Product review (5 stars): Look great and slight temperature reduction on GPUs.
I bought two of these, one for each of my GTX 970's. They were very easy to install, you just need to remove 7 screws and they give you 7 screws which are longer in replacement of those screws. Screw in the back plate and bam you're done. They look great and have reduced my GPU temps by 2-3C at idle.
