Thanks for replies;
Diego_Intel: I have seen the specs where the temp limt runs around 80c ( did not commit it to memory if this is a little off) The initial warning begins @ 58c. This is the beginning and where no matter what application is open, the warning interrupts its operation. I have seen the temp as high as 65c, since I don't want to be the blame in frying my board this is where I closed all apps and placed two box fans by the pc to help cool it.
spearson: Yes it is the IDU. The message does state "SIO", not the other.
Hope this added data helps.
