replacement coolers for 680i nb/sb?

[sabregen]

anyone know of non-backplate mounted coolers (passive heatpiped, or active) for the 680i boards? specifically the 680i A1 from eVGA? I am expecting my new board today. Case is an antec 900 maxed out, with all tri-cools on high, for reference.

There is a Northbridge cooler by Thermalright i think called the HR-03 (could be 05? please correct me if so) that's supposed to be pretty good. Should be a few forums or reviews around here somewhere for it.
If i get a bigger case, i'll most likely go with it as i don't have a huge amount of room in my case atm.
