Download Fan Control for Windows

• Operating system: Windows 11 or Windows 10, 64-bit.
• Runtime: .NET 8 Desktop Runtime for the modern edition, or .NET Framework 4.8 (already included in current Windows builds) for the Framework edition.
• Permissions: an administrator account, because the sensor driver needs elevated access.
• Hardware: a motherboard or GPU supported by LibreHardwareMonitor. Most desktop boards from the last decade qualify; laptops are hit-and-miss, see the laptop guide.

Fan Control is Windows-only. There is no macOS or Linux build, and none is planned by the developer.

Each release includes a portable archive and an installer for both runtimes. The portable ZIP is a single folder you can drop anywhere, which suits users who like to keep tools on a secondary drive or run them from a USB stick. The installer registers the app in Windows, creates shortcuts and can download the runtime for you, and it is the better pick for most people setting up a single PC. Both editions are functionally identical.

The exact version number changes with every release; the Download button on the home page reads it live from GitHub, and the release page lists the full changelog for each build. We deliberately do not print a version here so this page never shows an outdated number.

1. Download the archive or installer from the release page and, for the ZIP, extract it to a folder such as C:\Tools\FanControl.
2. Start FanControl.exe. Windows SmartScreen may warn about an unrecognized app on first run because the build is not signed with a commercial certificate; choose More info, then Run anyway.
3. Approve the User Account Control prompt.
4. Follow the assisted setup to pair fans with speed sensors, then let calibration run on each fan you plan to control.
5. Assign a fan curve to each control card, save, and turn on Start with Windows if you want the profile applied automatically.

A working setup has three parts: a temperature source, a fan curve that maps temperature to speed, and a control that applies the curve to a physical fan. Start simple, one Linear curve for the CPU fans and one for the GPU, then refine. Case fans usually benefit from a Mix curve that watches both CPU and GPU so they speed up for whichever component is hot. The PWM fan control guide covers curve design for case airflow, and the documentation lists every parameter.

• App opens but shows no controls: close vendor fan utilities, reboot, and run as administrator.
• A fan runs at 100% regardless of the curve: the BIOS header mode does not match the fan type, or the fan is not PWM-capable.
• GPU fan ignores low percentages: expected; GPU drivers enforce a minimum around 30%. See GPU fan control.
• Settings reset after reboot: confirm the configuration was saved and that Start with Windows points at the right config file.
