Thanks for your response. I'm hoping it's just a chassis alarm for a case fan. It looks like my chassis has that capability. I only have a single CPU 12 disk box with a 750w (I believe) PSU so I think it's not overloaded. Also the alarm came on at idle. I'm waiting for the next occurrence to see if I can diagnose further. -D
