Zalman NB47J. Bend some fins and it'll fit fine.
Ah... don't be afraid to be the first to resort to violence. I'll give that a try if the Thermalright doesn't work out.
If you want to replace the fan, how about the Thermalright HR-05 SLI?
Looks promising. Do you have idea how tall the base is, though? The link at http://www.thermalright.com/
doesn't really say how high up that goes.
Ah... this page http://www.pcmoddingmy.com/e107_plugins ... tent.385.3
suggests it will work with my mobo. Here's hoping!
I wouldn't have bought the mobo if I were you... can you exchange it?
At the time I didn't realize how loud the chipset fan would be. Now it's a little too late... especially since when I installed the new chipset fan, I accidentally "modded" it by snapping the VGA retention clip. The mobo still works, but now the VGA is only held in place with the screw.
Thanks for the tips, everyone!
