The higher I ever seen was about 2 months ago ( fairly warmer ) in Witcher 2. It reached 57ºC ( the card is mildly oced 900 core from 820 nothing too shaby , I actually only noticed it now and I'm reverting it to factory default since I don't actually need more performance ) and that's in my msi afterburner fan control 60% ( 3300rpm , usually it won't be this agressive )
keep in mind I have made the fan to be more aggressive to earn some degrees , usually after some time in heavy games it could reach 60º during summer. BF3 reached 54-55º during beta
remember that I have the 560 TI Twinfrozn and not the hawk version.
I have assembled a pc with a HAWK one and it's the same as this , yes it can reach insane speeds and noises , but it never does in normal usage.
now I'm watching after 2h of wow it's 42ºC the best it can do ( max fan rpm it reaches in my config was 2000rpm )
Here you have some reviews of it talking about the noise levels :

This is a nice video and he actually shows the card running while recording @ full load try to hear it :P in a case , you'll probably never hear it untill you go and cranck the fan to 70% and go " ohh there it is !! "

found another video of him actually playing on his MSI 560 Ti ( the card is not inside a case so the noise is greater , even without it it's barely audible )
