    At the UEFI screen, press F9, then F10 to get back to the default settings.

    I have tried this. But everything is still the same. The bios version is still 1.47, the fan is still howling whenever i open any app and the cpu temp is still around 60o even when i just leave my laptop there and don't do anything :(

    Double check the version you wish for downgrading. Perhaps it is different for your SNID,

    Hmm, when i upgrade bios to 1.47, the boost screen said My current version are 1.45. And when i installed 1.43, it didn't let me to do that. So i wonder maybe i should find version 1.45?

    When you entered your SNID on the driver download page; which version was available, 1.43 or 1.45?
    If only 1.43  appeared & you are unable to install it per Sharanji's post, it is possible to go to the motherboard manufacturer's website to look for 1.45. 
    It may be safer to back everything up & do a factory reset, rather than to risk bricking the device.
