Gigabyte has added a new Nvidia GeForce GTX 1080 based graphics card to its roster. The Gigabyte GeForce GTX 1080 Turbo OC 8G (GV-N1080TTOC-8GD) is notable for its new WindForce 'Turbo Fan Cooling System' which is a lateral blower style cooler with a trio of integrated copper composite direct touch heat pipes.

Before having a closer look at the new cooler, please take some time to digest the official key features and specs provided by Gigabyte:

Features

  • Powered by GeForce GTX 1080
  • Integrated with 8GB GDDR5X 256-bit memory
  • Turbo Fan Cooling System
  • Support up to 8K display @60Hz
  • One-click overclocking
  • Intuitive Xtreme Engine

Core Clock

  • Boost: 1797MHz / Base: 1657MHz in OC mode
  • Boost: 1771MHz / Base: 1632MHz in Gaming mode

Gigabyte's new WindForce 'Turbo Fan Cooling System' propels warm/hot air from the back of your PC chassis much like the Nvidia Founders Edition card. Furthermore, this two PCI slot wide card includes a trio of composite material heat pipes which combine thermal conductivity and phase transition cooling effects for a claimed 19 per cent increase in cooling capacity. The three 6mm heat pipes make use of Gigabyte's usual 'direct touch' construction to take heat directly from the GPU die. An aluminium plate helps draw heat from the memory and VRM.

The GeForce GTX 1080 Turbo OC 8G features 8+2 power phases for easy overclocking and, as usual, Gigabyte has constructed this graphics card using ultra durable components. The card is compatible with Gigabytes Xtreme Engine OC and monitoring tool.

Gigabyte has yet to provide pricing and availability information.

Am i missing what part of the heat-pipes are composite, they look like your bog standard heat-pipes.

Yeah, you are missing it. Composite means made up of various parts or elements as that is. A bog standard heat pipe would just be a copper tube.

Not quite true. A conventional heatpipe contains a phase change coolant, and the inside is coated with a wicking structure that returns the coolant to the heat source once the vapour has condensed. The gigabyte “composite” pipe has an additional inner tube which I assume increases its thermal capacity (although quite how that would interact with the phase change aspect is another question).

But basically, a conventional heatpipe has the coolant in a single tube, this one has it sandwiched between two tubes.

My understanding of composite is a little different, i thought it meant something made up from two distinctly different materials, something that, despite combining two types of heat-pipes wick structures (sintered & grooved), this isn't, it's still a copper pipe with grooved wicks containing another copper pipe with sintering.

AKA distilled water. :)

The word simply means composed of more than one element. It's probably most often used when referring to materials, but that's by no means its only usage. In this case it's referring to the use of both grooved channels and sintering; conventional heatpipes would normally have one or the other.

Commonly, but not exclusively. Both Methanol and Ethanol are also used in room temperature heatpipe systems, and I suspect that in industrial systems there are more esoteric liquids employed. For a GPU cooler, though, it's certainly likely to be water-based.
