The other day i was tinkering around inside my computer and i noticed that the fan in my graphics card is acualy the loudest thing in my computer. I have seen many replacment heatsyncs for nvidia card but non for radions. what would be a good quieter fan that would sufficently cool my radion 9000. I saw this zalman fanless colling system at the store. Would this work with my graphics card, and does it work well? i have looked into thermaltake's cristal orb but it looks like it will be even louder than the fan i have now. Thanks for the help.
