My system shows a CPU temp of 39C and a chassis temp of 35C. This is with 1 front case fan, 1 rear case fan, a HDD Cooler (with 2 tiny fans in the front), the Enermax 431W dual fan PSU, and Artic Silver III and a Volcano 7+ on my AMD XP 2000+ CPU. And it is all housed within a Funai (?) Aluminum case with the plexiglass side window from Fry's. Maybe this is important, too: I have the BLUE neon light inside!
I just checked it again, and it's exactly the same. I burned it in starting about a week ago, and I only have the Volcano 7+ running at MEDIUM speed now (pretty dang quiet!)
