Several products are available that are based on the same Asetek 690LC base design:
- Current models:
- EVGA CLC 120 (CLC12), 240, 280 and 360
- Corsair H80i v2, H100i v2 and H115i
- Corsair H80i GT, H100i GTX and H110i GTX
- Legacy designs:
- NZXT Kraken X40, X60, X31, X41, X51 and X61
Note: a different kernel driver is necessary on Windows (see: Installing on Windows).
Note: when dealing with legacy Krakens the --legacy-690lc
flag should be supplied on all invocations of liquidctl.
All 690LC devices must be initialized sometime after the system boots. Only then it will be possible to query the device status and perform other operations.
# liquidctl initialize
Similarly to other AIOs, the cooler can report fan and pump speeds as well as the liquid temperature.
# liquidctl status
Asetek 690LC (assuming EVGA CLC)
├── Liquid temperature 28.7 °C
├── Fan speed 480 rpm
├── Pump speed 1890 rpm
└── Firmware version 2.10.0.0
Fan speeds can be configured either to fixed duty values or profiles. The profiles accept up to six (liquid temperature, duty) points, and are interpolated by the device.
# liquidctl set fan speed 50
# liquidctl set fan speed 20 0 40 100
Note: fan speed profiles are only supported on non-legacy models.
Pump speeds, on the other hand, only accept fixed duty values.
# liquidctl set pump speed 75
There's a single lighting channel logo
. The first light mode – 'rainbow' – supports an abstract --speed
parameter, varying from 1 to 6.
# liquidctl set logo color rainbow
# liquidctl set logo color rainbow --speed 1
# liquidctl set logo color rainbow --speed 6
Note: the 'rainbow' lighting mode is currently only supported by EVGA units.
The 'fading' mode supports specifying the --time-per-color
in seconds. The defaults are 1 and 5 seconds per color, for modern and legacy coolers respectively.
# liquidctl set logo color fading ff8000 00ff80
# liquidctl set logo color fading ff8000 00ff80 --time-per-color 2
The 'blinking' mode accepts both --time-per-color
and --time-off
(also in seconds). The default is 1 second for each, and whenever unspecified --time-off
will equal --time-per-color
.
# liquidctl set logo color blinking 8000ff
# liquidctl set logo color blinking 8000ff --time-off 2
# liquidctl set logo color blinking 8000ff --time-per-color 2
# liquidctl set logo color blinking 8000ff --time-per-color 2 --time-off 1
The coolers support two more lighting modes: 'fixed' and 'blackout'. The latter is the only one to completely turn off the LED; however, it also inhibits the visual high-temperature alert.
# liquidctl set logo color fixed 00ff00
# liquidctl set logo color blackout
It is possible to configure the visual alert for high liquid temperatures:
--alert-threshold <number>
: set the threshold temperature in Celsius for a visual alert
--alert-color <color>
: set the color used by the visual high temperature alert
Note that, regardless of the use of these options, alerts are always enabled (unless suppressed by the 'blackout' mode): the default threshold and color are, respectively, 45°C and red.
