Best thermal paste for g80 gpu :)

Hello all, i was wondering if anyone could give me the name for the best thermal paste to put on my nvidia 8800 gtx gpu i took off the cooler today and cleaned it and put titan nano blue thermal grease on it and to be honest it is rubbish 56 idle temp with 100 percent fan control so you see i want to replace it as quick as i can any ideas? also can i put the paste on the memory chips of the 8800 instead of thoose pads? cheers all

The general consensus on thermal compound for CPU's is one that is made by Arctic Silver. I can't see why it'd be any different for GPU's.
