I'd go with the Cryorig H5, but the stock cooler on the 2700x should be able to get you 4ghz. It is a really good stock cooler. I would try it out first and see how it performs and make a decision then.
For some reason stock cooler gives me min. 50C on idle (@4GHz) and yes I did check that cooler was properly mounted, applied new paste a.k.a the premium type, changed settings in BIOS, but nothing so idk.
