Bought a Sapphire ATI X1900 XTX and love it. Want to know how much can I pump it up on stock fan. Also would like to know the best cooling solution out there and how much could I max on that. Tried using ATI Tools - program for overclocking - auto max function and temp when to 82. Got scarced and never used it again - scared of screwing up my card. (as u can see am a newb when it comes to overclocking cards ) Hope you all respond. Thanks.
