TechPowerUp posted pictures of Gigabyte's new Radeon HD 7870 and Radeon HD 7850 graphics cards with the company's WindForce 3X cooler. The 7870 model is said to feature a 5-10 percent factory OC, while the 7850 features a 5 percent OC.
The HD 7870 card, the GV-R787OC-2GD, makes use of a long Ultra Durable VGA+ PCB by GIGABYTE, outfitted with the company’s best air-cooling solution, the WindForce 3X, which has been used on a variety of high-end graphics cards by GIGABYTE. The card is also said to feature a 5-10% factory OC.
The HD 7850 card, the GV-R785OC-2GD, features a shorter PCB, and features a more compact twin-fan WindForce Anti-Turbulence cooler. This model features a 5% OC, too. The WindForce 3X uses a combination of monolithic heatsinks and aluminum fin stacks suspended over copper heat pipes, ventilated by three fans that are slightly inclined, to reduce turbulence, and push hot air towards the vent on the rear panel.
