The water pump is belt drive by the engone and 2. The tubing is much bigger than you will find in a computer setup so the thicker fluid would pump much easier. I think the Antifreeze at -40 would burn the pump up. As far as Ethanol mixtures, you can find seals and gaskets that are compatible with Ethanol such as Neoprene, Teflon, Polypropylene, Nitrile, Viton, etc. HERE is a page showing some chemical resistances of certain materials.

Edit: What about Acetone? Isnt that used as a Dry Ice medium when DICE OCing?
That is what I am concerned with on either of the glycols. Maybe a stronger pump like an Iwaki RD-20 or RD-30 could handle it? I will have to do some more research on the ethanol. Should be okay with copper/nickel waterblocks and the right tubing. Just would need a "safe" pump.

Nice OC on that 2700X!
