1. Connector RT1: A blue thermal resistor is already soldered to
connector RT1 so as to sense the temperature round the mainboad.
What RT1 does is to transmit the thermal signal to BIOS or Hardware
Monitor.
2. Connector RT2: A thermal cable is needed to connect RT2 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 mainboard RT2 header, 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.
