Phantom cooler design

Gainward GTX 770 Phantom, continue the elegant design of the Phantom cooler. The Phantom comes with brand new fans design (patent pending) that includes
1)Removable fan design – each fan body can be removed to clean if necessary
2)5 pieces of 8mm copper heat-pipe and copper base - better thermal performance
3)solid structure
With this new outstanding innovated thermal design and optimized product design Gainward GTX 770 Phantom delivers an extreme gaming performance for enthusiast gamers.

  With the Phantom cooler, Gainward GTX 770 Phantom with factory over-clocked speed gets 7.8dB quieter or 60% lower than reference board under full load operation.
  Thanks to the Phantom cooler, Gainward GTX 770 Phantom with factory over-clocked speed performs 15℃ lower GPU temperature than reference board with reference clock.


/ Features /
8-phase PWM
Gainward adds three extra phases for power supply of GPU core that helps to supply more fuel to the 3D graphics engine and share the current load with other 5 phases to reduce the max operating current. With those 8 phases work together, Gainward GTX 770 Phantom can be over-clocked easily and safely , the overall efficiency can be improved, the choke noise and EMI noise also be reduced.

Gainward continues using DrMOS in those 8 phases PWM for core power circuit. DrMOS is designed to handle high current with low noise operation and less heat generating.
Gainward Great 8 cm silent PWM fans
Great 8 cm silent PWM Fan (GR8) achieves highest cooling performance at much lower temperatures under power saving mode.
Gainward Grand-Prix Heat-Pipes
Hybrid Cooler
Gainward Grand-Prix Heat-Pipes Hybrid Cooler, was designed in 8 mm copper heat-pipes on a copper base conducting heat away from GPU at highest efficiency, then dissipating onto aluminum heatsinks, which are forced ventilated with Great 8 cm silent PWM fans (GR8).
QuattroPorts, 4-ports-in-1 Universal HD connectivity
Gainward provides 4 ports in one, fulfills universal connectivity to diverse displays in extreme high-definition resolution. Dual View is supported with ease without bothering connector conversion.

*Gainward GeForce® GTX 770 Phantom integrated “QuattroPorts -Display Port, Dual Dual-Link DVI, HDMI”.
