Cooling northbridge?

[9761]

Hi,

I have the abit IC7-Max 2 motherboard and I would like to overclock my CPU later, but also I would like to make it quiet.

Could I take off the northbridge fan and leave it as it is and overclock or would I have to put a zalman heatsink on it?
If I have to have the zalman on the motherboard is there any way to get it to stay on as on the motherboard it has 4 loops whereas the zlman needs to holes with rivets to secure it down?

thanks

my current one is held in by 2 clips that hing onto 4 loops.

heres a pic of what I mean.
