Does Redline Water Wetter make a difference or will any surfactant do just as well?

[Nvidiot]

I'm upgrading my radiator from 5x7x1 w/ 3/8" od to 6x6x2 w/ 1/2" od. While I have everthing apart I am wondering if it will be beneficial to add water wetter (Redline) or if it is a waste of time and money. One poster here said silicon tubing absorbs any additives. I've never heard that, but that is the tubing material I am using. I also read this article which tested redline vs dish soap! Table 2 shows that the surface tension and enhanced cooling were about the same between water/wetter and water/soap through the range of temps a pc cpu is normally in 90-150 F. Has anyone tried 1 oz of dish soap per pint of distilled water or is everyone using wetter only. Does it make a noticable difference? Looks like wetter only matters at the extremes of water temps. Who would know more about this? Are there other forums you can recommend to get this answered. Any thoughts on this matter are greatly appreciated.
