Get the 80x38mm Delta Focused Flow fan. Yeah, it's loud, but tolerable with the cover on and the box under the desk. If you get a rheostat, you can turn it down when you don't need full cooling power. I think SideWinder sells them.
And yes, there is always the superior Hoot Chute aka Cohesive Air Cooling. ;D
