No, your video card is not running too hot! I'm telling you that it isn't. Look, I have 4 80mm fans and a PCI exhaust blower fan beneath my 6600 GT, and last time I checked it idled at about 60 Celcius and under load it got to about 80 Celcius... Gigabyte told me not to worry about it. Now, with that cooling setup, I still get those temperatures, and I have never had any problems.
