I forgot to comment on the question on cooling fans.
If your 9600 looks like
this it should not need a fan and never had one.
Your 7500 should look like
this and also does not need a fan and also never had one.
There are other AIW 9600 versions that did come with fans. You can find them by scrolling down at either of those links.
Capturing video will not stress the GPU much at all. The Rage Theater chips are doing the work and will get warm but I've never read where anyone recommended adding a heat sink or anything. Just do what you can to provide good airflow through the case and leave the slot open next to the video card and you should be fine.
