Hey guys,

Does anyone know how to turn off the USB header standby power in BIOS?

My Kraken CPU cooler RGB does not turn off after shutdown, drives me nuts

I'm running a z490 pro4.

Thanks in advance.

Dear Jackaryy49,

Thank you for posting your query to the ASRock forum.

Regarding your question, kindly disable the following settings in the BIOS.
Advanced\Chipset Configuration\Turn On Onboard LED in S5

With thanks,

Thanks for your prompt reply,

I checked the setting in the BIOS that you stated and it was already disabled.

Is there something else in should be looking at?

Dear Jackaryy49,

Thanks for the reply.

Does the Kraken fan use the USB 2.0 header? If yes, please try to enable the deep sleep function as below:
