The NH-U12A is the latest, 5th generation of Noctua’s NH-U12 series of 120mm size premium-quality quiet CPU coolers. Conceived to push the envelope of the 120mm form factor, it combines two of Noctua’s flagship model NF-A12x25 PWM 120mm fans with a completely redesigned heatsink featuring 7 heatpipes and an increased fin surface area for superior heat dissipation. This way, the NH-U12A can rival the performance of many 140mm size coolers while offering 120mm class case and PCIe compatibility. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system and Noctua’s proven NT-H1 thermal compound, the NH-U12A is a deluxe choice that combines top-tier performance with excellent compatibility and outstanding quietness of operation.
