Not bad for a single heatsink cooler, the price is to close to the NH-D14 in my opinion though.
If it's a smaller cooler you need because of space, or if you are not OCing much then this one will do the job good enough. Otherwise for £10 more, which is less than the price of an extra Noctua fan for the NH-U12S, the D14 is the better option.
