So now ...

For cooling my Mosfet's:
(1) Part # cpu-tri-40 - Thermalright HR-09S Mosfet Cooler - Slant Type
(1) Part # cpu-tri-41 - Thermalright HR-09U Mosfet Cooler - Upright Type

For cooling my NB:
(1) EK-NB S-MAX Acetal block

For cooling my SB:
(1) vid-22 Microcool Chipsink Southbridge Passive Heatsink (Might work on the SB, but might be too tall)
-or-
(1) vid-84 Enzotech Forged Copper Northbridge Low-Profile Heatsink (CNB-S1L) (This is the one that takes moding to make fit. Sweet low profile and copper a +)

Not sure which one I will end up using?
Great choice, but remember, any passive cooling needs very very good airflow, it is critical, otherwise, they'll end to be unefficient too. Watercooling the mosfets, in my opinion is great, but definetely needs a two loop setup. With only one loop, the restriction will be too much and your CPU cooling will suffer. As, cooling the mosefets is an extreme OC issue, the few degrees the CPU temperature will suffer from restricting the loop could impact your CPU OC performance.

The price/performance ratio of the 2xHR-09 is by far better than watercooling the mosfets even without adding a second loop. In any case, they'll perform better than the crappy stock ASUS cooler (great for medium OC, but not enough for high OC on a quadcore)

As for the SB, the problem is that if you remove the stock NB cooler, you loose your SB stock heatsink, so yes, you need another heatsink. As I suggested before, and said by E.R above, the HR-05 IFX(/SLI) is a supreme option. For only the SB, I'll go passive, no fans needed. It easily fits a 80x25 mm fan too if really needed

I can't advice about the two heatsinks you mentioned, but for suere, they will be less performant than the HR-05 IFX or IFX/SLI versions
