Noctua considers the U12S redux as acceptable:

But, being a single tower cooler, the effectiveness depends some on what your processing load is.
If you are fully loading all 24 processing threads, you will generate much more heat than when gaming and stressing only a handful of cores.

As a note, the U12s redux is a budget version of the NH-U12s.
It comes with only pre-applied paste and a budget fan.
