2X Copper PCB
SMART FAN 6
1. Fully Covered Thermal Design
High coverage MOSFET and integrated molding Heatsinks to improve thermal efficiency with better airflow and heat exchange.
2. 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.
3. 2X Copper PCB
2X Copper PCBs design effectively lower the component temperature by its high thermal conductivity and low impedance.
1. 2X Large Surface
Increased surface area up to 2X larger compared to traditional heatsinks. It improves heat dissipation from the MOSFETs.
2. 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.
3. 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.
Thermal Throttling As Temperature Rises
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.
