Product Showcase
The GeForce GTX 1070 founders edition is 10.5 inches in length which is roughly 27 cm so it should fit comfortably in pretty much any decent chassis. The cooler that GTX 1070 uses is vapor chamber cooling, for a < 250W design graphics card, similar to its bigger brother the 1080.
When we open it up, on the inside we spot a copper vapor chamber, which is able to draw more heat off the GPU and components on the PCB including memory and VRM, ultimately allowing the GPU to run cooler and thus boost to higher clock speeds.
This vapor chamber is combined with a large, dual-slot aluminum heatsink to dissipate heat off the chip. A blower style fan then exhausts this hot air through the back of the graphics card and is exhausted at the exit to the left.

A four phase power supply is responsible for supplying the GP104-200 GPU with power. An additional power phase is dedicated to the board’s GDDR5 memory. As you can see, the bottom of the cooler functions as a front-side plate drawing heat from essential components.
You will have some extra power allowance, the reference/Founders board design supplies the GPU with 225 Watts of power at the maximum power target setting of 120%. The board uses polarized capacitors (POSCAPS) to minimize unwanted board noise, as well as molded inductors.
