EVGA Z790 CLASSIFIED (121-RL-E798)
Once into the H/W Monitor section, you can see the temperature monitors across the
top. Below the monitors, each fan is already configured in Smart mode, which means the
fan controller is using a Smart curve for fan controls. Each fan can be set to a separate
fan curve. To set a Smart curve, please see the guide starting at the top of the next page.
The +/- buttons next to Smart allow you to set your fans at a static speed percentage,
instead of a curve. If you set the speed too low, however, the fan may stall.
Below the PWM fans, you will see the six (6) PWM/DC fans: CHA_FAN, SYS_FAN,
PWR_FAN, AUX_FAN, and PUMP1 and PUMP2. The fan controller will
automatically detect and set the fan to either PWM or DC.
Alternatively, the PWM/DC fan headers can be set to either DC Mode or PWM Mode,
which can be selected by clicking on the pulldown menu. DC Mode powers the fan
directly by +12V voltage, while PWM Mode powers a PWM fan via pulse.
PWM mode is necessary if you are running a PWM fan powered by a different
connector, such as a molex, SATA, or 3-pin header not on the motherboard. If you
don't select PWM mode in this scenario, the fan may run at 100%, or behave erratically,
regardless of the Smart Profile or percentage that you set above.
