TBreak checked out this card and says it offers a very high factory overclock, with further headroom for even higher frequencies. It runs relatively cool and quiet at factory setting, but gets a little noisy when further overclocked.
"What we have here is a regular sized GTX 560 Ti with a larger than normal heatsink and the famous Gigabyte Windforce “Anti-Turbulence” fans on top. While the fans move at fairly nominal sound level (not loud, but not whisper quite either), they most certainly keep the GTX 560 Ti extremely cool. This is especially impressive considering the factory overclocked speeds of 1000MHz on Core (up from 822MHz) and 4580MHz on Memory (up from 4008MHz)."
