The logo on my DeepCool AK400 Digital Pro stays illuminated even when the computer is shut down. Turning off the display in the cooler's software does not disable the logo, and the light only goes out when I switch off the power supply. Other RGB components—and even the cooler's side strips—shut down normally. Is there another setting, cable, or motherboard control that can disable the logo separately?

Check whether the cooler’s software has a separate logo-light control; disabling the display may only turn off the temperature readout. Since the AK400 Digital Pro also uses an ARGB connection, try controlling that through your motherboard’s RGB software. It would also help to confirm whether any other lighting remains on during shutdown.

The software only provides an option to disable the display. My other RGB components turn off with the PC, and the cooler’s small RGB strips shut down too—the logo is the only light that stays on.
