There are a few posts covering this already somewhere in this thread.
NB --> HR-05 SLI/IFX or just a regular IFX depending on your CPU HS configuration.
SB--> Same as NB unless you are running CF then you'll need something low profile like
this.
I use the SLI/IFX on my NB w/ fan and I sit at 40C while running OCCT w/ NB @ 1.57V and 34-35C @ idle.
I have the Enzo I linked to on my SB w/ 1.075V and two HD 2900XT's sitting on top of it and it sits at 37C under load and 34 @ idle.
The heatpipe assembly actually comes apart in two pieces so if you remove the NB/SB heatpipes you will still have a separate set covering the mosfets to the rear and top. You can also remove this part and use two HR-09's type 2 to cool this area which is what I did.
