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. |
