This cooler claims to have thermal rating of 250 watts. My card's TDP is supposedly ~220 watts. Would I still get good load temps if I were to overclock with a voltage increase? The card's stock voltage is ~1.0 and I wanted to use a profile with a voltage of 1.075? Would that push me beyond that cooler's thermal capacity? I don't want my temps to go above the upper 70's since that card has been notorious for having its VRM's explode.
