Voltage

Set to Voltage when you use a CPU fan with a 3-pin fan power cable.

PWM

Set to PWM when you use a CPU fan with a 4-pin fan power cable.

Note: In fact, the Voltage option can be used for CPU fans with 3-pin or 4-pin power cables.
However, some 4-pin CPU fan power cables are not designed following Intel 4-Wire fans PWM
control specifications. With such CPU fans, selecting PWM will not effectively reduce the fan
speed.

 QST is enabled.
