Coolest running graphics card

[sprtnbsblplya]

I'm looking between an x600, x700, Geforce 6600, Geforce 6600GT for an AGP 8x bus.
I'm going to put it into a crowded Shuttle XPC case so I need it to be cool running, so which of the above runs the coolest?
Also, I'm planning on using it to run Half Life 2, Morrowind: Oblivion (when it comes out), and World of Warcraft. I'm not super picky about running it at max res with shaders and AA and all that stuff on high, just something decent.

6600GT is the card i would recommend....

my one idles at around 50c. and 56c under load....thats stock cooling

my x700 performs well, but I it gets hot. I wouldn't recommend it for a shuttle.

Well it's kind of hard to say which one will run the coolest, but I would recommend the 6600GT.
