Fan Control

This is the release repository for Fan Control, a focused and highly customizable fan controlling software for Windows.

Main features

• Guided setup process on first launch
• Save, edit and load multiple profiles
• Change the theme and color to fit your setup
• Multiple temperature sources ( CPU, GPU, motherboard, hard drives... )
• Multiple fan curve functions, including a custom graph
• Mix fan curves or sensor togethers (max, min, average)
• Low resource usage
• Advanced tuning with steps, start %, stop %, response time and hysteresis

New

• (NEW) Opt-out of update popup for a specific version
• Configurable temperature range for graphs
• Decimal support in graphs
• Nickname any temperature sensor from the sensor settings dialog
• Auto fan curve (BETA): Automatically adjust speed to keep target temperature

Installation

1. Download the latest archive
2. Extract to the desired installation folder
3. Start FanControl.exe
4. (Optional) -c or --config [json config file] command line arg

Plugins

The plugin system let you inject any type of sensor into FanControl, see Plugins wiki

Some examples (notify me if I'm missing some):

• (NEW) https://github.com/iJacks1980/FanControl.CommanderPRO to interface with Corsair commander devices
• (NEW) https://github.com/medevil84/FanControl.AquacomputerHighFlowNext to interface with aquacomputer HighFlowNext
• https://github.com/Rem0o/FanControl.HWInfo to import HWInfo sensor data
• https://github.com/Rem0o/FanControl.DellPlugin for dell laptops and some towers

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:

  • https://github.com/LibreHardwareMonitor/LibreHardwareMonitor
  • https://github.com/falahati/NvAPIWrapper

• Please only open issues for the software itself, UI, feature request and so on.

• If you do have a 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 in there, 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: 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.

Fan curve types

• (NEW) Auto: PI controller-ish type function. % will surf until temp is stable at load.
• Linear : Temperature based linear function
• Graph : Temperature based custom curve
• Target: Temperature based that holds speed until target temperature is reached
• Mix : Use two different curves and apply a mix function (Min, Max, Sum, Average, Subtract)
• Sync : Sync to an existing control
• Flat: Set a fixed %

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
