I got some OCZ Freeze and put the old cooler back on the card. The temps dropped a good 10 degrees on load from before. The volt mods still don't appear to be doing it for me.
I shaded the memory resistor but i haven't gotten anything out of it. In fact I had to lower mem speeds to 1037. It's probably because this cooler doesn't actually provide adequate cooling to memory.
We'll see how it works out once I get the Accelero S1 on Tuesday and can actually put heatsinks on the memory, as opposed to the stupid styrofoam pads that come with the card. It seems like whatever ability the cooler HAD to cool the memory isn't there anymore (there was some liquid sitting on the memory chips when I took the cooler off, but that wasn't there by the time I put the cooler back on, which was at least a couple weeks later.)
