• HID PSU:
  • Replaces the fan minimum duty with a user-customizable zero-RPM duty threshold.
• Flex PSU:
  • Replaces the fan minimum duty with a user-customizable zero-RPM duty threshold.

PSU Zero-RPM Duty Threshold

When the fan power drops below the threshold, control of the fan will be returned to the PSU allowing zero-RPM operation. When the fan power is at or above the threshold, control of the fan will be returned to Fan Control. The default threshold duties are unchanged from the minimum duties used in previous versions. The threshold may instead be customized by setting the FANCONTROL_CORSAIRLINK_PSU_ZERO_RPM_DUTY environment variable to the desired threshold percentage and restarting Fan Control.
