A one molecule thick layer of corrosion inhibitor probably won't have much impact on cooling because in most cases there is a
boundary layer of substantially greater thickness, where the water is flowing very slowly (if at all). Heat has to get through the boundary layer by conduction anyway.
A thicker film buildup (which can occur with WW) is a bigger problem.
However, "bad" is a relative term. Compared to the aluminum top corroding through on a waterblock, how "bad" is slightly reduced heat transfer?
BTW, I don't know if a "good" corrosion inhibitor only produces a one molecule thick film over the metal components. I wish I knew of good in depth information on corrosion inhibitors.
