To anyone considering cooling any of the following; North bridge, South bridge and MOSFET's. I've provided a few images below in regards to removal. The passive stock cooling that comes with the board is actually one piece, so if you only want to water cool say the North bridge, you're going to have to modify the stock heat sinks (by cutting the heat pipe that connects all the sinks).

The MOSFET's come with pre cut thermal tape stock, the North bridge and South bridge come with pre cut sheets of thermal compound stock.

The stock cooling is held down with several spring loaded pins (removal described below). Depending what your goal is, whether it is to just replace the stock compound on all the sinks, or if it's to water cool, some or all the chips, this should give you a bit of insight.

Sorry if the images are slightly blurry, my medication causes tremors.
