WC your northbridge worth the investment?

Hi all; I'm about to upgrade to an NF7-S and plan on cooling with a Maze3 and was wondering if water cooling the northbridge as opposed to stock air cooling makes enough of an OC difference to justify using it.
Anyone have any experiences air vs wc an nForce2?

I don't know if water would improve it, but my NF7's good to about 230 without anything but the stock orb cooler.

It's not really worth the extra money and flow resistance unless you're planning to go for really high FSB's(like 230+)

The stock cooler is alot beefier than people give it credit
