Once into the H/W Monitor section, you can see the temperature monitors across the
top. Below the monitors are the two PWM fans with SMART controls: CPU_FAN and
CHA_FAN. Each fan is set to “Smart,” which means the PWM controller uses a Smart
curve for fan controls. 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;
the stall speed will vary from fan to fan.
Note:
If using an AIO CPU liquid cooler, such as the EVGA CLC Coolers, it is
recommended to connect this to a CPU header, and set the speed to MAX. If
left on SMART or lower than MAX, the cooler may not be recognized properly
by the operating system or its software may not function properly.
Below the fans, you will see the remaining PWM fan: SYS_FAN. This fan can only be
set to a static speed percentage. Again, if you set the speed too low, however, the fan
may stall. The stall speed will vary from fan to fan.
The B360 Micro Gaming fan controller auto-detects whether each fan connected to the
PWM headers are controlled by DC or PWM, and sets the control mode accordingly.
DC fans are still supported, but are controlled entirely by reducing the amount of
current provided to the fan based on the static percentage set in the BIOS plus the fan’s
maximum speed and power. PWM fans are controlled by a PWM signal, which
constantly pulses speed instructions to the fan based on the static percentage set in the
BIOS and the fan’s maximum speed; this permits the fan to run with sufficient power -
even at low speeds - to avoid a stall. Fans utilizing a PWM header can still be controlled
via PWM signals, even if the fan is powered by a different connector, such as a molex,
SATA, or 3-pin power connector not directly connected to the motherboard.
Note:
If you do not attach a fan prior to power on, the fan may run at 100% or
behave erratically, regardless of the static percentage set in BIOS.
