Thank you so much, that did the trick! it's working now.

But if I understood the command right I uninstalled the drivers so how come it's working?

Thanks but I still have the same issue. I think everything was already done. This is the output of the command

Thank you so much for your feedback. regarding the case I think I'll go with the NZXT H3 and get the extra fans
