Thermalright today released the Ultra 120EX Rev. 4, a classic tower-type CPU cooler. The cooler is the fourth revision of the Ultra line of coolers by the company, and offers an updated fin design, as well as a high static-pressure fan. Six 6 mm-thick nickel-plated copper heat-pipes draw heat indirectly through a copper base with the same electroplating (you can pair it with liquid-metal TIM without worrying about corrosion). These heat pipes pass though an aluminium fin-stack with 52 S-shaped fins that are 0.4 mm-thick and spaced 1.6 mm apart. The fin-shape increases turbulence for improved heat-dissipation to the airflow.

The included TL-B12G 120 mm fan turns at speeds of up to 2,150 RPM, pushing up to 69 CFM of airflow, at 2.87 mm H₂O static pressure. The fan features a long-life fluid-dynamic bearing. With its fan in place, the Thermalright Ultra 120EX Rev. 4 measures 132 mm x 89.6 mm x 157 mm (WxDxH), weighing 865 g. Among the CPU socket types supported are AMD Socket AM5, AM4; and Intel LGA1700, and LGA1200. The company didn't reveal pricing.
