I reviewed your post and I understand that you are getting system fan 90B error.


Don’t worry, I assure you I will try my best to get this sorted.       


What is the exact model of your computer?

What is the operating system you are using?

When was the last time the computer was working fine?

Have you made any software or hardware changes on the computer?


While you respond to that, I recommend you update the BIOS on the computer from the below link and check whether the issue is resolved.


Let me know how it goes and you have a great day!
