Installation of the Phanteks PH-TC14CS is not that complicated, but if it is your first time installing a CPU cooler you may have some issues. We have made an installation video to make things easier for you.
Our installation took a little longer than expected. The most difficult thing was locking the heatsink onto the CPU socket. While you can get it on there very easily using the little wrench that is included to actually tighten the screws takes some time. I would have liked to see Phanteks use something like we saw on the Noctua NH-L12, where you were able to put the wrench through the top of the heatsink.
Everything else as far as installation goes went pretty good. You will need to make sure the memory you are using will fit with the PH-TC14CS as the bottom fan can get in the way, especially on socket 2011 motherboards. Also you are probably going to want to install the memory right after you put the headsink on, before you install the fans.
