I can't tell you in terms of degrees, but I know how these things work so I'll do that.

I have a degree in Photography from the film days and we used a product called PhotoFlow - a "water wetter" - when developing film. It breaks down the surface tension of water used for the final rinse of film and causes it to sheet off without sticking to the emulsion and leaving spots. In an automotive application it would increase the slick flow of fluid through the engine and prevent it from clinging to surfaces. By not clinging, it should increase it's ability to carry off heat.

Disclaimer: I use the stuff. I put zinc additive in my regular oil, too.
