Ok recently I posted about my xfx 9800gt card getting hot getting up to 99c. it was suggested to put new thermal paste by both here and xfx. today I decided to do it had everything I need and couldn't get the fan off.after I remove these screws with spring from the back of the card there is like screws on the other side but no way to remove them. the fan will not pull off and didn't want to apply to much force. any ideas how to remove the fan?
