Motherboard monitor does not change any settings. If you do get MBM, get the latest version 5.1. Normal temperatures for a Tbird is around 40-50C using the SocketA Thermister reading. However, you cannot accurately see the exact temperature or when the CPU overheats(takes only a second to crash the comp). Since the thermister is located in the socket, below the CPU, its heatpathway would not immediately tell you the temperature of the CPU core the moment it overheats.
