Default Water cooling the P5Q northbridge

I have a P5Q Pro. My current water cooled setup doesn't direct a lot of air over my northbridge, and it gets pretty hot. I've been thinking about buying a Swiftech MCW-30 chipset cooler, but I'm leery about removing my stock cooler, because I'm not sure how critical the mosfets under the heat pipe-section are, or how I would cool them.

Does anyone have any experience with this?

Possibly another reason why that block wouldn't work is that there are capacitors in the nearby vicinity. This is similar to my Asus P6T board.

The heatpipe problem is also an issue. As of yet, I have no idea how to solve it. I'll post anything I find on this subject. Just thought I'd post to let you know that I'm also having this problem. =]

To cool your mosfets you can get a ThermalRight HR-09 U TYPE2 for the set closer to the rear panel and a HR-09 S TYPE2 for the upper mosfets. EK-NB S-MAX and EK-NB/SB5 will work on the northbridge.

That first Enzotech cooler was exactly what I was hoping to find; I'm not sure how I missed it, but that you very much for pointing it out!

Thanks to everyone else as well for advice, and showing me I'm not the only one with these concerns.
