For what its worth... Royal Purple has a product called Purple Ice which increases the surface tension of water a bit.

I would think it would decrease the surface tension. Yes?

The general concept of lowering surface tension in a closed liquid cooling system is that the water can more easily flow into micro voids within the heat exchanging surfaces thus increasing the efficacy of the cooling system.

Water naturally loses its surface tension as it is heated. The old float a needle on the glass of water trick does not work with hot water due to the reduction in surface tension. But often an electronics cooling package will not get to a sufficiently high temperature to benefit from this effect so some have found that adding a surfactant is helpful.

I never make a mistake. I thought I did once but I was wrong.
