Hi, Just wondering if anyone else was caught out the first time they installed an AMD Athlon 64 CPU in a Cool 'n Quiet capable mobo ? I'd never seen it in action before and it took me totally by surprise when the CPU fan turned itself off - I yanked the power cable out ASAP :-) I then did a bit of Googling only to find that this behaviour is by design - doh ! Then checked the temps in the BIOS and sure enough, as soon as the CPU hit 34c the fan kicked back in - phew :-) Had me worried for a while there I can tell you ! -- Cheers, *Paul* All general statements are false.
