A notable feature of the CNPS14X Duo Black is its unique reverse direct-touch heatpipe base, a patented ZALMAN technology. This design diverges from the conventional direct or indirect contact methods by fully enclosing the heatpipes within the base-plate, allowing for comprehensive contact with the CPU across the entire surface area of the heatpipes. The heatsink incorporates six copper heatpipes, each 6 mm thick, extending through two aluminum fin-stacks, which are finished with ABS top-plates.

The cooling system includes two ZALMAN AF120 fans. Users can opt for a push-pull configuration utilizing both fans, providing 44 mm of memory clearance, or a single fan setup for 52 mm of memory clearance. The fans operate at speeds ranging from 600 to 2,000 RPM, delivering a maximum airflow of 69.12 CFM, with a peak static pressure of 2.01 mm H₂O and a noise level up to 29.7 dBA. The fans' hydro dynamic bearings have a lifespan of 40,000 hours.

The CNPS14X Duo Black supports various CPU socket types, including Intel LGA1700, LGA1200, AMD AM5, and AM4. Additionally, it comes with a sachet of ZALMAN ZM-STC8 thermal compound, which has a thermal conductivity rating of 8.3 W/mK. ZALMAN has not disclosed the pricing for this cooler.
