⚖️ Overlay Profiles

Overlay Profiles modify a base Profile’s output by applying offsets. Use them to tailor behavior for specific fan groups, RPM ranges, or airflow needs—without duplicating the base Profile.

Types

Static Offset

Apply a fixed offset (positive or negative) to a Profile’s output. Useful to:

• Adjust case pressure across front/rear fan groups
• Fine‑tune a group’s output relative to the base profile

Graph Offset

Apply a curve-based offset to a Profile's output. While more flexible than a static offset, it unlocks powerful use cases:

• Scale the base Profile's output by a percentage
  (20% of the base Profile's output)

• Apply different offsets for different fan RPM and duty ranges
  

• Compensate for different fan makes/models (align airflow and perceived noise)
  

• Apply a start speed to avoid stall at low duties
  (Starts spinning at 30%)

• Apply a stop speed for semi‑passive operation (Stops spinning at <20%)

• Invert a Profile's output to compensate for internal airflow
  

• Turn a fan off beyond a threshold (e.g., when other case fans are already working hard)
  (Stops spinning at >40%)
