With the current cooler you are using i would govern the cooling to blow away from the board so the you cpu heat sits above the heat-sink, from there the front and rear fans should do the rest of the work for you.
Frostytech's test bench is the LGA 775 platform. As the current CPU's have a completely different heat signature, Frostytech's data is irrelevant. It has been conclusively shown that heat sinks perform differently with different heat signatures..... the machining, heat pipe orientation must be optimized for the chips die size, shape, core locations, etc.
FrostyTech's Mk.II Platform delivers a 150W and 85W heat load to socket 775 compatible Intel Pentium 4/D/Extreme Edition, Celeron, Core 2 Duo & Core 2 Quad class heatsinks by way of a 30mm x 30mm copper interface die.
Look for test sources which use the CPU platform you are using for accurate results.
Some HS's are designed to blow down and cool the memory, MoBo chips etc. The Coolermaster Gemini and Prolimatech Genesis fall into this category.
Most coolers however are designed to blow up. Among the bet of these are the Coolermaster V6 GT and the Thermaltake Silver Arrow. If ultimate performance is your goal, the GT is the choice.....if noise matters, you give up little performance for dead quiet.
