Know before you buy
The cooler stands 158mm tall, so it fits in the vast majority of mid-tower and full-tower cases. We recommend checking your case's maximum CPU cooler height clearance in its specifications to be certain.
No, the NH-U12A is specifically designed to be slim. It provides 100% RAM compatibility on most motherboards, meaning you won't have to worry about clearance issues with taller memory sticks.
Yes, the dual NF-A12x25 fans are engineered for extremely quiet operation. With PWM control, the fans will only ramp up speed when your CPU is under heavy load, keeping noise levels minimal during everyday tasks.
Yes, the box includes the SecuFirm2 mounting kit, which supports a wide range of Intel and AMD sockets, along with a tube of premium NT-H1 thermal paste. You will only need a standard Phillips screwdriver to complete the installation.
The NH-U12A delivers 140mm-class cooling performance, making it capable of handling many high-TDP processors. While it is excellent for most builds, those running extreme overclocking setups may still prefer a larger liquid cooling solution.
No, the NH-U12A is a performance-focused air cooler and does not include any RGB lighting. It features a classic, industrial aesthetic suited for builds where clean, functional design is the priority.
