Gigabyte GeForce GTX 1070 Ti Gaming 8G - graphics card - GF GTX 1070 Ti - 8 GB

The WindForce 3x cooling system features 3 unique blade fans, 2 composite copper heat pipes, heat-pipe direct touch and 3D active fan functionality, together delivering an effective heat dissipation capacity for higher performance at lower temperatures. The airflow is spilt by the triangle fan edge, and guided smoothly through the 3D stripe curve on the fan surface, effectively enhancing the air flow over traditional fan. The 3D Active Fan provides semi-passive cooling, the fans will remain off when the GPU is under a set loading or temperature for low power gaming. It allows gamers to enjoy gameplay in complete silence when the system is running light or idle. The LED fan indicator on the top of the graphics card provides an instant display of the fan status. The composite heat-pipes combine both thermal conductivity and phase transition for efficiently managing the transfer of heat between two solid interfaces which increases cooling capacity.

The pure copper heat pipes are shaped to maximize the direct contact area to the GPU for enhanced thermal transfer. The heat pipes also touch a large metal base plate covering the VRAM module via thermal pads to ensure the critical cores are properly cooled. Compared to the reference design, the 6+2 power phases on the card make the MOSFET working at a lower temperature and provide more stable voltage output. Over temperature protection and load balance to each MOSFET can effectively extend the card life.
