3. HARDWARE SETUP 3.6.8 Precautions Operating a processor at temperatures above its maximum specified operating temperature will shorten the processor lifetime and may cause unreliable operation. To prevent system overheat and/or damage, it is important to have accurate temperature readings of the processor core (the main source of power dissipation) for system thermal management. Included inside Pentium III, Pentium II (Deschutes), FCPGA370 Celeron, and PPGA370 Celeron processors is a thermal sensor that is connected to the internal thermal diode. Unlike other motherboards, this motherboard was designed to acquire thermal data directly from the processor thermal diode. Therefore, the CPU temperature reported may be higher than those from motherboards that take readings from thermal sensors external to the processor. This is not a cause for alarm. If, however, the BIOS and/or your hardware monitoring program is reporting a CPU temperature above the threshold, check the following: 1. An Intel recommended fan heatsink is used. 2. Good quality thermal interface material is used. 3. The heatsink is correctly installed onto the processor with a strong retention clip. 4. There is no visible gap between the processor die and heatsink. The thermal interface material should be continuous with no through-holes or debris.

3.6.8 Precautions
Operating a processor at temperatures above its maximum specified operating tem-
perature will shorten the processor lifetime and may cause unreliable operation. To
prevent system overheat and/or damage, it is important to have accurate tempera-
ture readings of the processor core (the main source of power dissipation) for sys-
tem thermal management. Included inside Pentium III, Pentium II (Deschutes), FC-
PGA370 Celeron, and PPGA370 Celeron processors is a thermal sensor that is con-
nected to the internal thermal diode.
Unlike other motherboards, this motherboard was designed to acquire thermal data
directly from the processor thermal diode. Therefore, the CPU temperature reported
may be higher than those from motherboards that take readings from thermal sen-
sors external to the processor. This is not a cause for alarm. If, however, the BIOS
and/or your hardware monitoring program is reporting a CPU temperature above
the threshold, check the following:
1.
An Intel recommended fan heatsink is used.
2.
Good quality thermal interface material is used.
3.
The heatsink is correctly installed onto the processor with a strong retention clip.
4.
There is no visible gap between the processor die and heatsink.
