CPU Thermal Protection
Aimed to prevent the CPU from overheating, MSI has developed a CPU
Thermal Protection mechanism for AMD Athlon XP CPU platform. This CPU
Thermal Protection mechanism works on a thermal signal sensor. If the mecha-
nism senses an abnormal temperature rise, it will automatically shut down the
system and the CPU temperature will then drop down and resume normal. With
this unique feature, users can better protect their CPU. Please note that this
feature is for AMD Athlon XP CPU only.
