abit IC7g cooling question

I just got my new setup 3.0c and abit IC7. Im planning on doing some moderate overclocking with this rig but Im wondering if the Northbridge needs better cooling. Has anyone seen better results with different alternatives. I might just WC the CPU and the NB but not to certain yet.

It is not needed to add/change the NB cooling unless you reach serious FSBs... But that is hard to do with a watercooled 3.0C...
