What block for integrated GPU?

Looking to water-cool my HTPC so I don't have to hear all the fans. Looking to get a Maze-3 or similar, but I am not sure what to use for the chipset. The board is Nvidia IGP based, will it accept a "standard" chipset block? What do you recommend?

Trying to keep the budget down so nothing too expensive or my Wife will kill me

I've got a Soltek motherboard with Nforce2 chipset and integrated graphics. A zahlman passive with some airflow is enough for my northbridge which actually does the integrated graphics.

Based on that, I'd think any chipset block would work well if properly mounted; get one that isn't restrictive. I recall reading that some people had problems with Nforce2 northbridge chips not being flat; use just enough thermal paste for complete coverage of the water block.

I've decided not to WC the NB chip on my system. I have an 80mm fan in the side of the case that blows enough air at the NB and it's pretty quiet.
