Can't remove southbridge heatsink on Asus P5Q Deluxe

[simonslothtour]

Hi

I'm building a 2007-ish computer and just bought this board. I want to apply fresh thermal paste to the north- and southbridge, but I can't remove the heatsink on the southbridge. I have loosened the two plastic screws so that's not the problem.
Am I supposed to remove this? Is it because of old dry thermal paste or is it simply not possible to remove?

The only part that can be removed if I recall correctly is the CPU heat sync. I am not sure the south bridge has themal paste.

The SB uses thermal tape/pad that's self adhesive, not paste. The only thing that's really ever been modded for that heatsink is the inclusion of something like a 20-40mm micro fan, and thats only in cases where that particular heatsink for some reason is being overworked.

Okay, thanks for answering. I thought I could replace something there as well, but I'll stick to the cpu thermal paste
