That is, can you run a higher clock at 50C than 65C? Many of these cards run fairly hot. Does juicing the fan or putting them on water let then run faster or just add safety margins?
Also, does water cooling the memory help? Full cards watercool the memory. Modules like the Dtek GFX Fuzion that can be used on different cards use heat sinks on the memory. And even an EK or other full card uses a heat sink on memory on the reverse side of the card.
