I recently purchased a PC equipped with a Z790 MSI Pro-A and accidentally missed installing PWM fans. The motherboard includes a "digital PWM" setting, which seems intended for non-PWM fans, though I can't locate its purpose or usage. It's not a major concern since I didn’t expect to adjust the fan curve, but understanding this feature would be helpful.

Digital PWM refers to the power distribution method, not the fan adjustment.

Verify your fan headers support DC mode within the BIOS settings, enabling fan curve adjustments.
