Please note that a BIOS upgrade utility provided by your board manufacturer - might be upgrading more things than just a BIOS. For example: EC firmware for a controller which i.e. may be adjusting the fan speeds depending on a temperature. As you see, simply upgrading a BIOS via flashrom may leave you with the old version of EC firmware, which could be undesirable.
