Vostro 3525 caught smoke while updating firmware

Hello.

Another question here. I was updating my firmware some time ago, and almost got my CPU burned. Turns out, when system reboots to flash firmware it keeps fans on bare minimum, and while firmware flashes they speed is not adjusted. So by the time firmware update ended the visible smoke was going out through vent. Then my system rebooted and fans kick in. Can this be fixed somehow?

Also I have a weird feeling firmware update doesn't work with BitLocker, it only happened when I temporary opened my drive.

Thanks in advance!
