Can alcohol cool a pc better than the water it's self?

not possible.

you need massive volume & gas pressure to crack anything

it is not the pressure. It is the evaporation of alcohol that causes cracks in acrylic. Then fluid changes phase from liquid to gas it absorbs energy. thus "freezes" the very top lair of acrylic and cracks it.

a few points to be clear:

- liquid gets enough heat energy (not needed to meet boiling pt) still gets vapourized

- vaporization only occur at surface of liquid . only bare minimal ring of container is in touch

- vaporization of liquid brings away heat energy from loop, will not lower the temp to freeze anything, and the temp change is very mild

the crack happens then you drain the loop!!! not then it filled up with alcohol fluid. to be on the safe side it is better to use all metal loop.

if you want to see how it works wipe a pice of acrylic with vodka. I ruined head lights on my car this way, filled up the wind shield washer tank with vodka. could not get any proper fluid during winter at 4 am in the morning, but vodka was cheap enough to get a couple liters and carry on driving.
