D.6 Thermocouple Wire Management
When installing the processor into the socket, the thermocouple wire should route
under the socket lid, as Figure 7-37. This will keep the wire from getting damaged or
pinched when removing and installing the heatsink.
Note: When thermocouple wires are damaged, the resulting reading maybe wrong. For
example, if there are any cuts into the wires insulation where the wires are pinched
between the heatsink and the socket lid when installing the heatsink, the
thermocouple wires can get in contact at this location. In that case, the reported
temperature would be the point of the heatsink/socket lid 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.
