As speculated by the PCB of GeForce GTX 1080, the same pattern of holes found in the GeForce GTX 900 series. Means the new card can take advantage of already available 3rd party GPU coolers in the market. Building on that, the German portal PCGameshardware mounted Arctic Accelero Xtreme IV cooling system and Overclocked GeForce GTX 1080 at about the same frequencies displayed during the official presentation,  2126 MHz  (vs 1780 MHz reference GPU Turbo frequency).

Unfortunately, the limitations of using a reference model are at first glance, the GPU have single PCI-Express 8 – pin connector, so the Overclocking is limited to 120% of TDP and the GPU cannot consume more than 215W (8-pin connector + PCI-Express slot can deliver up to 225W), so we can assume that with the arrival of custom models we will see a really powerful graphics card. It’s best to avoid the reference version of GeForce GTX 1080, if you want to have a powerful graphics card.
By using this advanced cooling system (another point for custom models), the temperatures were under 50c running DOOM. We can summarize all by saying that, it is not the temperature that is keeping Pascal GP104 from achieving higher clocks, but board power limit.
