Hi,
I have an S1200KP based system that has suddenly started running its fans at full speed. 
It seem sto happen in conjunction with me reseting the fans configuration to default in the BIOS, but I have since noted the PCH temp is 0
I have an identical system sat next to it with nice quiet fans and that is showing a PCH temp.....
Could I have a board gone faulty or is there some other config I should be looking at...
Thanks!!
