That temperature is safe for a high end nvidia card, is the card running at stock clocks or is it overclocked? If it has a factory overclock, which a lot of the 560TI 448s do, then the temps will be higher. If you want to lower the temps a bit, you can download MSI Afterburner and use it to set custom fan profiles, a more aggressive fan profile may help reduce the temps.
My 7950gt (old nvidia) runs up to 120c according to the monitor. Then I cleaned out the dustbunnies and it'll run up to about 110c. Either the monitor is wrong or it really is getting this hot. Doesn't seem to hurt the old tech much.
