I just recently got a Zotac GTX 560 (not Ti, yes I know) and it seems to idle really, really loud. It idles about as loudly as my last graphics card when it was under load (GTX 260). It get so intense in terms of fan speed, it started making my case vibrate and I had to jamb a phonebook up against it. I can post a video if you want. It generally idles at 60 degrees C and 1500 RPM. Under the heaviest possible load, 78-79 degrees C and 2800-2900 RPM.
