True to the spirit of Noctua’s redux line, the NH-U12S redux is a streamlined, accessibly priced version of the iconic NH-U12S that has established itself as a benchmark for slim, highly compatible 120mm CPU coolers. The redux version uses the same proven heatsink layout that guarantees 100% compatibility with tall RAM modules as well as excellent case and PCIe compatibility. Thanks to the popular NF-P12 redux-1700 PWM fan with automatic speed control, it provides high performance under load and runs whisper-quiet at idle. At the same time, Noctua’s renowned, professional SecuFirm2™ mounting system and the pre-applied NT-H1 thermal compound make installation child’s play.the NH-U12S redux is a smart, affordable choice for a quiet, high-quality 120mm cooler.
