optiplex-fan-control

Project information

The Hardware Problem: Dell OptiPlex BIOS often uses a "step-function" fan curve that remains silent until thermal throttling occurs, possibly never reaching full speed, or jumps to 100% RPM instantly even under no load.

The Software Fix: This package provides a compiled C daemon that implements a smooth, linear ramp based on real-time CPU Package temperatures. It includes a bypass tool to disable onboard Dell BIOS fan management during operation and restores it gracefully on shutdown via systemd.

Daemon and package code written with the grateful assistance of Gemini.
