A status and control utility that iteracts with CorsairLink products
OpenCorsairLink is a command-line tool to monitor and control the fan speed,
LED colour and pump volumes of specific Corsair power supplies and cooling solutions.
To allow this snap access to your device(s), issue the following connection commands:
Examples:
To set your own custom fan curve for a specific set of temperatures, use the following command:
To set LED colors and mode:
To set pump cooling mode:
OpenCorsairLink is unofficial and is not endorsed or affiliated with Corsair.
General options:
- --help: prints this message
- --version: displays version
- --debug: displays enhanced Debug Messages
- --dump: implies --debug, dumps the raw data received from the device.
- --machine: prints status in a machine readable format
- --device <Device Number> : specify selected device
- --led: control LED modes alongside standard, error and warning colors
----fan: set fan mode and create speed profiles
---pump: set pump cooling mode
LED (--led) options: (after specifying a device):
channel=N,mode=N,colors=HHHHHH:HHHHHH:HHHHHH,temps=TEMP:TEMP:TEMP
- channel= <led number> : selects LED channel to configure. Accepted values are 1 or 2.
- mode=:
- 0: static
- 1: blink (Only Commander Pro and Asetek Pro)
- 2: color Pulse (Only Commander Pro and Asetek Pro)
- 3: color Shift (Only Commander Pro and Asetek Pro)
- 4: rainbow (Only Commander Pro and Asetek Pro)
- 5: temperature (Only Commander Pro, Asetek, and Asetek Pro)
- Colors: <HTML Color Code>, defines the LED color
- Warn: <HTML Color Code>, defined the warning LED color
- Temps: <Temperature in Celsius>, defines the warning temperature LED color
Fan (--fan) options: (after specifying a device):
channel=N,mode=N,pwm=PWM,rpm=RPM,temps=TEMP:TEMP:TEMP,speeds=SPEED:SPEED:SPEED
- channel= <fan number>: selects a fan to setup. Accepted values are 1, 2, 3 or 4.
-mode=:
- 0: fixed PWM (requires the PWM to be specified)
- 1: fixed RPM (requires the RPM to be specified)
- 2: default
- 3: quiet
- 4: balanced
- 5: performance
- 6: custom Curve
- PWM <PWM Percent>: the desired PWM for the selected fan. NOTE: only with fixed PWM
- RPM <fan RPM>: the desired RPM for the selected fan. NOTE: with fixed RPM
- For Custom Curves:
- Temps <C>: define Celcius temperatures for fan
- Speeds <Percentage>: define RPM percentages for fan
Pump (--pump) options: (after specifying a device):
-mode=:
- 0: quiet
- 1: balanced
- 2: performance
Without options, OpenCorsairLink will show the status of any detected Corsair Link device.
