NB fan replacement

What have you used to replace your chipset fan on the AK31 3.1? That capacitor looks like it is a real PITA. Has anyone succeeded in getting a crystal orb or blorb to fit? The NB fan seems like it is a fairly common problem, so I'm interested to see what solutions people have gotten to work.

all i did was pick up a chipset cooler from radioshack and stick it on there. perfect fit, and it's thicker with a better fan on it. will be watercooling it eventually.
