Warning !!! Don't Buy Aluminium Waterblocks

[B.E.E.F.]

By forcing us to use additives, we lower the theoretical amount of heat that can be dissipated instead of having gone a 100% solution of distilled water.

Can't you use ammonia?

It has a slightly higher heat capacity than water. It also kills life, so its perfect to prevent algae and stuff in the system.

Or are most ammonia compounds corrosive?
