Very effective 179

1) King, you have verified at least 33 cm long in place in your case.
2) If you have a card with the cooler ref, everything is explained. However if you have a custom cooler, it can be more complicated. I had a gainward Phamtom gtx770, and there was a plate cooled RAM and VRM, I wanted to leave. I had to be inventive to be able to adapt the system.
3) Beware of screws that can be fragile, I farted a screwing a bit too, so tighten too hard, it is useless.
4) There is a system just get over to reattach the card I was not able to but it did not really annoying if you tighten the clamp PCIe well.

Side performance, you do not tighten disappointed: this system can cool 300W.
The card I have a 2.0 boost to 1241 MHz she could not hold as it rose rapidly to 85 ° and thus came down to 1150 MHz while making a lot of noise.
With this new cooler, I could overclocked to 1306 MHz the @ 1.21V (max limited by NV), with equal or lower temperatures depending on the game. (83 ° on Tomb Raider in 1440p, FXAA, TressFX, Ultra). All in was very little noise.
The backplate does wonders to properly cool the PCB.
To further maximize performance, I recommend an extraction fan on the side (in addition to regular on the front to blow fresh air)

Conclusion: For DIYers who are not afraid, but otherwise I really recommend.
