From reading Sun documentation after an E3000's started screaming because
the air conditioning failed, if I remember correctly, you get two reasons
to scream - if the limit is reached, or if it stays at the "hysteresis"
point for a long time. I'm not quite sure what the "long time" is,

As I remember, the bios reported 50C...must check...
