MSI 4850 OC edition. Does this card come with a better cooler?

Hey i've just build a rig with sapphire 4870. Want to ask a question here.

I play crysis at high setting and it runs smoothly. But after play for a while, my pc hang . Need to restart. What's the cause? Is it because the card is too hot? It's 77'C when idle and 82'C when load, watch the temperature at CCC. Or is it because of the driver problem? Or because the game problem itself?

And is the temperature ok? I use gigabyte odin 800W.

I use 2gb team xtreem in vista. Mobo biostar tp i45. All brand new items. Other games- neverwinter nights 2 played for a while.Will play for a longer period after this. Will find more game soon, from my friend. I use ATI catalyst 8.6.

Gigabyte odin pro 800w.


Increase? What speed do u recommend? i read that increasing the fan speed is quite noisy. I wonder what's the default speed.

ok.. will change it when go back to my room after this

Owh should i install 8.9? Too lazy to fix if got problem.
