The damn things have super glue and wont come off unless you use a knife -- not easy.
Also, use some artic silver on there instead of the default crap paste.
Then you'll want to use ATI Tool to set the fans to run @ 100% when above a certain C* threshhold.
Another thing, when you remove the Heatsink, you'll see something written on your ram. If it says BJ11 then it has x1900xtx ram! If it says BJ12, then you have normal XT ram. If you DO have BJ11 ram, I have a special bios that will OC your card without tinkering with anything and has faster fan so no need for ATI tool:
My custom bios
Hmm, this makes me want to write up an x1900 newbie guide.
