    You can't roll back to previous version of BIOS. Downgrading the BIOS is not something people normally do, but there are times when the older BIOS version works better than the newer/current one and you need to downgrade to it while waiting for a newer, more stable BIOS release.

    You may try to reset BIOS to default settings and check the fan issue.
    Access the BIOS Setup utility. 
    Press the F9 key to automatically load the factory default settings. 
    Confirm the changes by highlighting OK, then press Enter.
    To save the changes and exit the BIOS Setup utility, press the F10 key.
