  * CPU VRM Temperature measurements under system setup with water-cooler block and CPU running at 100% loading

Doubling the amount of copper provides a more effective thermal cooling solution by delivering a more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. In fact, GIGABYTE Ultra Durable 3 motherboards are able to deliver up to 50°C cooler working temperatures than traditional motherboards*.

Lower RDS(on) MOSFETs
‧ Optimized gate charge to minimize switching losses.
‧ Lower temperature, smaller size, better thermal characteristics.
For the MOSFETs, GIGABYTE decided to uses Low RDS(on) MOSFETs. These are MOSFETs that are specially designed to produce lower switching for faster electric current charging and discharging. The benefits of using these more expensive components is that Low RDS(on) MOSFETs have lower power consumption during the switching process, resulting in a faster switching process and less heat generation.
What is a MOSFET?
A MOSFET is a switch that allows or disallows electric current to pass through an electronic circuit.
Lower RDS(on) MOSFET
  16% Lower
Standard MOSFET      
In fact, when compared to standard MOSFETs, RDS(on) MOSFETs temperatures are 16% lower.
    Lower Resistance = Lower Power Consumption = Lower Heat  
  Power Consumption
Heat is a by-product
of power consumption
Power Equation: P = I 2 x R
(P: Power, I : Current, R: Resistance)
