While the board layout follows AMD's reference design completely, sporting no additional power connector but support for a CrossFire configuration via the usual multi-GPU connectors, ASUS have chosen to go down their own route when it comes to offering a cooling solution for the board. While the EAH5670's cooler can't quite be considered a single slot solution, it is a relatively low-profile one, which ASUS claims to be "dust-proof", thus elongating the board's lifespan by as much as 25%. While we can't really test those claims, the cooler's design should at least reduce the build-up of dust somewhat, which could be good news if your system tends to suffer from such "ailments".
