I haven't done any overclocking but I've been happy with the 2700x with the stock Wraith Prism. The only issue I had was that I could not get it to remain stable when gaming using a GTX970. It would run fine for a couple of minutes then video would drop. Game would continue with no problems...
Keep in mind this is only good for a couple of metro areas so far. San Francisco Bay Area, Fresno CA and Greater Boston MA.
Using google maps found an address that worked. Looks interesting for those that it works for.
