New Motherboards & NB waterblocks

I'm wondering if anybody has taken a spare radiator and just hooked up the NB Water blocks that come on a few high end motherboards these days. I am, of course, talking about hooking it up completely passively, just rad and the block.
Would love to see what kind of performance this offers.

There is no point to doing that, people would rather just run a passive thermalright cooler.

What you are talking about is called a thermosyphon. There was an article on overclockers.com about it somewhere...

wow, I remember when I saw that article on the front page - can't believe it was that long ago!
