1-6.2 Thermal Resistor and Connector
1. Resistor RT1: A thermal resistor is
mounted by default to connector RT1 so
as to detect the external CPU temperature
. What RT1 does is to transmit the thermal
signal to Hardware Monitor.
RT1
RT1 is mounted with Ther-
mal Resistor by default for
detecting the external CPU
temperature.
2. Connector Jp7: A thermal cable is needed
to connect Jp7 to on-board devices such
as HDD, Graphics card etc., so as to
detect the temperature generated therein.
Please connect the end (a) of the thermal
cable to Jp7, and tape another end (b) of
thermal cable on to the device which you
want to monitor. After you have finished
the thermal cable installation, you will see
the detected temperature in BIOS setup
or Hardware Monitor utility.
