D.7 Thermocouple Wire Management
When installing the processor into the socket, make sure that the thermocouple wires exit above
the load plate as shown in
Figure 41. Pinching the thermocouple wires between the load plate and
the IHS will likely damage the wires.
Note: When thermocouple wires are damaged, the resulting reading maybe incorrect. For example, if
there are any cuts into the wires insulation where the wires are pinched between the IHS and the
load plate, the thermocouple wires can get in contact with each other at this location. In that case,
the reported temperature would be at the edge of the IHS/socket load plate area. This temperature
is usually much lower than the temperature at the center of the IHS.
Prior to installing the heatsink, make sure that the thermocouple wires remain below the IHS top
surface, by running a flat blade on top of the IHS for example.
