TURBO FAN COOLING SYSTEM GIGABYTE turbo fan cooling system is designed for systems that use multiple graphics cards in space restricted chassis. With the vapor chamber direct touch GPU, blower fan and specially shaped exterior, it provides more airflow and better heat dissipation. THE OPTIMIZED AIRFLOW The specially designed exterior increases the intake airflow of the graphics card in a limited space, and then the heat generated by the graphics card is quickly taken out of the entire chassis by the ultra-durable blower fan. VAPOR CHAMBER DIRECT TOUCH Vapor chamber has the best thermal conductivity to transfer the heat rapidly from the GPU to the heat sink. In addition, the heat of the VRAM and the MOSFET is also conducted through the metal patch to the heat sink, and then the heat is taken out of the entire chassis by the blower fan. Double ball bearing Double ball bearing is the most durable fan construction with a durability of over 50,000 hours. Double ball bearing has at least twice life as sleeve bearing. Extreme durability and overclocking The graphics card uses the 8 + 2 power phase design to allow the MOSFET to operate at lower temperature, and over-temperature protection design and load balancing for each MOSFET, plus the Ultra Durable certified chokes and capacitors, to provide excellent performance and longer system life. NVIDIA NVLinkTM Support Support for NVIDIA NVLinkTM (NVIDIA SLI) technology, which combines 2 identical GPUs with an GeForce RTX NVLink Bridge to deliver the ultimate experience in 4K gaming or VR gaming. You can also adjust the light effect on the bridge with the AORUS Engine. POWER INDICATORS The smart power LED indicator alerts the player when any PCI-E power supply is abnormal.
