Thermalright introduced the Royal Knight 120SE, a dual fin-stack CPU cooler with a design focus on clearance with the memory area of your motherboard. It does this by offsetting its two fin-stacks away from the memory area, with one of them being almost directly above the CPU base, and by using a slim 15 mm-thick intake fan. The heatsink measures 122 mm × 114 mm × 155 mm (DxWxH), with the intake fan adding another 15 mm depth. The cooler features a nickel-plated copper base, from which six 6 mm-thick copper heatpipes pass through, skewering the two aluminium fin-stacks on both ends.

The intake fan is a Thermalright TL-C12015B. This 15 mm-thick 120 mm spinner features a 2nd generation fluid dynamic bearing, turns at up to 1,800 RPM, pushing up to 59 CFM of airflow at 1.24 mm H₂O static pressure, and 26.1 dBA maximum noise. The second fan is meant to be installed between the two fin-stacks. It is a TL-C12B V2, a 120 mm fan of conventional 25 mm thickness, and featuring a fluid dynamic bearing. It turns at speeds of up to 1,500 RPM, pushing up to 66.17 CFM of airflow, at 1.53 mm H₂O static pressure, and 25.6 dBA maximum noise. Both fans lack any kind of lighting, and use a standard 4-pin PWM power input. Among the CPU socket types supported are LGA1851, LGA1700, AM5, and AM4. The company didn't reveal pricing.
