It comes as no surprise at all as we climb up in speed and the voltage on our CPU, the increased heat jumps up. Even at 5.35GHz, though, the idle temperature is extremely good on the MSI Z68A-GD80.
One of the biggest reasons for the big increase in temperature at 5.35GHz, though, would have to be the small amount of droop on offer from the MSI board. With our CPU voltage set to 1.5v in the BIOS the reported numbers under load were 1.47v, which is extremely strong when compared to the ASRock which drooped down to 1.41v.
Power Draw Tests
As we pump more and more volts through our system to achieve a huge overclock, you can see the power draw does indeed climb. The numbers aren't out of the ordinary, though, and really for a setup like what we've got today a strong power supply like the AX750 from Corsair would be perfect as it gives you headroom for another video card later down the track.
