Good job, thanks for letting us know how it turned out!
Oh, and in general, Globe fans are pretty good. You may want to try and re-mount them with a soft mounting solution like the ziptie method (explained in that thread I linked to) or some soft rubber mounts (but not the Sunbeam ones).
120mm fan recommendations:
12v: Nexus Real Silent, Akasa Amber, Scythe S-Flex 1200rpm.
Undervolting: Sanyo Denki 120x38mm, Delta Triple Blade Low Speed 120x38mm.
Akasa and DTB can be found at sidewindercomputers.com

The others can be found all over the place, just find the best price. Pad your order(s) with sleeving, fan screws etc, light things that won't add any more for shipping.
EDIT: No, the 9500 doesn't help cool the northbridge. If anything, it's much less effective at keeping your ram/northbridge/mosfet cool, but the CPU cooling is worth the few degree difference.
