• Maximize full multi-cores performance

Thermal

Thermal Design

• M.2 Thermal Guard
  The M.2 Thermal Guard prevents throttling and bottlenecks from high speed M.2 SSDs as it helps to dissipate heat before it becomes an issue.
• Fully Covered Thermal Design
  High coverage MOSFET and integrated moulding Heatsinks to improve thermal efficiency with better airflow and heat exchange.
• 2X Copper PCB
  2X Copper PCBs design effectively lower the component temperature by its high thermal conductivity and low impedance.

Fully Covered MOSFET Heatsink

• 2X Large Surface
  Increased surface area up to 2X larger compared to traditional heatsinks. It improves heat dissipation from the MOSFETs.
• Real One-Piece Build
  TMOS is a TRUE single piece heatsink. Its one-piece design and larger surface drastically improve the cooling performance against competitors’ multi-piece design.
• Multi-Cut Design
  TMOS features several channels and inlets on the heatsink. This design allows for the air flow to go through which leads to a great improvement of the heat transfer performance.

M.2 Thermal Guard

With durability in mind, GIGABYTE provides a thermal solution for M.2 SSD devices. The M.2 Thermal Guard prevents throttling and bottlenecks from high speed M.2 SSDs as it helps to dissipate heat before it becomes an issue.

2X Copper PCB

• 3% Cooler by implementing
• 2x copper PCB Design

By adopting 2x copper on PCB inner layer, it lowers the components' temperature at least 3% by turning the PCB into a super thin PCB size copper heatsink to dissipate the heat from the components effectively, due to it’s high thermal conductivity and lower impedance.

Smart Fan 6

Smart Fan 6 contains several unique cooling features that ensure gaming PC maintain its performance while staying cool and quiet. Multiple fan headers can support PWM/DC fan and pump, and users can easily define each fan curve based on different temperature sensors across the board via intuitive user interface.

Headers & Sensors

• 4 PWM/DC Fan Headers
• 6 Internal Temperature Sensors

Cooling Features
