I'm using this proc with its standard fan and heat sink + nanotherm silver xtc on a Gigabyte 8PE667Ultra. Everything is on default setting (Vcore, FSB). The Enlight case that I use has two fans in it. When idles the temp is only 41?C, but under full load (for example when I run Prime95 + 3Dmark) the temp will jump to 60?C . I got this reading from Mbm5, BIOS, & Sisoft Sandra. Is it normal?
