I have a MSI KN1 extreme lite motherboard with a nvidia chipset. The
northbridge chipset has begun to climb to 180 degrees Fahrenheit (82
degrees Celsius) The temperature will stay there for a very short (one
minute) time and drop back to 60 degrees Celsius. This is at idle. There is
a 40 mm fan mounted on the chipset heatsink, and I cleaned the heatsink and
chipset and put new thermal compound between them. This behavior just
started about two weeks ago, the computer is three years old. This is a
real temperature increase, you can feel a rise in the heat coming from the
case fans. There is a power supply fan and a 80 mm case fan drawing air out
the the case.
Any ideas as to what the problem might be?
How long is the motherboard likely to last at this temperature?
Thanks, Terry
