Temperature sounds reasonable to me, the Bios one that is. I have a Gigabyte GA7VAXP with a barton 2500+ and it runs between 49 and 55, danger point for the CPU is 85 so no worries and its totally stable. I think the problem with Sandra is its designed to try to give you info on any motherboard and that my be incredibly differcult. Why not try Gigabytes own system monitoring tool Easytune I think its called should be on your driver disk under tools and see what it says. Or you could download it from their website.
