Could I cover them up with the provided insulation strips instead? If I place them vertically that should be fine right?
You could to be safe, but I held a plastic CD sleeve in between on assembly as to make sure there was zero contact with those two chips with any heatsinks.
You could possibly swap your whole 7970 heatsink(minus the shroud), with some nice person that still has two of the original 5870 AC Extreme's and the 3 heatsinks in the pic above though for a 100% perfect fit onto your 5870, as the heatsinks on the 7970 are god awful rotten in comparison with the older 5870 Extreme supplied heatsinks.
