Read this first — it sets expectations before you go looking for a fan curve that might not be adjustable on your machine.

Fan control depends on your motherboard’s chip

Fanture doesn’t talk to fans directly. It goes through the small controller chip on your motherboard (the “Super I/O” chip, on most boards) that actually drives the headers. Whether that chip is one Fanture — via LibreHardwareMonitorLib — can read and write to depends entirely on the board. Most modern desktop boards work. Most laptops and many prebuilt/OEM desktops don’t expose this at all, regardless of what app you try.

If your board isn’t one Fanture can control, the app still runs in monitor-only mode: you’ll see temperatures, just no fan sliders.

GPU fans are a separate story

Your GPU’s fans go through the GPU vendor’s own driver, not the motherboard chip — so they typically work even on a board whose motherboard fan headers don’t. NVIDIA GPUs are supported today; NVIDIA enforces its own minimum duty (usually around 30%) that isn’t something Fanture can override.

Checking your own hardware

Fanture tells you on first run whether the driver it needs (PawnIO) is installed and readable — see Install. That’s the fastest way to know whether the CPU/motherboard path is working at all. If fan headers still don’t show up in the Fans page after that, your board’s chip likely isn’t one this generation of Fanture supports yet.

Reporting a board

If Fanture doesn’t control fans on hardware you’d expect it to, open an issue on the GitHub repository with your motherboard model — that’s how new chips get support.
