thanks for the reply
well in the bios the default protection settings were at 100c for all. in pc probe by default the MB Threshold is set to: 65c, NB: 80 and SB: 55. I kept getting warnings that the SB was hitting 55c so I upped it to 60c cos it was doing my head in.
Ive always found pc probe default settings to be a bit dodgey with past asus boards so dont go on them much. The bios settings of 100c seem a bit stupid to. I wish asus would just tell you on their website like amd do for their cpu's. Is 60c really high for the SB though?? I dont want to destroy my board as I only bought it a couple weeks ago n paid quite a wad of cash for it!
