Any other programs to test?

ATi Tray tools (link in OP) has a decent artifact scanner built in. As does ATi Tool (Different from tray-tools and doesn't stress the cards quite so hard)

Mine is a bit of a golden chip. I am on stock voltage too. Game stable at 730. It's just an early reference design Sapphire.

For example, my 4890s idle between 44-51 @ 65% Fan speed. This is in an antec 902 with very good cable management. The high idle heat arises due to the poor layout on the UD3R mobo. One of the cards can barely breathe so it gives off heat to the second. Consequently, higher fan speeds are required. At 65 degrees I am already using 85 % fan speed. Anything higher than 70 degrees and the fans go to 100 %.

My 5870 Vapor-X card, idles at 28 degrees with a 40 % fan speed settings. That is improvement over the 4890s!! . My XFX 5870 XXX cards idle between 32-35 degrees celsius. Yet again, improvement over the 4 series cards.
I'd reccomend some trial and error to get where you are comfortable with the balance between noise and temps. Every card is different after all
