Got a noisy 5th Gen NUC from 2015 or a 7th Gen unit from 2017? It's not too late to make it silent using Akasa's Plato, available at half price on Amazon. Ditch the fan and enjoy a brand new computer with the Plato X, compatible with the Broadwell NUC (NUC5i7 / NUC5i5 / NUC5i3) or the Plato X7 compatible with the Kaby Lake NUC (NUC7i5 / NUC7i3).
