heat transfer, and is low viscosity like water, but is no threat to the Silicon if it somehow finds a way out of the Circulatory system???

Thanks in advance for all your time and effort...

We used to clean small electric motors by running them submerged in isopropyl alcohol. But there's the flammability of the material to consider, and I'm not sure how will it accepts/sheds heat. Ethyl or isopropyl alcohol, in nearly pure form, will not conduct electricity. Not sure how pure it would have to be. Too flame-y, at any rate.

Look... no matter what you run it's gonna pick up bits of dust, microscopic particles of the tubing, radiator, and block which will make it conductive over time.

Just use distilled water.

Also water has about 2-3X better thermal conductivity and way better thermal capacity than any specific chemical for your operating temperatures and components. Hell the only thing that comes close is ammonia and you're operating well above it's boiling point.

There ARE commercially available non-conductive coolants for liquid cooling PCs but all of them have horror stories just like water and most are simply distilled water with an anti-microbial agent. So... screw it.

Distilled water has little to no conductivity and is what the majority of commercial 'coolants' are made of. It's only once it picks up other particles/contaminates that it becomes conductive. The only way to avoid the implications of potential leaks is to go with air cooling which lacks the ability to leak. Unless it's a situation where crossfiring or sli of 2-3 or more gpu's where traditional air cooling can't keep up, for things like cpu cooling most modern processors can be effectively cooled with air cooling without issue or limitations. For instance intel chips where core voltage becomes an issue far before temperatures become the limiting factor.

Distilled water is actually a very poor conductor of electricity. When it, or any other solvent, gets into computers it's the metals, dust, and crud that they dissolve that makes them so dangerous to the electronics, plus any corrosion which ensues. The currents can be quite high, but the voltages are low. All things considered, nothing more inert has anything like the thermal properties of water.
