This is the smoothest board I've ever own. I've got my 3000+ Winchester running @ 260 x 9 on stock voltage. Idles at 37C, full load 48C using an XP-120. The board actually runs about 4C hotter than the CPU. Only glitch I've noticed is my -12v rail is showing -1.65v, and my +12 is showing +11.65v. This is with an Anetc Neopower. I know Antecs sometimes have flaky 12v probems, so I pulled out my 'meter. The -12v rail is spot on, and the +12v is showing +11.75. Weird.
