@Den-78 I would open a ticket with F5 TAC for this issue.

Hi @Den-78 ,

As @Den-78 mentioned, you have to open a support case in the web portal

Just take in mind that version 11.6 is not supported by F5

So if they request a qkview they going to decline your case and is necessary to upgrade your F5 system, you can find info of how to upgrade your system:

Hope it´s works.

Hi!  Sebastiansierra

I don't think its hardware problems or os bug, fresh install (last for contract) and in test 17.1 )) = same results, all fan at 12K RPM ... (((( In EDU = all hardware test pass, and fan report as in os = 12K ...

I think its "bug" in AOM firmware, now its last 4.08 as i can see 

2 same systems have this problem 

May be some way to control fan ?
