Question to Z390 XI Hero Owners: forced Fan-Speed to 100% when CPU hits 76 Degrees?

6kbyte

To all owners of the Asus ROG Maximus XI Hero (Z390/Socket 1151): can you tell me if Asus again forces 100% fan-speed to the CPU-Fan header as soon the CPU reaches 75/76 degrees? If so, can I prevent this behavior with a custom fan curve in the BIOS (only) without using additional software in the OS (ASUS AI Suite)? Please do not discuss sense or nonsense, I am looking specifically for an answer to this question. I just want to know if Asus furthermore doesn't allow a 100% custom-made fan-curve across all temperatures, especially on this model.

Doesn't anyone here own this board? Perhaps ASUS can answer this question for me?

Maybe ASUS itself or one of the Mods can help me?

Thank you very much, that doesn't help me. Its an old thread from 2017 and they discuss about older motherboards (Z170/Z270). I asked for a specific and new model.

I'm aware. The same answers are applicable here.

Fan Expert in AI Suite 3 has the option to override the default of 75c. Simply check the Critical Temperature box on the fan you wish to override.
