title: The Maxim MAX31790 Fan Controller
maintainers:
- Guenter Roeck <linux@roeck-us.net>
- Chanh Nguyen <chanh@os.amperecomputing.com>
description: >
The MAX31790 controls the speeds of up to six fans using six
independent PWM outputs. The desired fan speeds (or PWM duty cycles)
are written through the I2C interface.

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
