Bigger, heavier, more fins, more heatpipes... wider heatpipes? Yes, there are also manufacturers who will try this approach in the not-so-everlasting search for the ultimate in air cooling. In this case, the two models reviewed feature heatpipes measuring 8 mm in diameter instead of 6mm.
As their performance indicates, increasing the width of the heatpipes is not definitive, but it sure helps both heatsinks to keep up with the current champ (the Thermalright Ultra-120 eXtreme). If you get price into the equation, the Xigmatek HDT-S1283 wins thanks to it's own inexpensive fan which almost matched the Scythe Minebea 4710KL-04W-B29 fan. The heatsink is cheaper in itself, but if you add the price of an aftermarket fan (for Thermalright's offerings) the gap is considerable.
All in all, air cooling can get you very decent results with today's most powerful CPUs
