Southbridge Heatsink Removing Pushpins On Nb Heatsink?

Removing pushpins on nb heatsink? - southbridge heatsink

I recently purchased some 3rd-party chipset cooler on my northbridge and southbridge, but how do I delete one shares on the motherboard? Both are driven by screws.

I have to go through the difficult task of removing the motherboard from the box and cables from the removal of the screws from the underside of my motherboard, as it has done this sort of wedge-shaped?

Is there another way?

Help!
