i really like the idea of the heatpipe/heatsink spreader instead of using the fans to cool the chipset, i hope more manufacturers will incorporate that into their boards.
and the best part of those mobo's is that if you have a big cpu heatsink, like an XP-90 (like mine ) or XP-120 it usually fits right over the heatsink for the chipset, like they were made for each other and cools amazingly, it's gloooorious
