The mosfet run cool on 45nm quad no need for waterblock. But it other story for 65nm quad.
Just boltmod them using short M3 screw and with EK Asus 3a backplate if you worried the board gonna bowed. Thermalright HR-02 S/U also fit the mosfet but no need for that because the gigabyte heatpipe can be pull off the nb block or the mosfet block.
SB dont need any wc. Just replace the tim.
I think EK-NB/SB 5 should fit the board because the mounting holes on the nb is around 64mm. I`m using zern.
