The first thng to consider, for socket-a setups, is where the temp is being measured from, and what bios revision you have?
SEcondly, I would be vary wary of using a c-orb for a 1.1ghz CPU. The way air flows off the c-orb forces air underneath the socket, which interferes with socket-thermistor temp readings. Chances could be very likely that your c-orb equipped t-bird is running some 30-32C over ambient case temp(CORE temp wise).
What is your ambient case temp? And what is your MB temp?
