19 liquidctl is a utility for overseeing and controlling some hardware
20 monitoring devices not yet supported at the kernel level. Because liq‐
21 uidctl directly accesses the hardware devices, root privileges are gen‐
22 erally required, though this can be avoided with appropriate udev
23 rules.
24 liquidctl list outputs all compatible devices found on the system. In
26 case more than one device is found, the desired one can be selected for
27 later invocations with --match=substring, where substring matches part
28 of the desired device's description using a case insensitive compari‐
29 son.
30 liquidctl list --verbose enables the display of additional identifiers
32 and addresses that can also be used to select specific devices. These
33 can be better suited for certain use cases, such as non-interactive
34 scripts.
35 liquidctl initialize prepares a device for later commands. Most
37 devices must be initialized after every boot. Unless finer control is
38 required, all devices can be initialized at once with liquidctl ini‐
39 tialize all. Some devices may output some information at this stage.
40 liquidctl status displays the status of all devices that match the pro‐
42 vided filtering options.
43 liquidctl set channel speed allows the user to set fan and pump speeds.
45 These, depending on the device, can be set to fixed duty values, vari‐
46 able temperature\[u2013]duty curves, or both.
47 liquidctl set channel color allows the user to configure and set light‐
49 ing modes. Each color is specified in hexadecimal RGB, without pre‐
50 fixes (e.g. ff2608). Supported modes and additional options vary by
51 device and are listed in later sections of this manual.

54 Device selection options
55 Devices can be selected using one or more values taken from list --ver‐
56 bose.

60 tion.

91 --speed=value
93 Abstract animation speed (device/mode specific).
94 --time-per-color=value
96 Time to wait on each color (seconds).

118 Use Asetek 690LC in legacy mode (old Krakens).
119 --single-12v-ocp
121 Enable single rail +12V OCP.
122 --version
124 Display the version number.
125 --help Show the embedded help.

157 The rainbow mode speed can be configured with --speed=[1–6]. The speed
159 of the other modes is instead customized with --time-per-color (fad‐
160 ing and blinking) and --time-off (blinking only).
161 All modes except blackout support a visual high-temperature alert con‐
163 figured with --alert-threshold and --alert-color.

168 but requires --legacy-690lc to be passed on all invocations.

204 Setting a fixed fan speed changes the fan mode to software control. To
206 revert back to hardware control, run initialize again.
207 (Experimental feature) The +12V rails normally function in multiple-
209 rail mode. Single-rail mode can be selected by passing --sin‐
210 gle-12v-ocp to initialize. To revert back to multiple-rail mode, run
211 initialize again without that flag.
