Thermalright designed the heatpipes in this heat sink a bit different. Thermalright states on the web site that orientation of the tubes does not affect the performance. They also claim that the wingspan hanging over the mosfets and Northbridge chip will reduce the PWM temperatures as well. Thermalright also claims this is the first heat sink that configuring either suck or blow will net less than 1% difference in temperatures.
