How do I control the fan on my framework?

[LovelyA72]

I read that there is fanduty and autofanctrl command that I can use to control my fan speed. How can I do that on Windows?

Right now there's no easy way to do this.

With the test tool from this distribution, FauxECTool, you can sort of accomplish it with raw commands (as fauxectool doesn't support symbolic commands 😄)

Set fan 0 duty% to 0x00000064, or 100%

fauxectool 0x24 d64

0x24 is EC_CMD_PWM_SET_FAN_DUTY

Note: there is no way to specify the percentage in decimal

Set fan 0 RPM target to 4000 (0x00000FA0) directly

fauxectool 0x21 dFA0

0x21 is EC_CMD_PWM_SET_FAN_TARGET_RPM

Note: there is no way to specify the RPM in decimal

Note: the fans on this board operate up to 6800 RPM

Restore fan 0x00 to automatic thermal control

fauxectool 0x52 b0

0x52 is EC_CMD_THERMAL_AUTO_FAN_CTRL

I've been testing a build of ectool (the Linux version) that works on Windows, which should make this much easier. It is not yet ready for release.

I've got good news! I brought the upstream ectool code out into a separate repository and ported it to Windows.

Builds are available over there. Just check out the latest windows/x64 artifacts:
