Mosfet Sinks on P5WD2-Prem

Can someone tell me which are the one's I should sink? I am not even sure I know what are the Mosfets.

There are 4 little flat black chips across the top of the board, grouped in twos. 2 on thte top left corner and 2 on the top right corner. Is this what I need to sink?

Anyone have a pic that would be great!

i also wanna know this too

ok the answer is:

The 4 sets of flat black square chips just above the socket. There are 2 together in each set for a total of 8 chips

Usually just touch test them and what ever is hot. Mostly the ones by the cpu ram and videocard
