Not experienced with an IPA on pacman at 78F, but as a point of reference: I just moved my two stouts to secondaries after two weeks in primaries, and several additions of cherries. The pacman that had got to 72 (on the fermometer, so maybe 75 internal?) was delicious prior to cherry additions - really rich coffee flavors, and I didn't get any frutiness. The Wyeast Irish that probably got to the same temp had a little fruitiness to it - again before cherries.
I'll have to try it again sometime without cherry, but I had my mind set on a good load of chocolate cherry stout in the cellar for several winters' enjoyment, and I'm stubborn...
