The PHANTEKS C399a CPU watercooler from the Dutch case manufacturer is compatible with AMD’s Socket TR4 and thus compatible with the Threadripper range of CPUs. The HEDT CPUs (High End Desktop) from the Texan chip manufacturer require a CPU cooler with a particularly large surface area to effectively transfer heat. The premium design of this CPU cooler, which also comes with RGB-LED lighting, combines extremely high-end materials and leaves no room for misunderstanding – this is Phanteks quality design at its finest!
Cooling fins with a height of 5 mm are located on the nickel-plated copper baseplate to enable optimal heat transfer and the transparent and polished acrylic glass cover is attached with the help of a Viton O-ring. The top of the acrylic cover comes with the 1/4″ threaded ports as well as embedded RGB-LEDs.
