We review three Noctua CPU coolers designed for Ryzen Threadripper / X399 motherboards with Socket TR4/SP3. All three coolers tested have recently been introduced into the channel with kicks performance and versus some really nice airflow, PWM controlled fan. Noctua is re-using their older model NH-U9 - NH-U12S NH-U14S, however, revamped base cooling base plate and the mounting mechanism to fully cover the Threadripper heat spreader.
