There's a lot of chatter about the noise generated by that 40mm fan on  
the osx86 fora, since that is a popular board to turn into a  
hackintosh.  Some suggest just putting an 80mm in there pointing at  
the side of the heat sink, others recommend an after-market 40mm that  
I don't have the link for at the moment.

Others have modded aftermarket heatsinks so they can be attached, but  
that probably goes a bit further than is wise, IMO.

I'd lean towards some sort of chimney adaptor that allows you to go up  
from 40mm to 80mm like there used to be for 80mm to 100/120mm before  
we got into all these fancy heatpipe-flowery thingamajigs for heatsinks.
