Issues and hardware compatibility

  • I am not the main developer for the driver/backend portion of this software. Fan Control is basically a UI on top of existing hardware libraries. Any issue regarding hardware compatibility entirely depends on the following projects. If you can't contribute meaningfully with a branch/PR, don't pollute their issue page with "XXXXX doesn't work". The hardware is needed for testing. If a dev has interest in that project, is browsing it, has your specific hardware AND the knowledge to make it work, that dev won't be looking for your issue, he'll just raise a PR.

  • Please only open issues on this repository for the software itself, UI, feature request and so on. If it's a "make this work please" hardware support request, I will link this section of the README and close your issue.

  • If you do have a special hardware compatibility request and you can provide a working sample of code that can be used in .NET, like with a Plugin, then feel free to submit that.

FAQ

  • Q: What settings should I set in my BIOS to play along nicely with FanControl?
    A: You want to avoid any "smart" control from your BIOS. Setting a fixed default speed, like 50%, works great for most people. Also keep an eye if your BIOS has PWM or DC mode on. One could work better for you depending on your setup.
  • Q: My Nvidia cards has X fans, but only two cards show up, why?
    A: Your card only has 2 channels, more than 1 fan are plugged to the same channel.
  • Q: My Nvidia cards won't go below 30% and doesn't go to 0 RPM, why?
    A: See here
  • Q: My new AMD card can't be controlled, why?
    A: Newer AMD cards are not supported. If you can provide a working sample of code that works with these newer cards, please share!
  • Q: There is no control cards / control cards are missing / control cards are not changing my fan speeds, what's the issue?
    A: See Issues and hardware compatibility.
  • Q: How does [FAN CURVE TYPE] works and what does its parameters do?
    A: Click on its card's icon at the top left, a dialog will tell you.
  • Q: Does it run on my OS?
    A: If your OS is Windows 10 Or 11, yes.

Graph fan curve editor

  • (NEW) Change the temperature range for finer control over a small range
  • Add, remove and drag points arround the graph
  • Copy and paste points from a graph to another
  • Fine-tune the response with the hysteresis and response time parameters
