nf7-s chip cooling

i was just wondering what all chips on the nf7 can use some passive heatsink cooling.

northie - obviously
southie - gets northie's fan
mosfet - passive gforce fx5200 hs
anything else?

would cooling the sata controller possibly give slightly more stable sata performance? what about the winbond chip near at the top of the board between the cpu and ram? or the attansic chip and various other chips near the mosfets?

just wondering as i have some extra heatsinks sitting around and a bored dremmel.

kthxbye

Extra cooling would not hurt anything...could only increase stability and max overclock.
