The NH-U12A chromax.black is an all-black version of Noctua’s award-winning NH-U12A premium-quality quiet CPU cooler. Thanks to the same proven asymmetrical single-tower heatsink design and state-of-the-art NF-A12x25 PWM fans, it stays true to the NH-U12A’s successful formula of fusing best-in-class cooling performance with superb quietness of operation and outstanding RAM, case and PCIe compatibility. At the same time, the chromax.black version with its black fans and black coated heatsink combines these assets with a sleek stealth look. Topped off with the renowned SecuFirm2™ multi-socket mounting system, Noctua’s enthusiast-grade NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-U12A chromax.black is a deluxe choice for customers who seek a highly compatible 120mm heatsink that can rival the performance of 140mm units and looks just as great as it cools.
• Key Features
140mm Performance in a 120mm Size: Thanks to a deeply optimized layout featuring 37% more fin surface area than its predecessor and a massive 7 heatpipes, it easily matches the thermal dissipation of much larger, bulkier coolers.
Dual NF-A12x25 PWM Fans: The gold standard of PC fans. The push/pull dual-fan setup utilizes Noctua's flagship NF-A12x25 fans, made from Sterrox® liquid-crystal polymer, delivering unprecedented static pressure and near-silent operation (max 22.6 dB(A)).
100% RAM Compatibility: Due to its brilliant asymmetrical design, the cooler does not overhang the RAM slots on Intel LGA1700/1200 or AMD AM4/AM5 motherboards, ensuring you can use memory modules with tall RGB heat-spreaders without issue.
100% PCIe Compatibility: Measuring 125mm wide with the fans installed, the NH-U12A stays completely clear of the top PCIe x16 slot on standard ATX and Micro-ATX boards, ensuring thick RTX 40-series and 50-series GPUs fit perfectly.
SecuFirm2™ Multi-Socket Mounting: Noctua’s legendary mounting system provides perfect contact pressure and frustration-free installation for all modern Intel and AMD sockets, including an offset mounting option for AM5 to maximize die-cooling efficiency.
Pro-Grade NT-H1 Thermal Paste Included: Everything you need is in the box, including a tube of Noctua’s award-winning NT-H1 thermal compound for minimum thermal resistance.
• Performance / Technology
Running at a maximum speed of 2000 RPM (pushing 102.1 m³/h of airflow), the fans can be dialed down using the included Low-Noise Adaptors (L.N.A.) to cap the speed at 1700 RPM for virtually silent operation. The entire heatsink is constructed from copper (base and heatpipes) and aluminum (cooling fins), fully soldered and nickel-plated before receiving the black coating to ensure zero thermal degradation.
• Design & Ergonomics
Standing at a highly accommodating 158mm tall, the NH-U12A fits comfortably inside almost all modern mid-tower cases. The chromax.black aesthetic is perfectly uniform; even the anti-vibration pads and mounting brackets are black. It can also be color-customized using optional Noctua NA-HC7 or NA-HC8 heatsink covers.
• Compatibility / Use Cases
Fully compatible out of the box with Intel (LGA1851, LGA1700, LGA1200, LGA115x) and AMD (AM5, AM4). It is the definitive air-cooling solution for hardcore gamers, overclockers, and silent PC enthusiasts who refuse to risk the potential leaks or pump failures associated with liquid AIO coolers.
• Why This Product Stands Out
Most air coolers force you to choose: compact size or extreme cooling power. The Noctua NH-U12A chromax.black stands out by offering both. It fits perfectly in mid-tower cases without blocking expensive RGB memory, yet cools 200W+ flagship processors efficiently and silently, all backed by an industry-leading 1-year manufacturer's warranty.
