Hmm, the same question was asked above for an older generation CPU. The answer back then was that it is enough for this CPU if no overclocking is done. At that time it was a 1700x now 2 generations later I would tend to think that this one could be quite scarce. I assume you chose this cooler because it is quite low and you might not have much room in the case for a bigger one.
You might even be better off with the boxed one. The boxed should be enough, but it is not the quietest and it only does what is necessary. I think there are better alternatives. If you have enough space, I would suggest a be quiet one:
be quiet! cooler Shadow Rock TF 2 (11.20cm)
but this one doesn't come with thermal paste, so you'll have to get that separately.
