The GA-Z77X-UP7 board's operating temperatures recorded at both points were above 40 degrees Celsius! This is despite the presence of its new "Thin Fin" heatsink design that makes up its cooling assembly that is linked up by heatpipes from the VRM heatsinks to that of the board's chipset.
The board also tops the rest in terms of power consumption, but this is due to the presence of more voltage regulation components of Gigabyte's new UP7 standards, that include PowIRstage ICs and high-current 60A chokes. Even if you put that aside, the board does have more ICs onboard that provide for the board's full feature list. All this naturally add up to a slightly increased power draw.
