1.26 for 4.3 is fantastic to the point of questionable (as in, I bet you could find a non-prime95 use case that could crash it, but if you haven't seen it crash yet, then go with it).
As for whether you are guaranteed big "gainz" by adding water, the answer, I'm afraid is very much no (guarantee). At or above 4.3 these chips go exponential in their requirements for voltage and some just won't do it.
You will get lower temps and potentially less noise as a result with the right setup, but don't go into this expecting the only thing between you and 4.5 is water.
1.26v/4.3 80C on a D15 sounds a little odd though too... 1.26v 6900 should be pretty tame heat-wise unless your fans are set to silent. Is that adaptive or fixed? If adaptive, then VID might be overriding and you are actually running at higher voltages than set in the bios (check aida or hwinfo).
Unless of course, that's AUS w/o A/C, so your ambients are high?
