You'l get much better heat transfer with nb attatched with screws and nuts. Attatch 60mm fan with long sheet metal screws screwed between hs fins. For the south bridge put 4 12mm mosfet heatsinks on it. I've ran mine this way since december. The nb and sb get warm but nothing like they did at stock. I had to file down the 2 bottom hs on sb so vid card would fit.
Well I took off the 40mm fan and fitted a 60mm panaflo fan and it made zero difference to the temps, gonna have to take out the entire board to refit the heatsink with better thermal paste.

I actually have those exact silver heatsinks shown on your pic (3x3 fins) but the stock TIM that came with it was used before (old gfx card).

I'm not sure if I should use epoxy incase I need to RMA the board and risk pulling the entire heatsink + SB chip out with the epoxy stuff.

Still got this SB sink that recovered from my old NF2 board: http://www.sidewindercomputers.com/misiso.html

There seem to be high rates of the 6xxi boards failing right now, not sure these boards will survive that much longer with stock cooling!
